I've been working with StorageTek for a while on this, but I wanted to
see if any of you have this problem. I'm running NBU 3.2 on Sun
E450/Solaris 2.6 master/media server.  At first one, but now 2 of 3
drives on the same SCSI bus will come up, but after they're used for a
little bit, they go into a DOWN state. You can bring them up, but once
they're used they go back down. I get this messages repeatedy in
/var/adm/messages:

STK has replaced the drive twice (!). Is this indicative of just a bad
cable? Bad hostbus adaptor?


Thanks,
