Problem with Intel RAID Controller RS3UC080


I have an RSCUC080 RAID Controller card and the arrays connected to this controller randomly disappear from the system. The arrays usually reappear after rebooting the machine, but every once in a while they do not and I have to reboot multiple times. This usually happens at least once a day and has been going on for several weeks. I did not have this problem the first several week I had this card. The controller card is still under warranty, but I wanted to see if anyone has any suggestions about what the problem could be before submitting a warranty claim.

I have the latest BIOS and firmware for all the components below including the RS3UC080.

I would see if there is any settings in BIOS to wait for each HDDs to spin up and POST. Also although you have a 1300W PSU, if 10 drives spin up at the same time, the overall current may still exceed limit. Does your backplane support spinning up the drives one by one?


The main problem I have is the arrays disappearing after the OS has booted and has been running for a while. I don't typically have an issue with the arrays immediately after a reboot although I have seen this at least once. I will have to check to see if the backplane supports spinning up the drives one by one and I will also check the BIOS settings tomorrow as you suggested.
