Setup the TSM server first.
Use "lscfg -vl rmt#" to find out the serial numbers of each of the 3590
tape drives. (If you suspect that the ODM is out of synch with reality,
you can also use tapeutil to query the drive's serial number
interactively.)
(If you're running atape, and have multiple paths, you'll see multiple
occurances of each serial number.)
Each drive name and drive path as defined in TSM should correspond to a
rmt# with a unique serial number.
Drive 3590DRV1 => server path to /dev/rmt1 => drive serial number 00012345
Drive 3590DRV2 => server path to /dev/rmt2 => drive serial number 00012773
...
Drive 3590DRV6 => server path to /dev/rmt6 => drive serial number 00025129
When it comes time to setup paths for drives as seen by the storage agent,
you repeat the process.
For example, if serial number 00012345 shows up on rmt6 on the storage
agent, then you define the storage agent's path for 3590DRV1 to point to
/dev/rmt6.
The point is that the paths should point a particular drive name (3590DRV1)
to the same tape drive (serial number) on all systems.
I suspect there are considerably more elegant ways to accomplish all this,
but I haven't seen a practical example of the method yet.

I have fiber attached 3590 tape drives in a 3494 library. 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?
