IVM startup issue - hpvmstart just hangs!

[grahamswilson]

Hi all,

I have a very frustrating issue - something I've never seen before.

On IVM vB.04.20.05, I have 3 VMs up and running...

I created two new guests, and when I went to start the first one with the standard `hpvmstart -P NAME`, all I see is :-

(C) Copyright 2000 - 2010 Hewlett-Packard Development Company, L.P.

...and the nothing!  Nothing in any of the log files...it just sits there....

I actually stopped a previously configured guest, and now if I try and start that, I get the same thing.

Has anyone else seen this behavior?  I am really trying to avoid rebooting the host...

Any help appreciated.

There are several reasons why this might happen.  The most common would be if a critical resource assigned to the guests is non-responsive or otherwise unavailable.  For example, a disk array that is down or FC switch port that is hung and blocking access to storage could cause hpvmstart to hang. 

There is also a known problem with hpvmstart hanging that is fixed in the HPVM CORE patch for HPVM 4.2.5.

PHSS_41190:
2: Defect QXCR1001038198
The command hpvmstart may hang in msgsnd() syscall if
too many messages are left in the AMR daemon message queue.

Are you running PHSS_41190 (or later) HPVM CORE patch on this system?  If so, then you should not be subject to this known problem.  In that case you might try running tusc against the hpvmstart command to see which system call it is hanging on.  That might tell us if there is a resource hpvmstart is waiting on.

Regards,

Dave

Thanks Dave!

Installation of that patch seemed to certainly do the trick...all is well again.
