The BRU Server hardware scan hangs

Tape Library Fails to Unload or Hangs During BRU Server SCSI Scan

During BRU Server configuration, we must determine how any attached tape drives and libraries are configured on the server system. To do this, the software must load a tape into any drives within a library, wait for the drive to go to the ready state, and then unload the tape from the drive back into the library slot.

On some libraries, it is possible to tell the library to unload the tape even when the tape drive itself has not unloaded. For most libraries, one of two things will happen - the unload will timeout indicating that we must unload the tape from the drive before attempting to pick it and return it to its slot, or the library will first instruct the drive to unload the tape and then pick it automatically.

In some instances, neither of these events appear to work (the library hangs) and we need to manually intervene. The steps below cover this last situation.

In the event you cannot to kill the last scan, you will have to shutdown the server, power-cycle the library, then bring the server online once the library has finished initializing.

ATTENTION: When running a hardware scan , there needs to be a tape in slot one (1).  This tape must be a data tape, it cannot be a cleaning tape.

sudo /usr/local/bru-server/server --kill
 
After this command, you should see something like:

Sending signal to XXXX
 
Where "XXXX" is the process number for the BRU Server daemon.  This number will always change so don't worry if you see a different number every time you run a hardware scan on the BRU Server Server .  Next run:

sudo /usr/local/bru-server/server --scan
 
Once you complete this command, you should see something similar to:
[user@bruapp user]$ sudo /usr/local/bru-server/server --scan
Starting hardware scan
  Scanning for tapes and changers
     Found tape at /dev/sg0 (/dev/nst0) SONY/SDX-900V

Ejecting all tapes
  Ejecting from /dev/nst0
No autoloaders detected

Saving settings...
Done

[user@bruapp user]$
Mac users, you will see ntape0 instead of /dev/nst0 for the "Found tape at" and "Ejecting from" lines.
When this is completed (returns to a command prompt), run:

sudo /usr/local/bru-server/server
 
That's it!  The hardware scan is complete and the BRU Server backups should run without issue.  If you get any errors during this part, please contact Technical Support for further assistance.
