Re: Moving DASD between LPARs

[William.Epperson@xxxxxxxxxxxxxxxxxxxxxxxx]

Yes you're going to need to IPL the system into DST and remove the disks there.  Don't make the selection of ending parity before removing them, it'll
take forever and still wont remove them.  Just select to remove the entire parity set in the first place.  It'll drop the parity set once it's removed
that last bit of info and remove the disks out of the profile.  Can't remember the exact numbers for the selections.

Good luck,

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
