Interesting - I never thought of tpclean.

tpclean shows two in "need cleaning" status but, as I have one drive
down now, there's no correlation with the down drive.

lto2 are scsi drives connected via fc through fiber bridges. 

I've had this problem through multiple version of this OS but it's the
only Linux media server in my environment.  (We're using the native lto2
drive, too - supposed to be part of this OS).

What does tpclean -L say?

Have they ever stayed up in the past?

Do you have a fiber switched environment?

Justin.
