Defining paths between Storage Agent and shared drives
Now we must match the tape drives with those ones defined on the Tivoli
Storage Manager server. We are using different operating systems—AIX for the
server and Windows 2003 for the Storage Agent. Therefore the operating system
device names for tape drives differ and we must match them according to their
serial number and WWN IDs, which are always unique. Example 16-19 shows
the serial number and WWNs of the tape drives on the AIX Tivoli Storage
Manager server.
Example 16-19 Device identification on AIX 5L
root@Atlantic /:
lsattr -El rmt0 | grep ww_nam
e
ww_name 0x500308c140467006 World Wide Port Name
root@Atlantic /:
lscfg -vl rmt0 | grep Serial
Serial Number...............1110177214
root@Atlantic /:
lsattr -El rmt1 | grep ww_name
ww_name 0x500308c140467003 World Wide Port Name
root@Atlantic /:
lscfg -vl rmt1 | grep Serial
Serial Number...............1110176223
By matching up the WWN and serial numbers from Example 16-18 on page 550
and Example 16-19, we see that the rmt0 device on AIX is mt0.0.0.2 on the
Windows machine and rmt1 matches mt1.0.0.2. These devices match the dr00
and dr01 drive and path definitions already made on the server, shown in
Example 16-3 on page 530. We may now define appropriate paths between the
Storage Agent and the shared tape drives.
