Tearing the problem apart... DVHADD3212E Unexpected RC= 3376, from: EXEC DVHSTPWC ADD LXTEST2 CONFIG This error is because there is a problem with the PW_INTERVAL_FOR_SET statement. A DIRM ADD, CHNGID, or SETPW command (ADD, in this case) attempted to set the password validity interval to a value that is higher than the interval from the PW_INTERVAL_FOR_GEN statement (2nd value). The default is 97 days. There is either a bug in the doc or a bug in the code. PW_INTERVAL_FOR_GEN is documented to have to values on it: The first value specifies the number of days a password is valid following one of the commands that set the password for a general user, the second value specifies the number of days a password is valid for a privileged user. The code doesn't do that. It assumes all users are general users as far as PW_INTERVAL_FOR_SET is concerned. I would do a DIRM CMS LISTFILE CONFIG* DATADVH * to see what configuration files are available. Then I would look in all of them for a PW_INTERVAL_FOR_SET statement. Not finding any, I would simply restart DIRMAINT. If you comment out a statement, RLDDATA won't always work since as far as it's concerned, nothing is overriding the existing value. You can just put a null value on it.

Carsten, I would suggest that if the a CCW gets CMD REJ, that the details be displayed somewhere. I mean something that says " was rejected by device ". z/VM has something called "intensive error recording mode" where it records details of UNIT CHECKs on a device. Look at the CP SET RECORD command. Linux needs something similar, perhaps.

Re: zKVM installation problem
1) format the disk with something else first. It almost doesn't matter what
- just make a real volume label on cyl 0.
2) just click all the way through the install and take the defaults
for the disk layout.
Open a PMR if that works describing what you were trying to do originally -
this is to prove to support that your environment is able to run zKVM.

Can you give Grzegorz suggestion of a preformat a try?
In case you have subscription & support, a PMR is certainly the right
thing to do to get this fixed properly.

Re: zKVM installation problem
It’s a long shot but was the disk purged or you reused an old disk with some
leftovers on it?
I’ve seen weird python errors similar to these ones (unfortunately I didn’t
keep traces to compare) in some linux distribution during the installation if I
had a “dirty disk”.
And zKVM seems to be just another linux system.
Redhat was really bad about this. It just didn’t like dirty disks even if it
claimed that it will format them (especially minidisks which just overlapped
older bigger minidisks in the past so just trash without a real partition
table).
In your trace, the error happens just one second after “formatting disks…”
message. There is no way it would have enough time to finish format.
So that’s why I popped into my mind.
I would try to format it with ickdsf or cpfmtxa before running install, just in
case.

Re: DIRM problem
What do you have for all the configuration variables that start with PW_ in your CONFIG99 DATADVH file? The expire days should be set by PW_INTERVAL_FOR_SET= according to the documentation. I'm guessing it is not the default value or at least greater than zero. But - you say you also have RACF. In that case, forget all of the PW_ settings because RACF is the one that will be managing the passwords. You set the password change interval, etc. using the RAC SETROPTS (set RACF options) command.

Re: DIRM problem
This is the reason I have re-invested in a full rewrite of ZPRO to completely eliminate any need for SMAPI. Our community objectives should be to make our systems easier to implement and maintain. Companies are not investing in the training as in the past, skills are harder to acquire, and investing in systems where increased skills will be required in the future is completely the wrong direction. I've always found SMAPI to require training and education beyond what most of the installations out there want to invest. (How many systems programmers do you know have an extra week to pull out manuals and figure all this stuff out???) SMAPI is there to provide access from outside world to run z/vm, and I've yet to find anybody using it that thinks it has anything to do with making a system easier to implement or maintain.

Re: LVM usage
Summary: Think about how and where (and by whom) the storage is to be managed. What is the pattern? YES, I am beginning to see a pattern as we discuss it.

Is this Websphere, databases, > Samba, log storage, custom application with a lot of data, anything else? Oh my personal systems, I use LVM for all filesystems except the boot volume. Once the system is up, the boot volume is out of the picture. (I maintain the kernel and related files by copying them from /boot to wherever they physically reside. But that's just me.) Last time I used LVM at work, it was primarily WAS, but also included Tomcat and/or IHS (IBM's spin on Apache) and DB2 (UDB). Backing store in that context was primarily SAN. Note what Robert Nix said about using ECKD for the backing store: you can grow your volume groups (VGs) by adding physical volumes (PVs). As Scott just noted (overlapping email) SAN volumes tend to be much larger, but even there it's common to add a PV to a VG as the needs grow and the LVs grow. > Stories about TSM and Samba are great, but this is one installation > for the site and we are speaking in terms of z/VM, right? > Maybe i need to ask additional query: do you use LVM no matter what? > For example, if you need to create one linux (maybe a bunch of them) > with webserver (it is relatively small), will you use LVM anyway? Can't say that I use LVM no matter what, but for my "big storage" it is first choice. Always. You mention web server as an example. Common use of web servers today is to sit between your users and your applications. For that, you don't need "big storage". So for a web server, I'd let VM do your volume management, doling out minidisks to such a guest. Little value in LVM there. (This is assuming you have VM behind the server. For anything *not* virtual, go with LVM.) But IF you have ANY concerns that your web servers will need more file storage, go with LVM. It won't hurt. Even without hard numbers, experience indicates that the insertion loss with LVM is no issue. Three strikes in favor of LVM: big storage, a guest with storage growth needs, anything not virtual. > DASD now can be 27 and 54GB, which is plenty of space for normal > application use (except DB).

