FYI - had a ESXi 5.0-768111 server crash to PSOD

Ticket opened with VMware, and VMware points to logs that indicate that it was the VAAI plugin (version 2.2) that caused it.

HP confirmed that ATS locking was causing the issue, and had us disable ATS on hosts (/VMFS3/HardwareAssistedLocking)

Woah. Did VMWare say anything about it being fixed with a patch/version update?

I just moved everything to 5.1 prior to starting to present from our new v400's.

VMware's response was to say it was a Vendor supplied plug-in causing the issue - remove the Vendor's plug-in.

HP's response was to disable the ATS locking.

NOTE: As of ESXi 5.1 - the VAAI plugin is _not_ required for array's running version 3.1+ of the Inform OS. However, since one of the two arrays we have is still on 2.3.1mu2, we had it installed.

Appreciate the info. Thanks.
