RE: Moving DASD between LPARs

["Pete Massiello" <pmassiello-ml@xxxxxxxxxxxx>]

You need to IPL the partition to DST and remove the units now from the ASP.
Don't touch the raid set.

Then do a PWRDWNSYS restart(*NO) of the partition.

Now, change the partition profile to not have the RAID Controller, and for
the LPAR they are going to change that profile to add the disk controller.

Now, activate the partition we just took down (The one which is losing the
disks) and it will come up without the disk controller (and therefore
without the disks).

Then, at some point, PWRDWNSYS restart(*NO) of the partition they are going
to.

Activate that partition, and you should see 4 non configured disks (With
RAID fully configured).  Now, just add them to the ASP.  Then you can run a
STRASPBAL while the system is up.

Subject: Moving DASD between LPARs

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
