ESXi 5.5 with iSCSI boot target locks up randomly

Hi,

We're running two ESXi 5.5 hosts which boot from iSCSI targets but we're having a few issues.

Occasionally the guests become unresponsive and that's when I notice the hosts are also having an issue. The backend storage appears to be fine and fully responsive. All that I can do at this stage is poweroff the VMware hosts and let everything come up fresh. It will stay up for random amounts of time; anywhere from a few months to a few weeks before it happens again.

It happened again on Tuesday so for the first time I looked at the host logs; particularly the /var/log/vmkwarning.log where I see the following:

It looks like the iSCSI boot volume disconnected and didn't come back. Note that when you look at the ONLINE message the target looks different. It is T1 instead of T0 from the offline message (vmhba32:CH:0 T:1 CN:0:). Is this significant?

What settings should I be investigating to work out what the issues and how should I know what to change to fix it? I'm hoping to find someone who may have seen this type of issue before but any pointers would be appreciated.

Kind regards,
Tom
