We were doing a RAID rebuild on the node for these servers today, and that's why I was in the datacenter when the MSSQL6 server went down.
The RAID was going well in rebuild but seems that another drive in the RAID set failed. Fortunately it was a RAID1 and we can very likely get it back up rather soon, but I am going back onsite to do so now (Was working mssql6 remote now)
However we will also likely need to schedule a maintenance period to move these as a drive going offline is a bad sign of impending failure.
