RE: Question on V5R3 LPAR mode

[CWilt@xxxxxxxxxxxx]

Correct,

With v5r3 and the i5 hardware you don't have a primary partition.

Note that from what I've heard, there's a "service processor" that monitors
the system, its logical partitions and other virtualization features.

IIRC, someone said if the service process dies, so does the system.  And to
load updates, to the SP, you have to bring down the system.

I can't confirm that though.
