Re: Building kernel modules on Linux 390
Coming into this a bit late, so sorry if I missed the point... On Red Hat, there's a supplied kernel-devel package that has JUST ENOUGH of the kernel source to allow you to build third-party modules. You only really need the full source package if you're going to rebuild the kernel itself, or modules that are officially part of the source tree. They use symlinks from /usr/lib/modules/bla-bla into /usr/src/linux/kernels/bla-bla too. -Original Message- From: Linux on 390 Port [mailto:[EMAIL PROTECTED] On Behalf Of Mark Post Sent: Friday, November 30, 2007 2:20 PM To: LINUX-390@VM.MARIST.EDU Subject: Re: [LINUX-390] Building kernel modules on Linux 390 >>> On Fri, Nov 30, 2007 at 3:40 AM, in message <[EMAIL PROTECTED]>, Rob van der Heij <[EMAIL PROTECTED]> wrote: -snip- > I have a vague recollection that you also need to install the > additional packages that ship the source of assorted kernel modules > (like vmcp for example).

These days (speaking of SLE10), the kernel packages have the symlinks into /usr/src/, and all you really need is the kernel-source RPM, and your own code, to build kernel modules.

Re: Defining an LPAR on a z box to run LINUX
When we first tried Linux in an LPAR, about 3 months ago, we were concerned about this. The LPAR we were using was defined for another purpose, and had access to 12,000+ DASD devices. We went to IBM, and they recommended CIO_IGNORE. I tested that under VM, and it appeared to work, but when we tried it in the real LPAR, the kernel couldn't find ANY DASD devices. Rather than delay the test, we booted without the parm, and it came up fine, 12,000+ devices and all (they were scoped down in the module parm). It took about 5 minutes to scan them all on our z9 with Ficon. We haven't tried Linux in an LPAR again since, so I have no way to determine what went wrong. -Original Message- From: Linux on 390 Port [mailto:[EMAIL PROTECTED] On Behalf Of David Boyes Sent: Thursday, August 02, 2007 9:41 AM To: LINUX-390@VM.MARIST.EDU Subject: Re: [LINUX-390] Defining an LPAR on a z box to run LINUX > > > You should also use cio_ignore= to ignore all devices you might want > > to > > > use later but not now.

Udev should handle this automatically. Like I said in the previous note, however, it can take up to 10 seconds for the device node to appear.

In addition to what Adam said about making sure to rebuild your initrd and re-run zipl, be careful of what you've done here.

Re: PAV and RHEL 4 issue, not found on pathvec
I have device-mapper-multipath-0.4.5-16.1.RHEL4, but based on what I saw, I don't see how this can be fixed without an update to the kernel driver. The driver at the U4 level doesn't export vendor and model info into sysfs, so there doesn't appear to be any way for device-mapper-multipath to identify a rule set for dasd.

Re: PAV and RHEL 4 issue, not found on pathvec
I spent a lot of time going around with this. The problem seemed to come down to that with the kernel I'm using (2.6.9-42.0.8), the dasd driver doesn't provide vendor and model info in sysfs, so device-mapper-multipath can't match up the devices with a rule set. The newer driver in RHEL5 does provide this, and I was able to get it to work there. If someone else has found a workaround, I'd love to hear it, because we have situations where we'd love to use PAVs, and have been assuming they're not supported till RHEL5. Incidentally, the "pathvec" message seems to be semi-normal. It also shows up on our multipath FCP devices, but they do work. There's also a syntax issue with the blacklist section of the multipath.conf file, at least on RHEL5. The default blacklist includes dasd*, but there's a "blacklist exceptions" section that's supposed to override this by vendor/model code. That section is invalid unless there's a "blacklist" section, so you can't remove the blacklist entirely. You need to put SOMETHING in the blacklist, even if it's bogus. The "exceptions" bit doesn't appear to work anyway, if "dasd*' is in the blacklist, the devices won't be examined. One more problem was that the mapper uses dasdview to pull the labels from the devices, and uses the labels to match up devices. If you're using minidisks for your non-PAV devices, and you happen to have a duplicate volume label, the mapper creates a multipath group for the pair (in our case, it was / and /var), and they're marked "busy". When the script tries to mount them by base device node, the mounts fail, and the boot process stops. -Original Message- From: Linux on 390 Port [mailto:[EMAIL PROTECTED] On Behalf Of Stefan Bader Sent: Friday, June 15, 2007 7:37 AM To: LINUX-390@VM.MARIST.EDU Subject: Re: [LINUX-390] PAV and RHEL 4 issue, not found on pathvec Hi Eric, short answer: if "multipath -ll" doesn't show anything, your setup still isn't correct. Now for some more information. Is the output of "multipath -v3" that you sent complete? It sound a bit strange. If DASDs aren't blacklisted there should be some action. The "not found in pathvec" is normal for an inittial run. It just says there hasn't been any information about the paths gathered, yet.

