QLogic Corporation 2312 Looking for devices... ql2312.sys 8.1.5.60 (W2K IP) 3.01.10 TSM Name ID LUN Bus Port SSN WWN TSM mt0.0.0.2 0 0 0 2 1110177214 500308C140067006 LTO mt1.0.0.2 1 0 0 2 1110176223 500308C140067003 LTO Completed in: 0 days, 0 hours, 0 minutes, 1 seconds. 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_name 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. Chapter 16. Leveraging SAN environments 551
