    ​Enter 'q reply' and see if it is waiting on a response for something. 

    Also, query your activity log to find out what exact tape it is waiting on.  Is that tape already in use elsewhere?

    Is the VIO or the library door full or left open? 

    It is possible that if this has been hung for a long time, you may have to restart the TSM server to refresh the library.

    Hi Prem,

    Seems odd that you have 2 library managers and 1 library client? Does each library manager manage a dedicated library partition?

    Could you check the library and drive paths (q path) on each TSM server, managers and clients.
    And also do a 'q drive' to check the drive status.

    Thank  you now issue is fixed it is very strange for me as well 2 library manager but what is the justification we received from incumbent is all Sap backup is on one library and all another backup on 1 library manager. where we have LTO5 for sap backup and LTO3 for all other backup.
