Bill,
I hate to beat this... but my situationa is as follows: I have a TSM server
residing on Z/OS with an FQDN and one IP address (as far as I know). My client
has multiple NICs. We want to use a
particular GIGE card exclusively for backup/restore and the others for
applications, so we can't disable the others.
My server's IP is not on the same subnet as my client's GIGE card, so the
default route would not be over the GIGE.
QUESTIONS: 1. Do I need to statically route the client GIGE ip address to the
Server Ip address in the client's routing table?
2. Does this ensure that data coming from the server to the
client will come down that path as well. (I don't want to fall into your "I
had a client..." scenario.
thx. joe

If you use the GIGE address of the TSM server in your DSM.OPT file on the
client, then the BACKUP data will go over the GIGE card. Any data FROM the
TSM server TO the client will go out the network adapter on the TSM server
however TCPIP routing takes it. If you have multiple adapters in the TSM
server, the outbound traffic will first go the adapter that is on the same
subnet as the client. If the GIGE and client are not on the same subnet,
then the traffic will go out the default route unless you have a specific
ROUTE in effect. If you want ALL data to go in and out the GIGE card, either
disable the other adapters, or change the default route to be the GIGE
adapter.
I had a client that had in their AIX TSM server 1 10/100 card and 2 GIGE
cards ALL set to the same subnet. Backup inbound data to the TSM server came
in over the GIGE adapter, but since the 10/100 card was the default route,
all outbound traffic, and that included RESTOREs went out the 10/100. They
couldn't figure out why restores too so long.

Use a "traceroute" command from your client box to the specific ip address
you want to go into on your tsm server.
Your backups will take the same path.
That simple...

OK... now things are getting fuzzy. This was my initial concern. Can
anyone confirm exactly what one needs to do to ensure one traverses the
GIGE NIC for both inbound and outbound traffic?

tcpclientaddress only sets the initial address for the server to come in
on.... (last I remember)
beyond that, standard system/network routing takes over.
I'm still at 4.2 & 5.1 (moving to 5.2 in the next couple of months) but we
currently put route statements on the client nodes to ensure they exit out
their proper interfaces to access the tsm server(s).

This should be an easy one for most... I have a Solaris client running TSM
v5.2. It will be getting a GIGE card. What is the best/recommended way to
ensure data is traversing the GIGE card (in both
directions... outbound/inbound) if it is not set up as the default NIC on
the client. thx.
