Yeah, it wouldn't be the first time SCSI backplanes have gone bad.

Older half-height drives (like the IBM DMVS series) get REALLY REALLY HOT, and if a fan has gone out it could cause serious cooling issues. > Agreed, they're excellent machines.

Unfortunately they run a really old version of the IPMI spec, otherwise I have some scripts that can inquiry for temperature data. Maybe sometime I'll get bored and backport the stuff to IPMI 0.9. -- Doug White | FreeBSD: The Power to Serve dwhite@gumbysoft.com | www.FreeBSD.org
