When AIX scans the SCSI bus (sometimes it is fiber) it will see the next port first, then continue in port order until the end the start at port 0 and finish the scan. If you have your servers in ports 0-4 and your tape drives in the other ports they should show up in the same order each time. The same principle applies to tape drives on ISLed switches.

I am running TSM 5.3.2.0 on AIX 5.2 ML6. The WWN and Serial number of the drive is stored in the TSM DRIVE definition. The AIX device name (/dev/rmt?) is stored in the PATH definition. I am also running TSM StorageAgent on three other AIX boxes so TSM also has PATH statements connecting a drive to the appropriate rmt device on each of the storageagent boxes. Since the serial/wwn is at the drive level and the device name is at the path level, the drives have to be assigned in the same device name order on each of the boxes. I don't know of a easy way to do that. The only way I know to do that is to zone one drive at a time to each box and do cfgmgr inbetween each so I can control which drive gets which rmt. This is a major pain. Is there an easier/better way to force the drive mapping to be the same across multiple AIX machines?