Re: FCP - shared disk [was: RHEL 4 - FCP - tape drives]
Here's what we were told: Without NPIV, the FCP CHPID acts like a shared HBA, and all LUNS are visible to all virtual machines in all LPARs. Only one OS instance can use a given LUN, however. If another tries, the LUN will appear busy. WITH NPIV, the system assigns an arbitrary virtual WWPN to each individual address (device number/subchannel). On the storage side, the SAN admins map/mask/whatever to the virtual HBA port names. The LUNs can be mapped to multiples, so sharing LUNs is possible. To share tape drives between zLinux instances for TSM server, NPIV is required. For us, this whole business of arbitrary virtual port names has serious DR implications. That, coupled with the whole business of having to code specific WWPNs in zfcp.conf, has caused us to proceed very slowly with FCP devices in general. -Original Message- From: Linux on 390 Port [mailto:[EMAIL PROTECTED] On Behalf Of Richard Troth Sent: Tuesday, June 05, 2007 1:09 PM To: LINUX-390@VM.MARIST.EDU Subject: [LINUX-390] FCP - shared disk [was: RHEL 4 - FCP - tape drives] Sir Alan spake: > NPIV has nothing to do with sharing across LPARs. > Sharing is simply a matter of giving an multiple LPARs > access to different subchannels the same FCP chpid. I was thinking the same thing, however ... Your SAN team may need to zone or mask things differently if multiple LPARs have access to a device and you're not using NPIV. Case in point for me is one volume (one LUN, a disk) that I need to share across five VM systems, each in its own LPAR, one physical box, one CHPID (per path), one WWPN (per path). The host presents one entity to the fabric, without NPIV, so when I (try to) bring the volume on-line in another LPAR, it fails because it is busy. I don't know SAN fabric capabilities well enough to know if this is supposed to work without special tricks, or without them, or at all. I suspect that with NPIV it will work except that our SAN team would have to zone the LUN to multiple hosts. (But we want to do that eventually anyway.) It stretches the whole disk sharing thing beyond System z and z/VM and lets Sun, HP, AIX, and the rest enjoy the pain. This is disk, not tape, if that matters. -- R; -- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390 This message w/attachments (message) may be privileged, confidential or proprietary, and if you are not an intended recipient, please notify the sender, do not use or share it and delete it.

Re: RHEL 4 - FCP - tape drives
We just went through this. First, you need the lin_tape package from IBM. That has the device-specific drivers for the tape drives. You might have to find the source RPM and rebuild it to get a version that matches your kernel. The zcfp.conf file has five fields, but only three are meaningful. Here's a sample: 0.0.0a00 0x01 0x50060482d52e5d48 0x01 0x The first field is the device number, the second is meaningless, third is the WWPN of the tape drive (make sure you have your zoning right!), fourth field is also meaningless, and the last field is the LUN, which for real IBM tapes is supposedly always zero. Note that in the LUN, only the first two bytes are meaningful, so LUN 0001 would be coded as 0x0001. We were successful with real IBM drives, but when we tried an EMC VTAPE box that was supposed to emulate them, we got a kernel panic, so try defining the drives manually via SYSFS before setting up zfcp.conf, or you might end up with an unbootable system. -Original Message- From: Linux on 390 Port [mailto:[EMAIL PROTECTED] On Behalf Of Ayer, Paul W Sent: Tuesday, June 05, 2007 8:50 AM To: LINUX-390@VM.MARIST.EDU Subject: Re: [LINUX-390] RHEL 4 - FCP - tape drives Hi Ray, Yes that's what I did cd /sys/bus/scsi/devices and did an ls ... empty also a cat /proc/scsi and cat /proc/scsi/scsi is empty too. lstape is blank.

