AW: GIGE NIC

Hey Joe (couldn't resist :-) )
If you - as the TSM admin - want to control the path the data takes
you have to define the TCPCLIENTADDRESS. And then you *have to* start
the GUI or CLI on the client.
When client "ABC" connects to the TSM server it tells the server the IP-Address
under wich client "ABC" can be reached.
You can omit TCPCLIENTADDRESS when each NIC is in a different subnet so the OS 
knows
how to transmit the data. But if the network guys change anything ...

That's how I unterstand it - but I could be wrong

        Typically, it's all determined by you NIC configuration on the hosts. 
TSM hands the packets off to the OS and it determines the correct path to send 
it to the other host.
        If the NICS are masked correctly, and have the correct default routes, 
you can get the host to favor any NIC. You can even go as far as configuring 
host-specific routes to make sure the correct NIC is used, but that's typically 
not necessary.

        There ~is~ an option on the TSM client of "TCPCLIENTADDRESS" that you 
can set to favor a NIC, but I haven't used it as I've always been able to get 
traffic flowing correctly at the OS level.

        The "traceroute" and "netstat" commands can be helpful in seeing which 
NIC is being used.

Subject: GIGE NIC


Situation:  have a GIGE card in one of my client nodes (SUN 5.8) running TSM 
client v 4,2,1.0 backing put to TSM server v 4,2,2.9.  Running across a GIGE 
network.  This client has multiple NICs, but
only one GIGE NIC.  In the client dsm.sys file, I've set TCPCLIENTADDRESS to 
the IP of the NIC, and TCPCLIENTPORT to 1500.

When TSM server initiates the daily backup, how does it know to connect and 
transfer data over the GIGE NIC and not the 10/100 NICS?
How is the path up to the TSM server determined?  Can I be "coming off" the 
GIGE network on my way up to the server, hence reducing my thruput?

Any suggestions would be greatly appreciated.

Regards, Joe
