Unexpected Shutdown on Virtual Server

[zizebra]

We have a few hundreds of virtual servers working fine except for 3 virtual servers that have been giving us headaches. These servers are have been rebooting unexpectedly. and there is nothing in the event logs to suggest why they would have restarted. The last unexpected shutdown happened a few minutes ago. A closer look on the affected servers suggest that they typical fail randomly every two - three months. I can say basically these problems started way back in 2007 and have survived the upgrades that we did in this time for vmware. The long periods between the failures has made it fairly difficult to keep an eye them.

Hi,

Might be worth checking / posting the VMkernel log on the ESX box around the time of the unexpected reboot, it's located in /var/logs

Thanks

I would also speak to your SAN Team. Unexpected reboots of VM's can also be caused by the inability for the VM to locate it's disk files.

There must be some way of determining your suggestion. But so far Iam just trying to check anything that can checked. I have checked the logs but did not find any thing pointing in any direction. I am still checking logs all vmware servers. I would have expected at least other servers to have been affected, if disks could not be located. But anyway it does does hurt to check. I will report back soon