Re: Time Zone problem
The tzdata RPM is a noarch, so a version from any distro that's even close should work. I had been asked to look into this, and I was watching for the change to RHEL4, but there has never been any mention in the changelog for the package. So I did a quick search, and found out about using the zdump command. It turns out that even the tzdata-2005m package from RHEL4 update 2 has the proper definitions for 2007. It looks like they anticipated the change to the dates, and prepositioned the update. If the current RPMs are incompatible, Lea might be able to extract the tables from the package and install them manually. Alternatively, pull the latest sources from the tzdata source package, adjust the tables manually, and use zic to compile them. Zdump will tell you if you got it right. -Original Message- From: Linux on 390 Port [mailto:[EMAIL PROTECTED] On Behalf Of Post, Mark K Sent: Tuesday, January 09, 2007 11:50 AM To: LINUX-390@VM.MARIST.EDU Subject: Re: [LINUX-390] Time Zone problem One of the downsides of running an OS that's been out of support for 3 years.

Re: sles 10 install - 32 bit packages
Same thing happens on RHEL4, and it confused me at first. Shared libraries & such are installed twice, so you can run both 32 and 64 bit binaries on the 64 bit versions. The 32 bit libraries go in /usr/lib, and the 64 bit ones in /usr/lib64. This can produce some interesting problems if package builders aren't aware that 's390x' is a 64-bit arch. -Original Message- From: Linux on 390 Port [mailto:[EMAIL PROTECTED] On Behalf Of Levy, Alan Sent: Thursday, December 21, 2006 1:07 PM To: LINUX-390@VM.MARIST.EDU Subject: [LINUX-390] sles 10 install - 32 bit packages I noticed that while the software packages were being installed, there were a lot of packages that said 32 bit.

Re: Central vs Expanded Storage
Actually, in it's original form (on 3090 or 9021, IIRC), Expanded storage was physically different memory. It was slower, and therefore cheaper. As real storage got cheaper, it was positioned as a paging-avoidance mechanism until the OS could be enhanced to address more real storage. HDS used the fact that their memory was all the same, and you could move the line between types at will, as a selling point. -Original Message- From: Linux on 390 Port [mailto:[EMAIL PROTECTED] On Behalf Of Mark Perry Sent: Friday, November 03, 2006 1:42 PM To: LINUX-390@VM.MARIST.EDU Subject: Re: [LINUX-390] Central vs Expanded Storage * PGP Signed by an unknown key: 11/03/2006 at 01:42:26 PM Hi Steve, the faster option is "not to page", which is an option if you have more real memory i.e. Central storage. Paging *OUT* from Expanded Memory, if I understand correctly, requires first bringing the data into Central storage so that it can then be written to DASD. If Expanded storage offered a better paging solution then don't you think z/OS would have retained support for it? Expanded storage, I believe, originated as physically separate storage in the days before 64bit addressing. The z9 no longer has such limitations.

