Lots of ideas on this one, it seems Toni
Harbaugh-Blackford nailed it......from his suggestion,
I added a static route on BOX1 as such::
route add -host BOX2 our_gateway_adr -dev tu1
tu1 is BOX1_NIC2. So now all comm btwn box1&2 is
nailed on NIC2, and NFS mounts are getting a better
performance now!
******Toni's Suggestion*************
Are both the interfaces on BOX1 on the same subnet?
Is BOX2 on the same subnet with BOX1? [Yes]
The only way to get around this is to set the routing
so that all
outgoing
connections from BOX1 to BOX2 go through BOX1_nic2.
The best way
to do this (without affecting anything else) is with a
static route.
The
arguments to the 'route' command depend on the ip
addresses of the
interfaces
in question.
***************************************
Many thanks to others who responded with different
ideas to try, they are namely::James Sainsbury
Copeland KCK, Rich
jay nash
Eubank, Chris
O'Brien, Pat
For others future references, I will include some
troubleshooting steps suggested:
We just disabled the embedded nic (tu0) on our as600s.
eg
ifconfig tu0 down
ifconfig tu0 delete
ifconfig tu1 alias old_tu0_ipaddress
(made permanent by editing /etc/rc.config and
/etc/inet.local.)
I think your nvram params for nic card are not set to
FastFD( you can check using:
consvar -g ewa0_mode (for interface nic1)
consvar -g ewb0_mode (for interface nic2)
If not then try to set it to FastFD (full duplex
100mbps, as i think both nic cards are same but not
set properly for 100mbps),
you can set them at bootprompt:
>> set ewa0_mode FastFD
put both interfaces in both system hosts file with
diffrerent names,
and
then mount the explicit interface you desire.
_Thanks,
Richard
