Hello --
We are running a RAID 5 array using a P410i controller on a Proliant DL380 G7 server running the Windows 2008R2 operating system and SQL Server 2008 database. Several days ago, an unexpected shutdown occurred, which resulted in the mapped drives losing their assigned drive letters. That has since been corrected.
I am trying to determine the cause of the shutdown. I have already checked the Windows Event Viewer, and aside from some instances where there were problems connecting to an HP LeftHand diskarray via the iSCSI Initiator, there were no references to an event that would cause the shutdown.
My next step is checking the log files of the array controller. I have already done a diagnostics test via the array configuration utility, and there were no errors reported. I also checked the Integrated Management Log Viewer, and there was nothing apparent listed there.
What are step(s) should I take to determine what caused the shutdown, and drive letter scrambling to occur?
Thanks.
