Hi ADSM-ers!

For once in a week I have been encountering problems with the I/O errors
on volumes.ADSM mark this volumes "unavailable" and this volumes some of
them are empty and filling.When I try to move data from the ones which
are filling,the move can't work,the message is" Mount  was rejected."

Am really concerned because last time when I have to  do a restore for
one of our boxes one of the volumes could not be mounted and the restore
failed because nothing could be restored.

Can anyone help me with this problem because in future I will lose this
client and If may the problem is with the tapes,what can be done.
At the moment we using 3490Es.