It's a question of management. I am seeing a pattern ... a need to differentiate how much you have versus how you will manage it. Am loving the conversation.

Re: LVM usage
We use LVM on EVERY server we build, for all of the disk, with the exception of /boot, and ASM disks for Oracle. Everything else is beneath LVM. Why? Because the users never estimate their space needs sufficiently, so there is always a need to add. Because disk subsystems seldom last the life of a system, so we are constantly being asked to move data to a new subsystem, and with LVM, we can do this transparently and without an outage to the user. Because other things grow over time, and while we include some ³buffer² space, we also don¹t like our disk going unused, so we run close to the actual size needed. Because the root filesystem shouldn¹t be maxed out by a run-away user¹s home directory, /tmp file, or /var file, and with LVM we can isolate these things, without having to allocate multiple disks. LVM lets you make little disks out of big ones, a.k.a z/VM minidisks, and it also lets you make big disks out of little ones. It lets you stripe and mirror without too much of a headache. It¹s a nice, useful, lightweight management layer that takes some of the guesswork out of disk management, and keeps it all within one tool. -- Robert P.

Re: LVM usage
My experience is that LVM is almost always used -- non-LVM is rarer on zLinux.DASD sizes have grown which help limit some needs for using LVM -- but the ability to be expanded dynamically is a pretty big sell point when the goal is 'no outage required' for most shops.. One exception is probably FCP/SAN storage -- where LVM may be used less often ... Large enough spaces may be allocated on the SAN that combining devices isn't necessary.. but I still see LVM used for expandability purposes even on this storage...

Re: LVM usage
Hi Rick, Could you tell me some details, because it is not obvious for what type of services you are actually using LVM? Is this Websphere, databases, Samba, log storage, custom application with a lot of data, anything else? Stories about TSM and Samba are great, but this is one installation for the site and we are speaking in terms of z/VM, right? Maybe i need to ask additional query: do you use LVM no matter what? For example, if you need to create one linux (maybe a bunch of them) with webserver (it is relatively small), will you use LVM anyway? DASD now can be 27 and 54GB, which is plenty of space for normal application use (except DB). Is it not enough for your needs?

Re: LVM usage
Hi Sergey, Our Samba server has a 180G filesystem on Model 9 DASD. It's obviously an LVM just to get to that size. Our TSM server has a 3.2TB staging filesystem, this guest has 72 model 54 disks to build the LVM filesystem. Striping within LVM can spread IO onto multiple disks. Databases might indeed have the possibility to group disks but most applications don't have that option. DASD volumes are usually not large enough to hold the data. Especially model 3 and model 9 are too small by itself most of the time. While databases might have similar features to group disks into larger tablespaces and/or to spread IO, implementation (and therefore advantages) depend on the database in question. Some implementations might disregard the s390 features and result in poor performance and/or increased costs.

Re: LVM usage
Do you really need it? Yes! We use it all the time to do just that, and did especially on zLinux, because the physical DASD devices were fixed in size, and relatively small. We also did it because it allowed us to non-disruptively move between DASD, using the pvmove command. This allowed us to remain up through several major disk subsystem replacements, both on the zSeries boxes and on Intel based Linux servers. Anything that avoids downtime for my users, and masks infrastructure changes from them is a ³Good Thing (tm)². -- Robert P.

Re: zKVM on zpdt
Tito, I think you ran into a Linux dasd device driver problem. The issue is, that the awsckd emulator does not support (and does not advertiese) the prefix command. This is perfectly fine for a 3390 device, however Linux does issue this command on 3390. The issue has been reported and is fixed in upstream Linux. I think the bugfix needs to be backported to your level of code. As a workaround, you can bring up another linux that is either old enough for not having the bug or new enough to have the fix, and do dasdfmt on your dasd. Using the dasd (partitioning, creating and mounting filesystems) works flawless from your kernel as far as I can tell. so long, Carsten -- Carsten Otte IBM Deutschland R&D Firmware Development From: Tito Garrido To: LINUX-390@VM.MARIST.EDU Date: 02/10/2015 18:30 Subject:Re: zKVM on zpdt Sent by:Linux on 390 Port FYI: To make it work I had to format the dasds on an older Linux like RHEL6.
