Unity server is MCS-7925H-3.0-ECS2, 2 hard drives configured RAID-5.
Last reboot noticed there was an error that no MegaRAID was found, and in the event log was:
Event Type: Error
Event Source: IDE_RAID_SYS
Event Category: None
Event ID: 6004
Time: 12:01:32 PM
No MegaRAID IDE adapter found.
Server is working for now, but is this an indication of a pending failure? I used to be able to see the RAID configuration using the Compaq ACU but it won't connect anymore.
I had a thermal event a month ago when the A/C in the server room went out and the temp rose to +100 degrees for a couple hours. My CallManager server HDD crashed as a result of this, but everything else has been working.
