    I get this message trying to access the device db:

    # dsfmgr -s
    dsfmgr: NOTE: waiting for Session Lock held by member #0. At Thu Apr 24
    16:53:41 2003
    ^C
    #

    We were trying to clean up an old device earlier but these two hwmgr
    commands just hung (not kill-able):

    # ps -ef | grep hwmgr | grep -v grep
    root 397765 397719 0.0 15:53:02 pts/1 0:00.10 hwmgr sc sc
    root 398377 397758 0.0 16:00:48 pts/2 0:00.04 hwmgr delete
    scsi -did 17
    #

    The device being deleted above is in a strange state:

    # hwmgr sh sc | grep 17
      109: 17 pine tape none 0 1 tape113
    # hwmgr sh sc -id 109 -full

      Cluster shared component has no entry in the cluster database.

    How can I clear this up w/o rebooting? Is there a lock file or
    something somewhere I can delete?
