Paths go offline due to scsi errors on the line. The drive doesn't
actually report an error so the drive entity stays online.

Paths can go offline for a variety of reasons above and beyond drive
hardware failure.

You can just attempt to put the path back online if it is a temporary
line fault. Best to do a visual on the drive first...

Upd path TSMSRVR DRIVE05 srct=server destt=drive libr=LTO2 online=yes

Try doing an update drive online=yes to see if that takes.  Had some
drives do that in a Wiindows environment when it hit a bad tape.  TSM
would take the drive offline.

Suggestion: go check your drive, see if it has a code on the front.
My
guess is that it does.  A drive being offline (as in 'q drive') is
separate from the path ('q path') being offline.  They are related, but
independent.
Someone else probably has good technical explanation.

Hello all,

As seen below, I have a library drive (DRIVE05) that is currently listed
as On-Line within the query drive command output but listed as not
On-Line in the query path command output.  I have logged a call with IBM
support to verify the drive is functioning; however, I am curious as to
why the inconsistency?
