[OmniOS-discuss] iscsi timeouts

[David Bomba]

It looks like your NFS is dropping also  ( but then recovering ), so I wouldn't be pinning the problem solely on iscsi.

The problem could be anywhere from the network driver all the way back to the switch/cables etc. You'll need to go through each item methodically to find the root cause.
