Everyone who owns an HMC should take a look at this. This is a potentialhttps://www14.software.ibm.com/webapp/set2/sas/f/power5cm/supportedcode.html
problem that is about to cause havoc.
Do you see that the customer has an HMC, but the firmware update policy is
set to OS Managed. So this means when he applies PTFs it will update the
FSP. Now if these are two releases (HMC and FSP) that can't communicate he
will have a problem. The policy should be set to HMC Managed, so that you
can control when the HMC and FSP get updated. I believe right now that
HMC
4.3 is not a supported combination with FSP 01SF240.
The good news is you can update the HMC without taking the system down.
Upgrades will take about at most 60 to 90 minutes, and you will have to
get
to 6.1.2 and then to 7.3.1 (Two upgrades). Don't forget to save to
Upgrade
Data to DVD.

Subject: Re: V5R4M0 upgrade - HMC as well?
Thanks. Pete had given me good counsel on this.
Pete or Rob, any WAG on the time required to move an old HMC version to
the latest and greatest? Biggest concern is the amount of time the
System i would be down. I plan to take care of the HMC upgrade first,
let the dust settle, and then go to V5R4M0. As a quick refresher the
HMC version info is:
V 4.0
Release 3.3
HMC Build level 20050114.1
MH00224
Backup/Restore fix level (02-17-2005)
FLASHLEVELS in SST show:
LS Flash Sync Enabled.
OS MANAGED
Base Level:
Side Date/Time MI Keyword PTFs (V5R3M0)

There was a most recent discussion on this. I was pointed to an
excellent
cross reference.
Keep in mind that there are three things to keep in mind:
- Version of HMC code.
- Version of FSP code. (FSP is like the old controlling partition.)
- Version of i5/os.
This reference tells you what is supported with what. In our case we had
to upgrade our HMC from V5.? to the last version of V6 currently
available. Then we upgraded our FSP code. Then we finished upgrading
our
HMC to V7.
