ok.. now this is odd. i got it installed and, supprising enough, got
some readings. all have a shutdown temp of 65c and the front drives
range from 42-44c while the back range from 49-51c. none ever got above
51 at any time when it was shutting down on me. may be over heating
components rather than the drive shutting itself down. i also notice
that most of the drives showed a "powered on" time of around 200k hours
while the top and bottom drives in the back showed 15-17k hours... i'm
assuming that's the amount of time the box has been on rather than
runtime of the life of the drive?

no such attachments on them.

noticing the "powered on" time discrepency i'm lead to believe that
maybe the Multipack's power supply may be the issue. not able to handle
the load?

the drives i'm using in the Multipack are from an Alpha that has the
same setup as the DEC enclosure. the drives are actually interchangable
between my other running AlphaServer 1200 and the enclosure.
the DEC has 2 "squirrel cage" fans in the back that are about 6" in
diameter. made for volume rather than speed... i'll have to do a
little more tinkering to figure this out.
thanks again. i'll let you know if the same drives work in the DEC. if
so then i'll just put the Multipack back on my Ultra 10. btw, know of a
software stripe solution (free) for Solaris 10?
