I noticed this error still exists in TSM 6.3 – when an I/O error occurs that TSM is unable to access the defined drives, TSM updates the drive path offline and starts polling of the drives. Once the drive is accessible again, the drive is put back online but the drive path is left offline. To fix it, you have to manually update the path to online.

Here is a example:

tsm: TSM-SERVER>q drive
