Re: Time off running z/VM 5.4 1101 on z196 for first time
Is the SE clock update you describe performed on z9's? We did a POR a couple weeks ago and the clock was off by about 27 minutes afterwards. I t didn't get caught for a while. The z/OS images now have their TOD prompt re-enabled and the POR instructions now include a step to check the SE clock for accuracy. I assumed it was off due to the drift in the SE clocks since the last POR several years ago.

At that time the LPAR epoch [delta from CEC TOD] will be reset to zero, assuming it hasn't been set to a non-zero value in the LP AR image profile. The System z TOD clock is the best clock in the CEC; a precision timepie ce that even detects and adjusts for its own drift (up to a point). If you have STP or ETR, then the TOD clock is also accurate. In that respect, Sir Rob's point about using your wristwatch as a time reference is on point. The SE historically syncs its standard PC battery operated clock (BOC) t o the CEC TOD every 24 hours. The BOC instantly moves forward or backward . Why bother? Because at POR, the only time reference is the SE BOC -- th e CEC TOD will be set to that value. Once accurately set, the time on the CEC is better since it has comparatively little drift. Starting the z196 GA2 upgrade and the z114: o The SE BOC will sync to the CEC TOD once an hour instead of once a day , improving CEC TOD accuracy after POR. o The SE BOC will be steered the match the CEC TOD instead of making lar ge jumps, avoiding a Paradox that could destroy the universe. o OK, so there's no Paradox, but there are NTP-using firmware components in a zBX environment that benefit from the steering You still need STP to have *accurate* time.

Re: Anyone use The Hessling Editor (THE), an Xedit/Kedit look-alike, for off-line VM code development or personal use?
I've used KEDIT KEX extensively on the PC for decades because its similarity to XEDIT REXX made working in both environments easier. I have never used THE. I would be interested in your, or anyone else's, views comparing contrasting THE Regina with KEDIT KEX. Are there any benefits/features that could entice me to switching to THE/Regina?

Re: PIPEDDR and attached DASD
I have solved this problem and present the resolution for the benefit of others: it was an MTU mismatch between the VM TCPIP stacks (set at 8992) and what the network between would support (1500). Further testing I did had showed that ATTACH vs. MDISK and the versions o f PIPELINES and PIPEDDR were not the cause. Instead, sucess or failure was dependent on the data being transferred and whether it traversed the external network or not. After ripping apart PIPEDDR to understand it so that I could add debugging code and options I found that the transfer for a particular disk always failed at a unique track within that disk. Manually added pacing (via DELAY stages) would work (although *tediously* more slowly than expected based on the delay value used), but not if the delay was too small. Eventually, while looking for pacing information in the TCPIP stack I read the reference that Selecting an MTU size that is too large may cause a client application to hang. The light bulb went o n and after adjusting the MTU size used in the VM TCPIP stack everything works fine now.

A had it as its 191 R/W disk, B had it as its 191 R/O disk.The the manual link command used was LINK * 191 191 RR. If that got a different disk, then there was an error in the processing of the LINK command - the directory entry is LINK A 191 191 RR. When the profile was updated, both A and B were logged off and the update was done from another id, mine. We still do not have an answer. It has all of the appearances of being a cache problem of some kind. MDC should have kept things straight since these were two guests of the same CP. DASD cache should also have given both users the same answer. It appears as though A was being given data from a cache, and the cache was being bypassed by B. That would be understandable if the guests were in different LPARS or on different CECs and MDC were in use; however, they were in the same LPAR, hosted by the same CP, using the same I/O hardware and program interfaces. If not a cache problem, then the ACCESS command could have been giving 9ncorrect results, i.e. using the active ADT for A and the inactive for B.

I then logged A on and checked its configuration. It reflected the changes from the PROFILE. It AUTOLOGGed B. B came up using the old profile. I stopped the server code on B and checked the configuration. It was indeed the old profile that was used. A q links 191 showed that A had it as its 191 in R/W mode, while B had it as 191 R/O. A list profile exec * found only one such file, on the A disk, , and on B it was the old configuration. I then logged both off and xautologged A. Again, B came up with the old configuration. I tried the logoff/ logon sequence several times, all with the same result. I finally detached the 191 disk from B and relinked it. This time, the new profile exec was there, like it should have been all along. How is this even possible? Are we going to be plagued by this every time we xautolog A?

