Our Windows 2008 R2 server running MS SQL 2008 R2 was not accessible even within the vsphere console. My only option was to power off and start up the server. The only event that I could find was the event id 1001 "BugCheck" which had the following: "The bugcheck was 0x000000d1 (0x0000000000000000, 0x0000000000000002, 0x0000000000000000, 0xfffff88001a9556b)" The Bug Check String is "DRIVER_IRQL_NOT_LESS_OR_EQUAL".
I downloaded Blue Screen View and nothing shows in the "caused by driver" column.
Any idea on what could be or where to look for the cause? This is the first time this has happened and there were no changes to the system recently.
