We're using eth2 for heartbeat on our CASes as well and we also don't
have any link-detect IP set, but our CAS boxes are connected to
switch-routers that almost never get rebooted, so it's hard to say. l.
How long have you waited for the CASes to reconnect to the CAM?

Thank you for the comment. Our heartbeat interface is eth2 which is nothing to do with the switch. I was thinking of the link detect IP. We had the trust side link detect IP set to be the default gateway. When the switch reboot, both CASes in the HA pair cannot connect the the default gateway. Then I thought they may screw up. But I have tested to set the link detect IP to be N/A and still the same problem.

Subject: Re: HA CAS pair cannot reconnect to CAM after reboot the switch
I believe we have. I think what happens is that failover fails because
both are offline, and they don't know who should be active once
connection has been restored. I think YMMV depending on the type of
interface the heartbeats go through.

Our CAM/CAS are running version 4.1.6 and CAS servers are in central deployment mode. We just found if we reboot the switch(c3750 or c6506) which connect to the HA pairs, the HA CAS pairs cannot reconnect to CAM automatically(showing as "Not Connected"). The standalone CAS server can reconnect to CAM automatically without problem after the switch reboots. For the HA CAS pairs, we had to reboot the active one, then the standby one can reconnect to CAM automatically.
Has anyone seen this issue in your environment?