We will have to resync the dasd after the test has been completed. The main system will stay up and running so that those who are not part of the test can continue working. If you'll indulge me, I have a side question: When you break the replication in order to perform a DR test this puts updates to your production site at risk of loss should a real disaster occur during your DR test. Is there something else in your setup that elimtates this risk or has management signed off on the risk? To eliminate the risk I would expect a setup whereby the mirrored copy gets flashed to a tertiary copy and the DR test conducted from the tertiary copy and replication is never broken. If you have an alternate setup that eliminates the risk I would be interested in what it is. Brian Nielsen
Re: High Level Assembler

Re: Cannot TELNET to Level 2
I think the you are probably issuing the COUPLE command from the wrong place. You need to issue it from your 2nd level guest userid as a comman d to your 1st level system to COUPLE to an OSA2LAN defined in your 1st leve l system. The best time to do this is after you logon to your 2nd level guest userid before you IPL it. Keep in mind that COUPLE is a class G command, so your couple 9012 commands failed because the userid you are doing it from does not have a virtual 9012 device. It's also hard to tell from your narrative whether OSA2LAN was defined on your 1st level system (where it should be) or in your 2nd level system. You might benefit from drawing yourself a picture of your 1st 2nd l evel systems showing what structures addresses exist where in the hierar chy. This will help you correlate what commands need to be issued with where hey need to be issued.

Re: Testing TCPIP and VSWITCH at Level 2
As an alternative to attaching OSA triplets to your 2nd level system, use NICDEFs in your 2nd level system and couple them to your normal vswitch. In either case, you still need to make sure you don't create duplicate IP addresses. That's where a coupling to a new disconnected vswitch will guarantee isolation -- a good feature when you are learning, playing, and testing.

Re: Applying Maintenance - Best Practice
tyvm, really sweet. So we can have our cake and eat it too. If I understand what you are saying. The real volser is on cylinder 0. But since we define minidisks from cylinder 1 to whatever, the minidisk, virtual disk, volser is defined on cylinder 1. Since DDR never really cares about or writes the last cylinder, though i t complains, we can DDR to the minidisk, virtual disk, just as we would a to real disk and all is copacetic, at least as long as IBM does not mess with this. (Hope Alan is not listening). DDR does care and will try to copy the last cylinder, hence the error message it will produce. It's that *we* don't care because we leave empt y the cylinder that won't be copied. Which brings up the previously unmentioned point that for your PAGE and SPOOL packs you should *not* allocate that last cylinder as PAGE or SPOL. In practice it will rarely make a difference unless your 2nd level system runs short on PAGE or SPOO L space - at which point it will abend when it tries to write to the cylinder it thinks is available but is beyond the end of the minidisk.

Re: Applying Maintenance - Best Practice
You can see your current allocations with the Q ALLOC PAGE and Q ALLOC SPOOL commands. You can change the allocations with CPFMTXA by using the ALLOCATE option. It's all documented in the CP Commands and Utilities manual. Each volume has it's own allocation map, so you'd have to change it on each one. Doing so on your running 1st level system would be considered a dangerous procedure, so don't do it without a full understanding of how to do it safely. In general, this involves bringing all your guests down, backing up SPOOL space with SPXTAPE, making the changes with CPFMTXA, shutdown re-ipl, and reloading SPOOL space from your SPXTA PE backup. The best time to set the allocations properly is when you are initially installing VM, but the book doesn't tell you that it even needs to be considered. At this point, the simpliest course of action would be to do either of 2 things: 1) Don't worry about it at all since it only effects the 2nd leve l system and only if comes close to filling PAGE or SPOOL space, or 2) whil e the 2nd level system is down, link to the 2nd level PAGE minidisks and us e CPFMTXA to change their allocation maps, and don't worry about the SPOOL minidisks since you'll periodically be refreshing them via DDR anyway. I would recommend option 1, not worrying about it since this is just a test 2nd level system for you. If your 2nd level system fills up PAGE or SPOOL you've probably got other issues that would have ended badly sooner or later anyway. If you eventually want to fix your 1st level system, your 2nd level test system is the perfect place to test your procedures before you do it 1st level!

