The root cause is that the TSM Server encountered an I/O error and
placed the path offline. You should, on a regular basis, scan the
activity log for errors. When doing TSM Admin work I like to use an
activity log search string of ANR????E. This will search a period of
time for all E level messages. You can also do that for W warning
messages. Review, understand and resolve these messages.

To fix this, you will first need to update the path and place it back
online. Take note of the device information in the path as you will need
this for the update.

The I/O error may have been caused by the drive or the media. Q VOL
ACCESS=READONLY will show any volumes that have been marked read only
because of I/O errors.  If you find any you can MOVE that DATA or simply
update the volume to READWRITE. (I like to MOVE the DATA for data
reliability.) Keep an eye on (log them) future I/O errors to determine
if the drive repeats or the media volume repeats. This should help you
isolate the error.

Subject: [ADSM-L] Drive Inconsistencies

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?