Sent: Thursday, November 02, 2006 11:17 AM To: LINUX-390@VM.MARIST.EDU Subject: [LINUX-390] SMART Card Problem mapping to our Linux Drives Hello, hopefully someone is doing this and can give us some pointers on what we need to do or at least where to start. Currently, we have a few Linux (SUSe SLES 8) instances running under z/VM 5.2.0 (IFL) that we use basically as file servers. We manually keep the Linux ID/PW file in sync with Windows active directory. When a Linux user is assigned an ID, it is the same as Windows, and then they are instructed to go in and change their PW to match their windows PW before attempting to map the drive/s. So, when a user logs on to the network, it is actually their active directory (I'm not sure how this all works, but believe this is the basic premise) ID and PW that is passed on to Linux-390 to map several network drives to their windows environment. Works fine - our user community is not very big, so it is easy enough to manage the Linux IDs/PWs. Problem is however, we are soon going to implement a 'Smart Card' logon process for our windows environment and it doesn't look like our current process will continue to work. Our 'smart card' IDs appear to be a 10 digit numeric + @domain name. When we test, it appears Windows passes this on to Linux to try and map the drive, and fails since it doesn't match the Linux ID/PW. We were going to try and set up an ID in Linux to match the Smart Card ID and PIN, but Linux won't allow the numeric ID. Any ideas out there, anybody else using smart card windows logon and accessing Linux-390 drives? I'm fairly new here, and not the actual Linux Admin, so if you need any more info, I'll need to go to him for more specifics.

Re: SLES vs RHEL
Okay, RHEL4 is 2.6.9-42.0.2 (can they get any more digits?) as of today's update. Looks like they're leapfrogging. My FC5 x86 machine is 2.6.17. I forget whether Red Hat said they would be going that high in RHEL5 (probably not), but if they are doing it for Intel, they'll be doing it on z. Is SLES10 for x86 out already? Is Suse still releasing x86 and z out-of-sync with each other? Red Hat releases new versions and updates for all archs at the same time. Makes it easier to keep our x86 and zSeries systems consistent. > > What's the kernel level for SLES10?

Re: SLES vs RHEL
My experience with Yast has not been good. Maybe it's better now, but when I used it, it tended to break things and hide shadow copies of configuration files where we couldn't find them, then write over our customized REAL files when we least expected. After having to fix a couple of broken systems by hand, we gave up using it. But please, no religious wars! What's the kernel level for SLES10? I thought I recalled RHEL4 was slightly higher than SLES9. Suse does seem to like ReiserFS a lot.

Re: Swap partition "filling up" on RHEL4 - NOT
This is the road I've been down before re disk-based swapping, and in principle, I agree, BUT... I can't justify that at the moment, even if it's just because 1) We have no experience with it, and 2) We're at a point in the process where we can't make major configuration changes. I also believe virtual disk requires zVM memory backing, and we're not sure we can afford that without a lot of analysis. > -Original Message- > From: Linux on 390 Port [mailto:[EMAIL PROTECTED] Behalf Of > Rich Smrcina > Sent: Wednesday, August 30, 2006 11:37 AM > To: LINUX-390@VM.MARIST.EDU > Subject: Re: [LINUX-390] Swap partition "filling up" on RHEL4 - NOT > > > If you're running under VM, make the swap devices a virtual > disk.

Re: SLES vs RHEL
All I can tell you is from our experience. When we first looked at Linux a few years back (2002 or so), Red Hat didn't have a usable s390/zSeries distribution. We started with SLES7, and moved to SLES8. It wasn't till (relatively) recently, with RHEL3 for zSeries, that Red Hat had anything worth looking at. This delay might have allowed Suse to get feet in a number of doors, and once in, they stayed. We took a "break" from Linux-on-mainframe for a while, and coming back into it, we went with Red Hat (RHEL4), mainly because our x86 Linux base uses it, and we're trying to maintain compatibility. Red Hat keeps their x86 and z distributions in sync. There are some level differences between the two, some packaging anomalies, and a few things missing on one or the other. Stability wise, I can't really say much. RHEL4 is MUCH more stable than SLES8 ever was, but it's a much newer code base, so you can't really compare. > -Original Message- > From: Linux on 390 Port [mailto:[EMAIL PROTECTED] Behalf Of > Evans, Kevin R > Sent: Wednesday, August 30, 2006 11:23 AM > To: LINUX-390@VM.MARIST.EDU > Subject: [LINUX-390] SLES vs RHEL > > > Without wishing to stir up a firestorm here, we are working on a proof > of concept project here with RHEL on z series hardware.

