Cannot mount volume - device offline

Question

Hi everyone,
I am trying to setup OSB on a Linux box (CentOS).
I could configure the tape library and tape drives as explained in the installation/admin guide but could not get the tape volume mounted. It keeps giving the errors:
can't mount volume in tape1 - device offline
It seems that the volume is offline. How can we get it online?
The error log for the tape drive shows:

I created a file system backup job. The backup job is pending with the status "pending resource availability".
ob> lsjob all long

ob> catxcr --level 0 7
Error: unable to open transcript for 7 - No such file or directory
Error: unable to open transcript for 7.1 - No such file or directory
I also tried to do some operations on the tape device (load, identify, import… ) but the commands take forever to finish and return with errors.
ob> lsvol library lib1 long
Inventory of library lib1:
in mte: vacant
in 1: barcode JK1112, oid 100
in 2: barcode JK1111, oid 101

in 5: vacant
in dte: vacant
ob> loadvol drive tape1 mount write force 1          > (took around 10 mins to return)
Error: can't execute command - drive didn't come online; check configuration/hardware
I could see that the drive loaded into the tape immediately after issuing the command (from the Dxi GUI) but the loadvol command returned after a long time.
The log file for the obrobotd when the above command was issued shows:
