Last night we had a problem on our p660-6H1 where one of the disks in
our mirrored pair of internal scsi disks went to 100% busy and but
iostat did not show any reads or writes. As a result the server was
unusable until we rebooted it which did in fact fix the problem. This
particular server is 4.3.3 and has 6 cpus and 8 gbs of ram running
oracle 8i.

Anyone else seen anything similar to this before on any scsi based
system?

TIA,

Matt
