We have a problem with one of our Power6 P570 Lpar's.

This is a so called mirror lpar (no production, but used in case of a problem with one of our production lpar's) and every sunday we refresh this lpar with de mksysb from the production lpar. This is working a few months now, without any problem.

But today we encountered a problem, the mirror lpar didn't reboot last sunday. The machine is still in a 'shutting down' state and on the HMC the referencecode is D200A200 (Begin partition power down).

When we tried to do a 'shutdown immediate'  we received the following messages:

"HSCL0634: could not execute the shutdown partition operations. Refresh the interface and check whether the operation was performed. If not, try the operation again"

"HSCL1558: the operation is unavailable in the current partition state"

Is there another way to bring down that one lpar?

update:

When I look in the Reference Code History of the lpar, code D200A200 appeared at 18:11:27 yesterday evening.
In the same minute, there are lots of codes appearing until code D200C1FF appears. After that, it is quiet until 05:10:45 this morning and then code D200A200 appears again.

When I look in the reference Code History of another mirror lpar (one that is working as it should be), the same sequence appears. But in this Refenrence Code History there are lots of more Dxxxxxxx and Cxxxxxxx codes. After the appearance of these codes I can see that the kernel is being started and AIX is starting (and the normal codes 539, 538 etc are showing).

It looks like the first lpar is just hanging on code D200C1FF and after 11 hours the lpar receives another shutdown request??

Here is a current reference to a reference book giving a short explanation to the codes:
http://publib.boulder.ibm.com/infocenter/powersys/v3r1m5/topic/areai/areai.pdf

D200A200
Explanation
Begin partition power down. SRC word 3 contains the reason for the power off.
Problem determination
SRC word 3 power down reasons

    * 1: White button power down (also known as delayed power off)
    * 2: Partition requested power down
    * 3: Partition requested end of life
    * 4: System wide shutdown
    * 5: Attention link loader
    * 6: Attention MSD
    * 7: Panel function 3 requested
    * 8: Panel function 8 requested
    * 9: Panel function 22 requested
    * A: Panel function 34 requested


D200C1FF
Explanation
Hypervisor I/O reset sent successfully


Regarding the D200A200 - you will need to look at the details of the entry to see what the SRC3 argument value is. Maybe you already know.

The code you want to see (guessing) after the D200C1FF is:

D200C2FF
Explanation
Hypervisor I/O reset complete successfully



Hope this helps a bit.

Michael,

Last week we logged a call with IBM for this problem and it turned out to be a firmware problem.

Yesterday we did a firmware update and now everything is fine again.

(I am posting this with a new fbn2010 account, I changed my emailadres on my old account and didn't get any confirmation email)

By the way: old firmware was EL320_083, new one is EL350_049
