Tape Library on Aix

I am having my 14 Aix 5.3 servers on bladecenters connected with my Tape Library.
I had a backup scheduled on tape library but after taking backup successfully,
Now,

Question 1:-
I wanted to restore backup but tape library could not recognize the tape and I get I/O error in TSM. I think it is not recognizing the barcode Label on tape though I think it just check in the tape blindly while backup starts. Whats your suggestion on this any solution..?

Question 2:-
Due to above issue I removed my tape drive rmt0 from TSM Server using command

#rmdev –dl rmt0

After that I wanted to reconfigure my tape library so I fired
#cfgmgr
But it does not detects my tape library rmt0
Then I restarted my tape library and issued same commands but same result
#lsdev –Cc tape
does not throw any output
Also in /dev/, rmt0 directory is absent
What can I do to reactivate my tape drives other than rebooting my server (Aix 5.3)?

Please help immediately, thanks in advance.

tcopy

tcopy(1)							   User Commands							  tcopy(1)

NAME

       tcopy - copy a magnetic tape

SYNOPSIS

       tcopy source [destination]

DESCRIPTION

       The  tcopy  utility copies the magnetic tape mounted on the tape drive specified by the source argument. The only assumption made about the
       contents of a tape is that there are two tape marks at the end.

       When only a source drive is specified, tcopy scans the tape, and displays information about the sizes of records and tape files. If a  des-
       tination  is  specified,  tcopy makes a copies the source tape onto the destination tape, with blocking preserved. As it copies, tcopy pro-
       duces the same output as it does when only scanning a tape.

       The tcopy utility requires the use of Berkeley-compatible device names. For example,

	 example% tcopy /dev/rmt/1b /dev/rmt/2b
