Re: Question on V5R3 LPAR mode

[Neil Palmer/DPS <neilp@xxxxxxxxxxx>]

No primary partition on V5R3.  Think of the "Service Processor" as the 
Hypervisor.  You require the HMC (Hardware Management Console - a hardened 
Linux xSeries) to manage the system with LPAR, but even if that fails it 
won;t stop the system (just stop you making certain LPAR configuration 
changes until it's back up).

Question on V5R3 LPAR mode






Me again, the know-nothing newbie that MAY be getting an iSeries.

This is a question on running in LPAR mode. One of the other guys here is
reading a RedBook about Performance Management on the iSeries. It said
something about Primary and Secondary Partitions. In particular, it said
that you have one "Primary" partition. If the OS in that partition fails,
then all other partitions fail.

Looking at the V5R3 stuff, so far, it appears that this is no longer true.

So: with i5/OS V5R3, is there a "Primary Partition", an outage on which 
will
terminate the systems in all other partitions? This is definately 
different
than zSeries where the hypervisor does not depend in any way on any LPAR.

Inquiring minds want to know <grin>.
