Error description

  • Process like Backup Storage Pool to Server-to-Server Virtual
    Volumes will hang during Query Volume or Query STGpool.  If the
    Backup Storage Pool is canceled (can takes hours to cancel), the
    Query Volume or Query STGpool will return and the TSM server
    will function normally.
    
    Customer/L2 Diagnostics:
    On both source and target servers, get output from SHOW TXNT and
    SHOW LOCK every 5 minutes before and during the hang.  Also get
    TSM server trace of SSLOCK.
    
    The following is an example of the Show Locks.
    The Holders have a lock that is not compatible with the next
    Waiter lock for the same resource:
