Errors Occur While Writing a Tape Label

ISSUE

Symptom

Errors occur while writing a tape label

Possible Causes

Most often, this occurs as a result of a timing issue in the tape drive’s firmware. The backup system performs a fast seek to the last dataset and determines that the tape has arrived before it actually has arrived.

Resolution

In order to fix this, open the UI, go to Configure > Appliances, edit Advanced > General Configuration.

Filter for “tape Commands” section.

Locate the “AdvancedTapePositioning” object and change the value from 1 to 0.

This will incur a penalty of taking longer to fast forward to an available space on tape when appending backups to a tape already prior used, but will solve some compatibility issues.