After updating the VOLSERs, I am just trying to clone the 1st Level Directory to the 2nd Level without destroying the 1st Level system. And then IPLing. If you've DDR'd your 1st level packs into minidisks defined for your 2nd level guest you shouldn't have to do anything at all to your 2nd level directory. Just logon to your 2nd level guest and IPL it. If for any reason you *need* to update your 2nd level directory, it's safer to do it from your running 2nd level guest than from your 1st level system. Pretty easy to do and no chance of messing up your 1st level system. In extreme situations there is the NODIRECT option available in the IPL prompts that you could use in your 2nd level guest. See chapter 3 in the Systems Operation manual. Another thing that will help you work with your 2nd level system is to give it a small 191 minidisk. This gives you an easy way to make files available to you in any of the userids in your 2nd level guest. Once you r 2nd level system is running, just ATTACH 191 to whatever userid in your 2nd level system needs the files. In this case, you might have a source directory on it, and once you've done an IPL 190 in 2nd level's OPERATOR just ATTACH 191 to OPERATOR at an available address and ACCESS it. Brian Nielsen

Re: Applying Maintenance - Best Practice
Having 2 Page and 2 Spool is small enough that it's extremely reasonable to make that much available to your 2nd level test system. SPOOL is all or nothing when DDRing them. Copy them both whenever you want to be sure your 2nd level test system has current versions of what i s in 1st level Spool space. Mostly you probably only care about the SDF spool files, and they generally only get updated when you apply maintenance. And you are correct - you'll need to do a FORCE start. PAGE can be just some, as long as you have enough for the paging load in your 2nd level system. You don't need to copy the Page volumes each time. One time is good forever. Again, with only 2, copy them both and be done with it.

This past Saturday, we performed our first DR test with our current setup (1 z/OS system and 1 z/VM with multiple-z/VSE). Since we have not been able to get the backup performance from either z/VM or z/VSE that z/OS provides, we backup both systems (2 z9s) from z/OS. During recovery, the z/OS system DSF's all devices to LABEL them and then restores them from the library. Well, the setup is a z/VM floor system with z/OS and our z/VM under it. All of the DASD is MDISK DEVNO'ed in 1st level VM. After a DASD label has changed it's not reflected on the 1st level VM until a VARY OFF/ON is performed. Since z/OS is performing the labeling, it would be best for it to do the VARY OFF/ON. Other thoughts? Since your DASD is given to your 2nd level DR guests via DEVNO your 1st level system doesn't care what the label is. I submit that varying them OFF/ON is not needed at all.

Re: what is a 'full pack' minidisk?
I second what Jim Hughes said - essentially that if it doesn't include cylinder 0 it's just a minidisk, no matter what the size. Personally, and as discussed here by others in the distant past, I prefer to not give out the last cylinder of a real volume in order to make it much easier to copy a 1st level volume for 2nd level testing. Doing this is just an extention of the same logic that leaves the last cylinder of the system volumes empty by design (as requested of IBM by user groups). So now you need a term for a 1 to (END-1) minidisk :) On a related note, I don't like using END in the first place because it's not obvious how big it is unless you know the size of the volume.

Now since I had to destroy the VSWITCH and re-define with the new real OSA UCB do I need to recycle the Linux guests that are using that VSWITCH or is there another way without bringing the Linux guest down? First check that the linux guest is in the access list for the new vswitc h (see Q VSWITCH ACCESSLIST) and add it if not (see SET VSWITCH GRANT). Then use the CP COUPLE command for the linux guest to connect it to the vswitch. FWIW, it's too late now, but you could have just added the new address to the vswitch instead of destroying and recreating the vswitch. I've done that when migrating from one OSA port to another.

