Equipment involved:
IBM 2108-G07 SAN Data Gateway (1)
IBM 2109-S16 SAN Switch (2)
IBM 3584 LTO Library (1 Library with 4 SCSI Drives)

Entering the "lsdev -Cc tape" command within AIX produces this output:
rmt0 Available 14-08-01-1,0 IBM 3580 Ultrium Tape Drive (FCP)
rmt1 Available 14-08-01-2,0 IBM 3580 Ultrium Tape Drive (FCP)
rmt2 Available 14-08-01-3,0 IBM 3580 Ultrium Tape Drive (FCP)
rmt3 Available 14-08-01-0,0 IBM 3580 Ultrium Tape Drive (FCP)
smc0 Available 14-08-01-0,1 IBM 3584 Library Medium Changer (FCP)
rmt4 Available 14-08-01-1,0 IBM 3580 Ultrium Tape Drive (FCP)
rmt5 Available 14-08-01-2,0 IBM 3580 Ultrium Tape Drive (FCP)
rmt6 Available 14-08-01-3,0 IBM 3580 Ultrium Tape Drive (FCP)
rmt7 Available 14-08-01-0,0 IBM 3580 Ultrium Tape Drive (FCP)
smc1 Available 14-08-01-0,1 IBM 3584 Library Medium Changer (FCP

Looking at the Gateway:
SCSI channel - 1
        Tape Device[0:0] - 8
        Medium Changer [0:1] - 9
SCSI channel - 2
        Tape Device [1:0] - 2
SCSI channel - 3
        Tape Device [2:0] - 4
SCSI channel - 4
        Tape Device [3:0] - 6

Which devices can/should I use ???
What is the relation between the Gateway (eg. Tape Device [0:0] - 8) and the
output of the "lsdev -Cc tape" command ???

thanks in advance
