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,