DDR control cards from IPL device??
Has anyone else ever used the process for supplying DDRXA control
statements from the IPL device? The doumentation in the System Operation
manual is pretty straightforward, but it doesn't seem to work (z/VM 5.4,
SLU 0802).
I have written a tape with 2 files. The first file is a copy of IPL DDRX
A
that has had some DDR control statements appended to the end (as per the
doc):
SYSPRINT CONS
INPUT 181 TAPE (LEAVE
OUTPUT 2000 DASD
RESTORE ALL
The second file is a standard DDR DUMP.
DDR starts fine when I IPL the tape, and at the initial DDR prompt I give
it a blank ENTER. The DDR RESTORE then recognizes the volume label that
was dumped (as is indicated in the first record in the DDR DUMP in file
2), but then the DDR RESTORE appears to be trying to interpret the
remaining records in file 2 as DDR control statements. Here is a console
log:
begin console snippet
IPL 181 CLEAR LOADPARM 9
z/VM DASD DUMP/RESTORE PROGRAM
ENTER CARD READER ADDRESS OR CONTROL STATEMENTS
ENTER:
HCPDDR717D DATA DUMPED FROM VMM191 TO BE RESTORED
DO YOU WISH TO CONTINUE? RESPOND YES, NO OR REREAD:
yes
THR {-
HCPDDR702E CONTROL STATEMENT SEQUENCE ERROR
THR {-
HCPDDR701E INVALID OPERAND - THR
end console snippet
Lots of additional the HCSDDR702E messages have been omitted for brevity.
Adding a PROMPTS OFF DDR control statement gets the same result, but
without the DO YOU WISH TO CONTINUE? prompt response.
Using MOVEFILE to copy the 2 tape files back to disk for inspection shows
that they have exactly what I'm expecting them to have.
The THR lines are records 2+ of the second file (which DDR DUMP wrote).
As one of numerous tests, I replaced the RESTORE ALL with a TYPE 0 0 0
TO 0 0 1 and it performed as expected without errors.
Is there something I'm doing incorrect or should I open a PMR?

Standalone DDR hardware assigns question
My searches haven't found anything that answers this question, and perhap s only Alan will know the answer, so here goes: Does Standalone DDR (directly in an LPAR, not under z/VM) do a hardware assign release for the 3590 tape drive addresses it uses? I'm thinking ahead to an upcoming DR exercise in which while I'm running DDR native in one LPAR some z/OS images are being IPL'd in other LPARs that also have access to the same tape drive ranges. I know z/OS does th e hardware assign when it varies the drive online, and I'm wondering if tha t will negatively impact Standalone DDR's access to the tape drive it is using. Once I'm far enough along that I can run DDR under z/VM I know it won't be an issue because z/VM will do the assign when the drive is attached to a virtual machine. Brian Nielsen

Re: Channel Contention
Being that this is a one-time effort, I wouldn't worry too much about where the bottleneck is because you indicate can't do anything about it anyway. Better is simply to estimate the amount of time it will take to some gross level of precision. If you were going to be doing it regularl y then it becomes a more important question and could drive configuration changes. I know tape drives are not involved in your process, but I do know that DDR is very effective at driving the channel to them. We have a bank of 4 3590's shared between VM and z/OS on 2 ESCON channels. When I had 2 DDR' s writing to 2 of the tapes drives it effectivley saturated the channels from the VM LPAR and the z/OS jobs trying to use the other 2 tape drives suffered horribly. The reports from Velocity's ESAMAP made it easy to diagnose this cross-LPAR interference. (I ended up moving my DDR's to a different time slot.) I mention this to say that it will be good that there will not be other production workload going on to the DASD when you do this. BTW, the 3-4% channel utilization I mentioned in my other post is on 2G FICON channels. Obviously, 4G or 8G channels would make a big difference .

Unfortunately, they are in an earlier time zone, so I cannot get the answer until tomorrow.
Re: Channel Contention
Here are some data points that may help you. When I run standalone DDR to do a DASD-to-DASD copy within a single ESS 800 connected with 4 FICON channels, each channel is about 3-4% busy as reported on the HMC channel activity display, and the CPU is about 1% busy. My quick back of the envelope calculation is that about 25 concurrent DDR's would max out my 4 channels. If your source and targets are on different channels you could estimate getting twice that many before saturating 4 FICON channels. However, my other experiences with mass I/O tells me that the cache in your target DASD controller is also a good candidate to be the bottleneck. Initially the writes will be fast until the controller cache fills up, then it will slow down once it becomes neccessary to wait for tracks to be destaged from cache to disk. Therefore, while the amount of cache in the controller is a critical performance factor in normal workloads, in this situation however much controller cache you have will sooner or later get swamped. At that point you should check your DASD hardware performance guide for it's maximum sustained write throughput rates. Compare that to your channel throughput capacity to decide which one is the bottleneck. Depending on how much data you push, you may even find that the bottleneck starts at the channel and then shifts to the controller after the cache fills up.

