Re: Moving DASD between LPARs

Jim,

Correct. You need to IPL to DST to do the final removal - gets that last 1 or 2 percent drained off. Once that is done you must shut the partition down cold useing Service Tools 'Operator Panel Functions'.

Next steps depend on how the disks were moved. Since it appears they are on a separate RAID card so you would modify the partition profile of the test LPAR so that the IOA (and IOP if used) are no longer REQUIRED or DESIRED for this LPAR. Now you can restart the test LPAR. If the drives are on the same RAID card you would physically remove the disks at this point.

You can add the IOA(/IOP) to the production LPAR on the fly and after a few minutes you'll see the disks and can add them to this LPAR. *DO REMEMBER* to modify the profile as well or your next IPL will fail miserably. :-)

Greetings!

I have 4 disks that were in one LPAR, and were moved to the TEST LPAR prior
to my starting here, and now we want to move them back to the original
LPAR> I ran the STRASPBAL command marking those drives with *ENDALC, then I
ran the STRASPBAL *MOVDTA command. They are now at 1.2 or 1.3 % used. They
are RAID protected.

STRSST shows them as follows;

Parity Resource Hot Spare
Set ASP Unit Type Model Name Status Protection
1 573D 001 DC04 RAID-5 N
1 3 4328 074 DD015 Active
1 4 4328 074 DD014 Active
1 1 4328 074 DD016 Active
1 2 4328 074 DD013 Active
2 571B 001 DC07 RAID-5 N
1 6 4328 074 DD018 Active
1 5 4328 074 DD017 Active
1 7 4328 074 DD019 Active
1 8 4328 074 DD020 Active

I want to remove parity set 2 - disk unites 5,6,7 and 8 from the ASP, make
them available to the other LPAR and add them to the ASP there.

What steps do I need to do now? I searched the archives, and IBM InfoCenter
and didn't see the answer I need, although I'm sure it is there. Do I have
to IPL the LPAR to dedicated Service Tools to remove them from the ASP now?

The LPARs are HMC managed. The HMC is V7R3.3.0.

Thanks!

Jim
