Solaris 2.6 and NFS and Qualix High Availability

Solaris 2.6 and NFS and Qualix High Availability

Hello,

We have a problem with installing Qualix High Availability software
on Solaris 2.6, the problem is:

Machine A:
hme0 interface: 111.222.333.1 production interface
qfe0 interface: 111.222.333.2 "qualix" interface
qfe1 interface: standby for 111.222.333.33

Machine B:
hme0 interface: 111.222.333.11 production interface
qfe0 interface: standby for 111.222.333.2
qfe1 interface: 111.222.333.33 "qualix" interface

When machine A failover to machine B, we want
qfe0 interface 111.222.333.2 on machine A goes to
qfe0 interface on machine B.

Machine A is an NFS client, and the Solaris uses
hme0 and wfe0 interfacce in a "round robin" fashion
for load balance. When we shutdown qfe0 interface on
machine A, it causes machine A to hung.

Is there any solution or workaround for the problem?
Thanks.

                         huh?

I thought the largest number between the dots allowed was 255, how
can you do this?

OK, I should use 11.22.33.1 in the example, but that does not solve
the problem.

The problem is: we need to shutdown an interface and yet the interface
is possibly used for NFS, and this causes machine to get hung. Due to
the way how solaris 2.6 routing mess, we can not control which interface
to use for NFS, it is all random and not logical, and Qualix can not
deal with the situation.

Actually, I believe there is a kernel tweak to fix the "routing mess",
in solaris 2.6. Sniff around the infodocs on sunsolve, ifyou have access.
(or maybe I saw iton this newsgroup. Hmmm)