Swap partition "filling up" on RHEL4 - NOT
I tracked down a copy of the actual report from the performance guy, and it turns out we've been (partially) barking up the wrong tree. Sorry for the confusion. The real story is that the large swap partition DEVICE was 100% BUSY during part of the test. The original summary report said 100% FULL, so we've all been going around trying to explain that. What I now suspect was actually happening was that the memory load increased to the point that the instance started paging heavily and saturated the path to one of the swap devices. This makes a lot more sense, but the problem is still there, just a little different. We definitely have a memory constraint, so we're going to increase the memory allocation for the instance, but would it also help to use multiple small-ish swap partitions as a safety net for peak periods? (Please don't start up the debate on whether to use disk-based swap devices at all. I've been through that, and the alternatives won't fly here right now.) Right now, the busy (larger) swap device has a priority of -2, and the other (smaller) one has a priority of -1 (defaults). The load problem appeared on the larger one, implying that it was getting hit harder (far harder than the smaller partition during peak periods). I found a howto that indicates that if you set multiple partitions to the same priority, they get used "round robin", instead in in "spillover" mode, but this might not help either. If we set several partitions to equal priority, does the kernel do any kind of load balancing between partitions? It wouldn't do much good if it keeps trying to use a heavily loaded swap device.

This is consistent with what I've observed, but it's nice to have confirmation. Here's the current swap configuration: FilenameTypeSizeUsedPriority /dev/dasdd1 partition 516136 40360 -1 /dev/dasdf1 partition 1032460 11732 -2 At the request of another, I supplied /proc/meminfo in a separate post.

Swap partition "filling up" on RHEL4
We've been doing some load testing with WAS on RHEL4 under VM, and the other day something weird came up. The machine is defined with 1.3 gb. storage under zVM 5.2, and about 1.5 gb. swap space in two partitions: One about 1 gb. (dasdf), and the other about .5 gb. (dasdd) We use a product called "Teamquest" to monitor the system during the test, and as we were running, it suddently reported "dasdf" was 100% full. WAS started to choke, and analysis of a crashdump appeared to show threads hung consistent with malloc failures. We've been going around trying to figure out: 1) why we suddenly should have run out of virtual memory (if we did, because we never even got close to that before), and 2) why it was reported in this way. Does anyone know if there's anything in the swap space management mechanism that would cause Linux to fail malloc if a single swap partition fills up? Is there some kind of process affinity for paging to swap spaces?

Re: Filesystem type and re-sizing filesystems
You can resize ext2 and ext3 filesystems while mounted with ext2online. It's a standard part of RHEL4. I don't know about other distributions.

Re: Unexpectedly closing VM console breaks Linux server under z/VM
I went back and rechecked, and while the console showed CP read, the guest actually did continue to run. I made a minor, but stupid, mistake when I first tested it.

Re: Changeing system name and IP address
For SLES9, don't forget /etc/hosts, and if your subnet changed, /etc/sysconfig/network/routes. There may also be a host name in /etc/inews_mail_gateway. If you're using Postfix for mail, /etc/postfix/main.cf. You might also have to delete ssh keys in /etc/ssh. Basically, delete any file with the string "key" in the name. New versions of the keys don't seem to have the host name though, so this might not be an issue. > -Original Message- > From: Linux on 390 Port [mailto:[EMAIL PROTECTED] Behalf Of > Gianfranco Ciotti > Sent: Wednesday, May 17, 2006 10:31 AM > To: LINUX-390@VM.MARIST.EDU > Subject: Re: [LINUX-390] Changeing system name and IP address > > > Mike Lovins wrote: > > Can some give me the directions on the proper steps to > change the system > > name and the IP address of my test Linux system that is > going to replace > > a current system I am shutting down.

