Tivoli Storage Manager server acsls tape mount hang

Technote (troubleshooting)


A Tivoli Storage Manager server using an ACSLS library configured in conjunction with Gresham’s EDT-DistribuTAPE as an external library manager (ELM), fails to mount tapes.


There are no errors logged in the Tivoli Storage Manager server activity log. The mount operation does not complete. For example :

Process Description
Move Data
Volume TAPE01 (storage pool EDTPOOL), Target Pool FILEPOOL, Moved Files: 0, Moved Bytes: 0, Unreadable Files: 0, Unreadable Bytes: 0. Current Physical File (bytes): 8,131,713,736
Waiting for mount of input volume TAPE01 (2152 seconds). Current output volume: /myfs/myvols/0000B12C.BFS.

The QUERY MOUNT command shows :

ANR8379I Mount point in device class EDTCLASS is waiting for the volume mount to complete, status: WAITING FOR VOLUME.

Resolving the problem

Contact the External library manager support to diagnose the mount hang. In this case, the external library is Gresham’s EDT-DistribuTAPE and there was an incorrect drive mapping in the Gresham ELM.CONF configuration file.
