Has anyone have this problem.

When I set zfs 7420 appliance 10g interface to MTU 9000 we are getting nfs timeouts from our T4-2 solaris10 server,

1.So when set mtu to 9000 on the 7420 and then oracle user startup the oracle database we get nfs timeouts and the DB never starts

2.When we set mtu back to 1500 on the 7420 the DB then starts, we can shutdown the DB and restart ok, but when we set 7420 to mtu 9000 or anything

higher then 1500 the DB what start and we get nfs timeouts.

Heres the config
