Before the drives can be used in a “swap set”, they need to be setup or intialized.Use minicom to access the Coriad via serial:
[root@backup ~]# minicom
Welcome to minicom 2.00.0
OPTIONS: History Buffer, F-key Macros, Search History Buffer, I18n

Issue the Coraid show command in the minicom terminal window:
SATA shelf 1> show -l

Issue the jbod Coraid command in the minicom terminal window:
SATA shelf 1> jbod 1.0-3
making 0
making 1

Issue the list Coraid command to verify the jbod creation:
SATA shelf 1> list -l

Mount the volume
[root@backup ~]# mount /dev/pool0/vol1 /mnt/vol1
Rsync the backuppc config files
rsync -av -v /home/config/ /home/backuppc/
Note: If you get the following error: rsync: mkdir “/home/backuppc” failed: File exists (17), recreate the link from /home/backuppc to /mnt/vol1/backuppc.
Start BackupPC
[root@backup home]# /mnt/vol1/backuppc/backuppc start
Starting BackupPC: [ OK ]
