not most efficient way but...right click /properties on each LPAR in the HMC
until you find it...
or ..if you just try to re-assign the slot using DLPAR from the HMC, it will
error and tell you where the problem LPAR is, else it will re-assign it.

I ran lsdev -Cc tape on all my LPARs but none of them showed any devices
I did see scsi devices configured on 4 of my LPARs
How do I know which LPAR is holding the drive right now?
Thanks!

off the top of my head, in a nutshell..the easiest way:
assuming the slot is setup for dlpar(meaning it is not a required slot on an
LPAR)
1. remove all child devices (rmt#/scsi#)and the slot(rmdev -dl pci#) on the
host that currently has the slot. lsdev -C|grep 'the location code' will
help.
2. on the hmc, right click on the adapter in the lpar, and select dlpar.
3. remove the slot from the lpar (via the hmc)
4. add the slot to the next lpar (via the hmc)
5. run cfgmgr on the lpar that rec'vd the slot
6. run your mksysb
7. repeat
if you forgot to remove a child device, step 3 will tell you the device that
is causing the problem

Subject: LPAR and tape drive
This may be a bit of an impossible question, but here goes....
I have just been given the task of creating mksysb on each of
7 LPARs on a p690....
(The guy that usually does this is away)
I have an Ultrium tape drive that is somehow connected to the
690 via scsi.
I've done this before but my memory is scetchy...
Could someone point me to some documentation on how to
switch the tape device from 1 LPAR to the next?
Thanks for your help!
