Vertical failover of Management interface?
Hello,
On the PS6110, I know that vertical failover works great on the eth0 (10 Gig iSCS) interface. I have tested this many times and when I unplug eth0 on the active CM (usually CM0), iSCSI traffic passes over to eth0 on the other CM (i.e. CM1). Works great. However, when I unplug eth1 (Management, 100 Mbps copper interface), failover to the eth1 interface on the other CM does not seem to occur. Is this by design? Is there a way to enable vertical failover for Management ports?
Thanks,
Bill

Don, a follow-up question for you. Assume we have CM0 eth0 (10 Gig) and eth1 (Mgmt) cabled to Switch 1, and CM1 eth0 and eth1 cabled to Switch 2. In the case of Switch 1 dying, iSCSI traffic transparently fails over to CM1 via vertical failover, but as you noted above, Mgmt (eth1) does not failover. Therefore it is impossible to log in to the SAN until either the switch is replaced, or an administrator performs a manual controller failover from CM0 to CM1. Is my understanding correct? DO you know if any future hardware revs in controller modules will support failover of the Mgmt interface?
Thanks,
Bill
