RSU 802 / Problem with DIRMAINT and RACF

[Florian Bilek]

Dear all,

I upgraded my test z/VM 5.4 system recently from level RSU 801 to RSU 802.

Yesterday I saw when doing a DIRM AMDISK that the RACF profile for that
minidisk is NOT created any more. However DIRMAINT doesn't signal any error.
The tasks end with RC 0. On the other hand, when creating a new user then
the respective user profile in RACF is created as usual.
So in principal the communication with RACF seems working. I didn't sow any
information that something would need to be changed in DIRMAINT
configuration.

Do you have any hints how to analyse the problem deeper? Is there some trace
possibility?
Or should I simply open an PMR?

Best regards

Hi Kris Buelens,

Is there any way to recover the data?

Dougherty, Margaret is out of the office.

Re: VDISK

[Barton Robinson]

SYSTEM as displayed by ESALPS components is not "system" as in SYSTEM VMDBLK.  "System" is 
really system totals. Which screen exactly are you looking at? (There isn't a vdisk 
storage by user display).
The ESAASPC shows all the address spaces including VDISK, and shows 'SYSTEM'.  The ESAVDSK 
just shows the active vdisks, sorted alphabetically by user, not by "largest user", and 
should NOT show "System".

Re: SFS Restore?

[Schuh, Richard]

Your best bet at restoration is to do as Kris suggests. I would not,
under any circumstances, restore directly to the corrupted file pool
from the DDR backup unless it was taken while the file pool was down and
before the corruption occurred. Even then, you would back level all
files and catalog entries that were updated between the time of the
backup and the restore. Since we are an active  24 hours per day shop,
we can never use DDR as a potential backup process for our SFS.
 
We had a problem a few years ago with a corrupted catalog block that
required the help of the support center. The block was corrupted during
a data center move and the corruption caused the system to crash
whenever any file whose catalog entry was in the corrupted block was
referenced. Getting past this one required that we send a copy of the
catalog disk to the support center so that they could craft a zap to
bypass the bad entries. It took two tries to get it right because the
first zap just handled the failing file at the time of the crashes, all
of which were during attempts to backup the same file. After bypassing
the bad block we did a filepool unload, created an all new filepool, and
did a filepool reload to the new location/disks.  
 
In short, if you open a PMR with the support center, they may be able to
perform some magic for you. Without them, we would have lost several
days of updates instead of just the 19 files that were identified as
having entries in the corrupted block.
 
 
Good Luck, 
Richard Schuh

I've never worked with SFS before. The SFS was designed and put
into 24x7 production use circa 1996. There are few trails to follow.
Presently there is a daily backup of the system plus weekly DDR's of the
volumes. Due to production I cannot shutdown for much more time than the
backup takes. I need to restore or somehow obtain a program (deleted by
a programmer), and only that file. The manuals I have found are not too
clear regarding recovery/restore of SFS. Can one file be easily obtained
from a backup?

Re: SFS Restore?

[Kris Buelens]

Your assumption may be faint.
You issue BACKUP on the SFS server's console (or CP SEND VMSERVx
BACKAUP, what is the same) do you?.  If this is the case, you only
have a backup of the SFS control data (that is, who is enrolled, which
GRANTs are given, etc), but **not** of the data residing in these SFS
files.

Re: SFS Restore?

[Quay, Jonathan (IHG)]

Unless you have a product or process that does file level backups (look in the 
list of file pool administrators for clues) you are going to be in trouble.  
Physical backups of a running SFS server are generally not of much use.

Re: SFS Restore?

[Romanowski, John (OFT)]

If your daily SFS backups were created by the FILEPOOL BACKUP command
you could use FILEPOOL FILELOAD to restore individual files.

If the daily SFS backup was created by FILEPOOL UNLOAD, you can use
FILEPOOL RELOAD to restore individual files.

Re: SFS Restore?

[Kris Buelens]

You'd need to restore the DDR backup to a new filepool user (with
exactly the same minidisk configuration, for example userid NEWSFS).
After the restore, link to the restored NEWSFS 191 and
- RENAME oldSFS DMSPARMS fm NEWSFS = =
- change the filepool ID in NEWSFS DMSPARMS to e.g. TEMPSFS
- RENAME oldfpool POOLDEF fm TEMPSFS POOLDEF =
Release and DEATCH the NEWSFS 119 and start NEWSFS up.  Then you can
isseu DIRLIST TEMPSFS:someuserid.

But, as I wrote earlier today: DDR backups taken while SFS runs, may
yield a corrupted SFS after the restore.
If you don't want to spend money on a decent backup product (like
IBM's IBM Backup and Restore Manager or CA's VM:Backup), you should
better use FILEPOOL BACKUP as backup method:
- no extra SW license
- can run while SFS is active (better: SFS must run during the backup)
- you can restore one or more files from the backup medium.
(memory is a bit rusty, it may be FILEPOOL UNLOAD instead of FILEPOOL
BACKUP to be able to restore selected files; the SFS admin manual will
guide you to the details.)

Re: SFS Restore?

The daily backup is created from the SFS system via backup. Which since it 
has no parameters associated with it, I am assuming that everything is 
backed up.

You said your weekly backups are done with DDR, you didn’t mention what 
method you use for your daily backups.
 
If you only have DDR backups, then there is no easy way to get one (or 
any) individual file(s) restored … you have to restore the DDR for *all* 
minidisks that make up the FilePool.

Re: Files corrupted on SFS

[Kris Buelens]

Now you've got CSL reason codes and can ask help for them, like this:
 HELP ROUTINES dmsrddbk (ERRORS
and look for 54000
if still not found:
 HELP ROUTINES REASCODE

Some of these PIPE messages sound really alarming.  Did you do
something special with this SFS server?  I didn't have any corrupted
SFS file since VM/ESA 1.1 (I had some on VM/SP R6, the release were
SFS appeared.
I hope you did'n take a DDR backup while SFS was active and restored
that, that's asking for corruption.

SFS has a tool to check a filepool for errors, but I don't remember
the command name.  I'd suggest you to contact SW support.
