With the IBM SAN Data Gateway, cfgmgr works as usual with no special
procedures required.  The "converter" is 'invisible' to AIX and has no
drivers.

        Hmm, interesting idea. I'd too be interested to find out if it's
possible. I wonder if there might be some translation problems on TSM the
AIX side. Through the FC connection to the RS6000, it's going to need to
define multiple rmt devices. Would a standard 'cfgmgr' see the converter
and
be able to create the devices, or would they need to be manually created?

Subject: TSM and protocol converters


I'm spec'ing a new TSM server.  To avoid having to spend a fortune on a
huge server just to get the I/O slots I need to support HV Diff SCSI, I'm
thinking of using protocol converters to reduce the number of I/O slots in
the new server.

In other words, the server would provide Fibre Channel or Gigabit E or
even LV Diff SCSi but I would connect my existing libraries via their HV
Diff SCSI interfaces, with the protocol converter in the middle.

Assuming this is technically feasible (and I know there are FC to SCSI
converters) would TSM work in such an arrangement?  What would change
relative to simply plugging in a SCSI cable into the server as I have now?

Server is "pSeries" or RS/6000; TSM is currently 4.1 but the new server
would (very soon) enter service at 5.1.

Thanks in Advance,
