Link Aggregation / VCS issue

[Michael Greenberg]

Hello fellow managers! I'm afraid I need your help.

I've created a link aggregation (on Solaris 10u7) using
# dladm create-aggr -l active -d nxge0 -d nxge1 1 (thus creating aggr1).
It works fine both for fault tolerance and load balancing. However, when I unplug both cables (nxge0 and nxge1), the system doesn't realize aggr1 is down. It reports that nxge0 and nxge1's link is down, however nothing is reported on aggr1.
This prevents my VCS resources to fail over when both links fail.

Any thoughts? (both on the aggregation side and the VCS).
Thanks.
