SAP Note 19395 - SAPDBA/BRRESTORE:"device busy" when restoring from

Symptom:

SAPDBA or BRARCHIVE/BRBACKUP/BRRESTORE issue the message "device busy" when verifying or reloading data files on/to tape.

Cause and prerequisites

It is possible (previously observed under OSF1) that the error message "device busy" appears when the tape is fast-forwarding or rewinding because the next action already attempts to access the tape.

Solution
Change the tape access commands in the SAPDBA menu (at the call of BRBACKUP, etc.) or in profile init.sap:

"Position command" (SAPDBA menu) or profile parameter "tape_pos_cmd"
change from "mt -f $ fsf $" to "mt -f $ fsf $; sleep 5"

"Rewind command" (SAPDBA menu) or profile parameter "rewind"
change from "mt -f $ rew" to "mt -f $ rew; sleep 5"
