RE: i5 LPAR resources

["Glenn Birnbaum" <gbirnba@xxxxxxx>]

Resources (other than memory and processor) for LPAR are done at the IOP
level.  You assign an IOP to an LPAR, and everything under that IOP
becomes part of that LPAR.  So, if you have an IOP with a Disk
Controller with two RAID sets, then you have to move both RAID sets and
anything else attached to that IOP to the target LPAR.  That's one
reason why with tape devices I try to only connect one tape controller
to an IOP and nothing else.  It allows movement of the tape controller
between LPARs without any other impact.

Good Luck,

Subject: i5 LPAR resources


I've been looking over the i5 LPAR redbook and have some questions about
resource allocation to a partition.

It looks like memory can be allocated in 16Mb chunks (LMB) and adjusted
as needed.

Disk however appears to assigned at the physical drive level. Can drives
in a RAID set  be assigned to different partitions ?  Or does a whole
RAID set or IOP need to be assigned to a partition ?

My interest is in configuring a small partition for test purposes.
