VMM agent causing SCSI reservation conflicts on ESX hosts

Trevor Budd — Thu, 11 Jun 2009 13:25:01 GMT

We have 12 VMware ESX hosts runing ESX 3.5 U4. I am using HP Virtual Machine Management Pack 3.6 and have installed the VMM agent on all 12 hosts.

When the VMM agents are running I am seeing numerous messages in /var/log/vmkernel and /var/log/vmkwarning logs relating to failing I/O due to too many SCSI reservation conflicts.

These messages dissapear when I stop the hpvmmcntsvc service on the hosts.

I have added the VMConfigRefreshRate option to the hpvmm.conf file and set it to 300000, i.e. 5 minute poll, but the messages continue to be logged.

Has anyone else experienced this problem with the VMM agents on ESX hosts?

I have spoken to HP Support and they have advised me to download VMM version 3.7 when it becomes available during the middle of June.

I did ask whether this update addresses this specific issue but the support technician couldn't confirm this so I'm not too hopeful.
