I'm getting "hardware changed since last backup" messages. How do I fix this?

When BRU Server tells you that you need to run a hardware scan , you'll need to do the following steps in a terminal (command line) window. There are known issues on BRU Server when trying to run a hardware scan in BRU Server Console v1.2.0.  For this reason you may copy-and-paste the commands if needed.  The examples provided here are from a Linux system with a stand-alone tape drive.  Mac users, instead of /dev/nst0, you'll see ntape0.

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...

[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.