Re: Number of MOD-27 Cylinders for a z/Linux guest
To quote the DS8000 Architecture and Implementation Redbook (SG24-6786, p g 101): If the number of cylinders specified is not an integral multiple of 1113 cylinders, then some space in the last allocated extent is wasted. For example, if you define 1114 or 3340 cylinders, 1112 cylinders are wasted. For maximum storage efficiency, you should consider allocating volumes that are exact multiples of 1113 cylinders. In fact, integral multiples o f 3339 cylinders should be consider for future compatibility. That last sentence has always peaked my interest.

The etc makes cheating very hard ;-) The generic solution really is multi-stream pipelines. The idea there is that your pipeline spits the records in two groups based on the first selection, and subsequent stages split the matched records further in two groups, etc. But you need to collect the unmatched records in each phase and pass them all back to the main path (since you did not want to delete them). So you get a network of pipelines that connect at the beginning and end of the process.

OK, got that covered and done. For the latter, let's have at it. :) As I suggested in the requirement: Possible solution would be to provide a SYSTEM CONFIG option (Check_Resource_Alloc_Sanity for discussion purposes) and associated SET command to check LOGIN, DEF STOR, and IPL events to determine whether th e requested resources (default virtual storage size for LOGIN, new value f or virtual storage for DEF STOR, and current virtual storage size at time o f issue for IPL) are greater than the current physical storage and defined paging space. If check is true, then issue a warning message and cancel the action. Option defaults to ON, can be turned off by class A user SET command. Not perfect, but would catch most of the scenarios that have been discussed so far. A scenario that hasn't been mentioned deals with draining a PAGE volume. The calculation of defined paging space might be considered fuzzy if a PAGE volume is being DRAINed. Of course, you could be strict and conside r such a volume as undefined, but there will be cases where storage requirements for a guest are less than the available page space but put the total demand above defined paging space.

The user didn't define their storage allocation, and in practice can't do th at at all. So the user didn't set up the situation which caused the integri ty issue, the system administrator did. The system administrator is in control of the CP Directory, and as such, decisions are left to him. The system doesn't question what he does, within the definition of the syntax, semantics and limitations of the directory entries and commands. If you want to define a large virtual machine, should the system question your authority? The system could check the memory and page space against each directory entry as the binary directory is built, but this would add time to the directory build, and does not account for the situation of planning to a dd more page space before logging in the new directory entry. Maybe a warni ng of User exceeds paging space could have averted this situation, b ut again, each user would have to be checked against the running system. It shouldn't keep you from creating the entry, just let you know that there might be an issue if you actually use it. To my mind, if this requires addressing, it should be in the DIRECTXA command, so as to help the system administrator in avoiding aiming the g un at his toes. -- Robert P. Nix Mayo Foundation.~.

Re: FTP Translation
You didn't mention what FTP client software you're using. Some make it easier than others, but as you know/suspect - a binary transfer is what you need.

Re: TCP/IP Hangs?
A network trace between your IP address and the TCPIP stack is an excellent place to start. Looking at the packet trace will tell you whic h end of the connection is causing the delay. It could be delays caused by conflicts between the TCPIP algorithms for Nagle and Delayed Acks (which can be intermitten based on the packets tha t need transmitting). Been there, debugged that. It could also be a problem on the PC if Windows is doing paging. Been there too.

Re: ISPF/PDF CMS MACLIB - Maintenance
Any reason you can't change the LINK mode from MW to RR? As extra insurance delete the Write and Multi-write passwords from the MDISK. Less secure, but perhaps sufficient, would be changing the ACCESS command to access the disk as an extention of another disk, thus making it R/O. Even less elegant might be putting the MACLIB on a MDISK that is full so that it can't updated even though there is a write link to it. In any scenario you'd have to see what kind of error the appliation gets when it tries to update the MACLIB and your (and your users) tolerance fo r it.

Re: Virtual vs. Physical Memory in ZVM
Windows and AIX platforms need more memory so they can buffer data in memory and avoid I/O.

I'd call it an Apples to Oranges comparison without having lots more details. We don't run WAS or Websphere, so I can't comment on if they are exceptions to the general zLinux size trimming or not.

