Re: INCREASE space on my A DISK
If you have installed DFSMS, you can enlarge a minidisk with extra space added at the end of the minidisk: - verify you have DFSMS COPY: look for DFSMS MODULE on DGTOWNER 195 (DFSMS is a free feature of z/VM, but it is not pre-installed) - update the size of the minidisk in the CP directory - run DIRMAP to check you didn't create overlaps - LINK * 191 1191 MW - DFSMS COPY A 1191 - ACCESS 1191 Z - FORMAT 1191 Z (RECOMP - CP DETACH 191 - CP DEFINE 1191 191 - ACCESS 191 A It seems scary as it involves a MW LINK , but we tested this and used it several times when we where short of disk space and large minidisks had to be expanded. Note: DFSMS COPY is much faster than a FORMAT plus COPYFILE * * fm1 = = fm2 (OLDDATA; DATAMOVE will use DFMS COPY when it is available. 2008/11/7 Dave Wade [EMAIL PROTECTED] Folks, For small minidisks I used to use DISK DUMP to store it in the spool. I know its slower and you need to be sure you don't fill the spool space, but, if you are tight on DASD space, it can be quicker... I assume this will stil work ?

Am I missing a step here? CMS can write only on the formatted area of the disk. When you extended the minidisk, the formatted area didn't change. (QUERY DISK would have shown you the same values.) To make life inconvenient, CMS FORMAT cannot extend the formatted area. Smaller, yes; larger, no. So, you need TWO disks. You need a second disk to which you can copy the contents of your A-disk. (It could another MDISK, SFS or a formatted T-disk, if you like.) Then you FORMAT your 191. Then you copy the files from t-disk (e.g.) back to your A-disk. If you have DIRMAINT installed with DATAMOVE configured, a DIRM CMDISK will cause all of that to happen for you.

When you increase minidisk space (unlike SFS filespace limits) the CMS filesystem is not updated. The typical method to increase the disk space is to allocate a NEW minidisk (e.g. 291) at a new location with the larger size, check the allocation for overlaps with DIRMAP or DISKMAP (DIRMAINT or another ESM will do that for you), only _then_ run DIRECTXA (again, an ESM will do that for you) or risk overlapping minidisk space due to a manual error. Then LINK to that new disk (not ACCESS), use the CMS command FORMAT, then LINK to the old 191, ACCESS it, and COPYFILE all the files using the (OLDDATE option. Once it's all copied, go back to delete the original 191 disk, change 291 to 191, and run DIRECTXA again (an ESM with do the DIRECTXA part). Do that a few times (losing productivity), accidentally overlay an important disk a few times (losing data), and your business case for an ESM is complete ... IF you still have a job! ;-) The point is that the FORMAT command tells the CMS minidisk filesystem how large the disk is. Telling CP (via DIRECTXA) that the disk is suddenly larger still doesn't tell CMS, nor format the added blocks on the now physically larger disk.

Re: Verify from z/VM that a Linux guest is up
When I need to XAUTOLOG an SVM (linux is just another SVM) and watch its console, I use the AUTOSCIF exec from the SCIF package at the IBM DOWNLOA DS website. This xautologs the svm and sets me as the SECUSER (secondary console user) so that I can see the messages and enter commands if necess ary. If I just need to see if an SVM is at some appropriate message (login prompt), I use the TRACK svmname CONS command (TRACK is an excellent prog ram to add to your z/VM toolbox). This will show me the last spooled CONSOLE buffer. I always have my SVMs spooling there consoles somewhere. /Tom Kern /301-903-2211 On Fri, 7 Nov 2008 10:14:26 -0500, Martin, Terry R.

But I think your approach is very tricky because it relies on the DETACH 191 preventing CMS from writing back the directory. You should also make clear that nothing else should be done between these steps since it would break the spell. And not copying the data is even faster than having DFSMS COPY do it. So my approach would be: RELEASE A ( DET LINK * 191 191 ACCESS 191 A run a pipeline that formats the new cylinders beyond the CMS formatted area FORMAT 191 A ( RECOMP This takes minimal resources since it only formats the added cylinders.

Re: Parm disks vs. MAINT 123
The IBM z/VM Operating System IBMVM@LISTSERV.UARK.EDU wrote on
11/06/2008 07:52:20 PM:
I'm seeing a strange problem with z/VM 5.4. On my 2nd level z/VM 5.4
installation system, I have the predefined PARM disks, MAINT CF1, CF2,
and CF3. I also have the predefined MAINT 123 MDISK for the 540RES
volume. The problem that I am seeing is that, originally, from MAINT, I
could not get a write link to 540RES to load the directory using
DIRECTXA and the pre-defined directory without doing a CPRELEASE A, B,
and C. I still cannot even after redefining the MAINT 123 disk to the
size of the DRCT space. CP Q ALLOC MAP shows that the directory space
is cylinders 1-20. An ICKDSF CPVOL LIST shows the following allocation:
CYLINDER ALLOCATION CURRENTLY IS AS FOLLOWS:
TYPE START ENDTOTAL
- ----
PERM 0 0 1
DRCT 1 20 20
PERM 21 38 18
PARM 39 158120
PARM 159278120
PARM 279398120
PERM 3993338 2940
so 540RES appears to be correctly allocated.
As you might imagine, this causes all kind of problems with DIRMAINT,
which I installed and enabled on the 2nd level system.
Has anyone seen anything like this before? It does not seem to
something that is related to the CP NUC because I copied CPLOAD MODULE
to my test lpar and it works as expected.
Is the real volume just a mod-3? MAINT's 123 should be defined as a
full-volume MW minidisk. If it's in the directory as mdisk 123 3390 0
3339 540res mw and the actual disk is larger, then it won't qualify as a
full-pack mini and I'd expect the results you're seeing. That is, CP
won't allow you write access to a non-full-pack disk which overlays a
STABLE link, which those to the parm disks are. Try changing the
allocation to 0 END.

Are younger-generation mainframe staffers joining your companies? Have you helped recruit any (including family members!)? How are they integrated into your data centers? Are there inter-generational issues (training, collaboration, communication, work habits, whatever)? What should employers do to smooth the process? I don't have any experience with this, save I recommended learning COBOL to my son who just graduated, but he's not interested thus far. Have you worked for younger bosses/managers? What's that been like? Are there challenges communicating mainframe benefits, mindset, practices to them? No. -- May the LORD God bless you exceedingly abundantly!

Verify from z/VM that a Linux guest is up
Hi I have written some REXX (with help from this list) to shutdown and my z/Linux guests and I also have an EXEC to XAUTOLOG them when I am ready to bring them back up. I would like to know if there is a way from z/VM to check something in the Linux guest to confirm that in fact the guest is up at least to the LOGIN PROMPT?

SWAPGEN not working for FBA
Hi I am trying to use the SWAPGEN EXEC to create a FBA SWAP file by adding it to the PROFILE EXEC of the Linux guest. However it seems to keep taking the default of DIAG. Since I do not have the DIAG drivers on my RedHat REL4 guest I need to do FBA. Here is he syntax I am using: 'SWAPGEN 900 524288 FBA' I am tracing the EXEC now to see if I spot something. BTW I do have the RXDASD MODULE on the guest. This module is required for FBA swap. Does anyone have any ideas about this?