Re: Is it possible to move an LVM from guest to guest?
Assuming cchccwdev is a program, Red Hat doesn't have it, so here's the "manual" procedure, which should work on any distro with a 2.6 kernel. If the device is 0100, for example, then you should have a directory: /sys/bus/ccw/devices/0.0.0100/ that contains: availability cmb_enable detach_state discipline readonly block cutype devtype online use_diag if you cat the file "online", and the device is actually online, it will return a "1". To put the device offline: echo 0 > online Then you can safely detach it via VM. On the target system, the subdirectory "0.0.0100" won't appear until you attach or link device 0100 via VM. Once that's done, you echo a "1" to the "online" file to bring it on. Note that this is INDEPENDENT of the device string you pass the module in modprobe.conf. Those are devices brought online AUTOMATICALLY. Using this manual method, you can bring ANY DASD device online that is linked or attached to the guest. We use this scheme to temporarily bring the CMS 191 disk online during boot to copy off configuration files.

Re: Is it possible to move an LVM from guest to guest?
Unmount the filesystem, and run "vgexport" for the volume group. Then take the volume offline via sysfs, and detach it from the guest (This assumes you're on the 2.6 kernel. With 2.4 it's a little more complicated). Repeat the process in reverse on the other system, doing a vgimport on the other side. I'm reasonably sure I've done this successfully. It's much easier to set up an NFS share though, and leave the volume attached to one guest. > -Original Message- > From: Linux on 390 Port [mailto:[EMAIL PROTECTED] Behalf Of > Ranga Nathan > Sent: Wednesday, May 10, 2006 2:52 PM > To: LINUX-390@VM.MARIST.EDU > Subject: [LINUX-390] Is it possible to move an LVM from guest > to guest? > > > I want to set up an LVM that I can move from guest to guest.

Re: SuSE 2.2.16 kernel to test
Pre-SLES8 systems used /etc/rc.config to configure everything except routing information.

Re: Fw: [LINUX-390] GPFS
Could be. When we first looked at Levanta, back in the 03-04 time frame, I was very curious about how they did what they claimed. I'd never heard of UnionFS, and they told me that's what their product was based on: UnionFS mounts over NFS.

Re: Checking with the experts...
FTP clients and servers are supposed to handle this transparently. If you send in ASCII or "text" mode, the proper end-of-line protocol should be automatically used on the receiving system. In binary mode, of course, you're on your own. RPM packages should obviously always be sent in binary mode. I don't think the install transfers any files that need to be sent in ASCII mode (although I could be wrong). More likely, the problem with the install is the same as it is for Windows-based ftp servers: Inconsistent file name case mangling. > -Original Message- > From: Linux on 390 Port [mailto:[EMAIL PROTECTED] > Behalf Of Tim > Hare > Sent: Monday, April 03, 2006 2:52 PM > To: LINUX-390@VM.MARIST.EDU > Subject: Re: [LINUX-390] Checking with the experts... > > > Well, that may have just shot down my last guess about why > z/OS USS wasn't > working as the FTP server for SuSe install.

Either copy the file from the other image and run rpm --verify to check it, or re-install the rpm (rpm --install --force).

Re: Setting Hostname in SuSE Linux image on VM
Try running "which hostname" to make sure you're picking up the right program. On my Red Hat system, it's in /bin. (We used to run Suse, so I'm familiar with that too, I just don't have a sample Suse system anymore.) Then run rpm -qf `which hostname` to find out which package it belongs to. On Red Hat, it's net-tools. Then you can run "rpm --verify net-tools" (or whatever package you got from the step above) to confirm that the files haven't been modified. Looks to me like you've got another program called "hostname" out there somewhere, since it's that program that sets the host name in the kernel. I wrote my own scripts to configure instance-identity after cloning to avoid using Yast, which was somewhat broken in early releases, and couldn't be run from the VM console. There are only a few places where the host name is stored, and it looks like you've covered the two most important. Just for reference, the files affected are: /etc/hosts /etc/HOSTNAME /etc/ssh/*key* (multiple files. Your best bet is to delete these when the host name changes.) /etc/postfix/main.cf > -Original Message- > From: Linux on 390 Port [mailto:[EMAIL PROTECTED] Behalf Of > Ryan Stewart > Sent: Thursday, March 30, 2006 12:59 PM > To: LINUX-390@VM.MARIST.EDU > Subject: Re: [LINUX-390] Setting Hostname in SuSE Linux image on VM > > > Thanks Mike, that did work.

