mylex RAID and RedHat Linux

Greetings,

I am running a Micron (Pentium III Xeon processor) server with RedHat 9.0.
It has hardware RAID (DAC960/Mylex RAID). 2 of the drives (1 and 2) in the
array spontaneously went offline. So, I rolled to a contingency server and
ran various diagnostics and found nothing wrong with the drives or the
controller. All I had to do was go into advanced options and make them
online to restore the system drive. The system is up and I am monitoring
it.

Can anyone think of any reasons why something like this might occur?

Thanks.

Many possible things might do this. So you need to check the NVRAM log of
events in the controller (install GAM server software on the linux server
and GAM client on windows/wine-unix and use it to connect to the GAM
server and find out this information; it may also be possible to find it
out from the BIOS program but I am not very sure).
