Hi
I have a very frustrating problem in that I have to keep hard rebooting a newly built ESXi 5.1.0 (Kernel build 799733) host machine.
The machine is a 2 x Dual Core AMD Opteron x64 based server with 28GB RAM and 2 x 1TB local HD. ESXi is booting from a USB drive, and each HD has one VM datastore so I have DS1 and DS2 datastores.
The symptom is that after a period of low activity (guests are all up but not being asked to do much work), DS2 becomes frozen. Trying to browse the datastore just says "Searching datastore........" and all VM's on that datastore are uncontactable. It only ever affects DS2. DS1 doesn't experience the issue.
Going into the host via SSH, at this point I cannot even list the contents of the /var/log or var/vmfs/volumes directories - it just hangs.
I cannot restart the managemnt agents or reboot from the ESXi console. The only way to bring things back to life is to restart the host, at which everything is fine. VM's start and are responsive.
I have tried this but it made no difference.

I have also disabled all power saving options and IOMMU in the host BIOS.
After reboot I check vmkernel.log and can see these disk related messages logged just before the reboot

VMK_SCSI_DEVICE_BUSY = 0x8

This status is returned when a LUN cannot accept SCSI commands at the moment. As this should be a temporary condition, the command is tried again.
In vmkwarning.log I am getting a similar messages every 30 minutes

A similar story appears in http://communities.vmware.com/thread/341512 but there doesn't seem to be anything extra here to try that I haven't already.
Any ideas appreciated.
Thanks