Re: Cannot read package from the installation media. Media error?
My guess would be you're using a Windows FTP server on your laptop, and this doesn't work. You either need to use an FTP server or NFS on Linux.

Re: Linux on Intel;
Just as an FYI on this topic, I bought some combo USB/Firewire cards at a local PC show a while back. They had no identifiable brand name that I can recall, but they came in blue boxes, and were fairly cheap ($15-$25). They DID NOT work. Using USB 2.0 with my iPod gave all sorts of errors. Firewire worked a little better, but not much. About half the time, Windows would tell me my iPod was corrupted and I should restore it to "factory settings". Yeah, right. When they did work, they were much slower than they should have been. I finally got a new motherboard with built-in USB 2.0 and Firewire and once I got the drivers settled, all of the problems went away. So stick with known brands for this. The cheap cards still seem to have problems. > -Original Message- > From: Linux on 390 Port [mailto:[EMAIL PROTECTED] Behalf Of > Gregg C Levine > Sent: Friday, February 10, 2006 12:18 PM > To: LINUX-390@VM.MARIST.EDU > Subject: Re: [LINUX-390] Linux on Intel; > > > Hello from Gregg C Levine > Let's see The only brand I can think of, that is its available > practically everywhere is Belkin.

Re: Redhat Linux 2.4.9 Hanging
I think we did report it at the time, but we were in the process of converting to SLES8 and the LVM bug was fixed in that release. Activation now fails (properly) for a given VG if all volumes in the VG aren't present.

Re: Redhat Linux 2.4.9 Hanging
This makes sense in both our and Peter's situation, since the hangs did appear to be during this phase. We actually saw two different symptoms: At later service levels (SLES8+), the hangs seemed to be more common, but on our earlier SLES7 machines, the connect of the DASD would frequently just fail. This combined with an LVM bug that caused the wrong disks to be attached to a volume group if volumes were missing, and made for some really "interesting" situations. > -Original Message- > From: Linux on 390 Port [mailto:[EMAIL PROTECTED] Behalf Of > Carsten Otte > Sent: Thursday, November 03, 2005 11:10 AM > To: LINUX-390@VM.MARIST.EDU > Subject: Re: [LINUX-390] Redhat Linux 2.4.9 Hanging > > > Hall, Ken (GTI) wrote: > > We used to see behavior like this on our SLES8 systems, > when too many images were brought up at once.

Re: Redhat Linux 2.4.9 Hanging
We used to see behavior like this on our SLES8 systems, when too many images were brought up at once. It seemed to be related to contention for the disks because we'd reboot the images independently and they'd come up fine, and never seemed to hang on individual reboots. Try staggering the autologs (insert delays, etc.) at IPL time.

Re: Dasdfmt and other potential block sizes
In the "more than you wanted to know" department, I have sitting on my semi-junk pile an old Sony Optical disk drive that came off a Sun Sparcstation clone. It uses 600 mb. optical cartridges that only support a 1024 byte sector. It was originally supported by SunOS (the precursor to Solaris), but the drivers are long lost. Only one OS has been able to properly support it: SCO OpenServer.

Re: SLES9 install stuff - more weirdness
In this case though, it's going to depend on how the installer is doing the mounts. If it's issuing a separate mount for each CD image, unless the server allows subdirectories to be mounted under a parent export, it's not going to work.

Re: SLES9 install stuff - more weirdness
Try exporting the individual subdirectories. I've run across this sort of NFS weirdness before. You can only directly mount the exported directory, not the ones under it.