I would question whether you really need those guests to be 6G. Our WAS 6.1 guests range from 1G-8G, with the majority of them in between 1G and 2G. The overcommittment ratio you tolerate depends heavily on the robustness of your paging subsystem. It also depends on how idle/not idle they are. At one point we had about 100 servers, about 1/2 of them WAS on 24G of real, overcommitt of maybe 5:1. That was painful (and amazing that VM ca n page in the 10's of thousands per second). But it was test/dev. We wouldn't do that to production. At the moment, I'm looking at one test system that is 2.1:1 on 44G with 38 servers up on it.

I don't understand why there is the following restriction on

There are still some programs/systems that use Julian. For instance
,
EREP requires DATE input in Julian.
Having said that, how can I compute a day 90 days in the
past, specified
in Julian (in REXX)?

Re: Vm Accounting data and DISKACNT

In order to get the whole days accounting records would I do something like issue the ACNT ALL command at lets say 11:45pm. After that since DISKACNT is running DISCONNECTED how would I invoke my exec that is going to process the accounting file from DISKACNT and send it to z/OS?

Re: What speed are my channels actually running at?
What's important is what is in the active IOCDS on your z800. Assuming that your z/OS guests do not have permissions to update the real IOCDS then it doesn't matter to you what is in their z/OS HCD config (all they'll really care about is that it agrees with what's in their virtual machine definition).

What I remember is that 3-phase current is more efficient for running motors. (I used to know why, but not any more.) I think that's why my house has 3-phase in the basement to run the washer and dryer. I never heard any reason why it would be better for running a computer. (Does a z890 include a motor?) But what do I know? I am a programmer, not an engineer. So are most of u s on this list. Ditto for me. I'm not an engineeer, but I play one in this commercial. I'd suggest you might want to ask your question somewhere that electrical engineers hang out. From an electrical standpoint I already understand that 3-phase protect s against loss of a single phase and is more effecient for large motors. Given the breadth of experience on this list I was hoping to translate that into real world experience from a z perspective. But if there isn't any difference in your cost, why do you care? Unless, as Rich suggested, 3-phase is more reliable. The monthly flat rate charged by the site housing our DR equipment is higher for 3-phase than for 1-phase, so the bean counters care. My task is to try to understand what we lose/gain with the options from a cost/benefit perspective. So far I see no big benefits to 3-phase for a z box that has dual power feeds at a site with UPS and generators. For the record, we're going with the 1-phase option for the z890. Now to finish navigating through the amperage options for an ESS-800... Brian Nielsen

On Mon, 4 May 2009 13:22:36 -0500, Bob Brown bbr...@harpercollege.edu wrote: I'm not an engineer, but I question the thought that 3-phase protects against the loss of a single phase. That's straight from the z890 Installation and Planning manual, pg 4-1: Each front end power supply is provided with phase switching redundancy. The loss of an input phase is detected and the total input current is switched to the remaining phase pair without any power interruption. Depending on the configuration input power draw, the system can run from several minutes to indefinitely in this condition. Since most single phase losses are transient which recover in seconds, this redundancy provides protection against virtually all single phase outages. Brian Nielsen
z890 power: 3 phase vs 1 phase?
We're looking at power options for a z890 in a backup datacenter. The Installation and Planning manual says that the z890 can run off either single phase or three phase power. The site cost for a three phase suppl y is more than the cost for a single phase supply. I understand what singl e and three phase power are (thanks Google), I just don't understand, and havn't been able to find, what the trade-offs/compromises are other than the cost. This leaves me unable to evaluate the cost benefit of 3 phase vs 1 phase, and hence make a recommendation. Any help would be appreciated. Reference to source material would be great. Brian Nielsen
Re: z890 power: 3 phase vs 1 phase?
On Fri, 1 May 2009 12:11:40 -0400, Rich Greenberg ric...@panix.com wrot e: Check the power needed in Kilowatts for 3ph vs 1ph. And check with the power company if a 3ph kwh (killowatt hour) costs the same or more or less than a 1ph kwh. The Installation and Planning manual lists maximum system power consumption as 4.2kW without regard to whether it is 1 phase or 3 phase. In any case, cost per kwh is not relevant since the site is charging a flat fee for the installed circuit, not for the amount of power drawn through the circuit. There are 2 references I've found in the Installation and Planning manual that 3 phase uses only 2 of the phases and the 3rd phase provides redundancy against a fault in one of the other 2 phases. Three phase seems to be an extra layer of redundancy on top of the dual power feed redundancy. Is there anything more to it than that? Brian Nielsen
