NimbostratusFailover detection in VCMP environmeent 5250V
Hello,
I have a 2x5250V (VCMP). I have installed two guests (Prod1 and Dev) on first host, and one guest (Prod2) on second host. These Guests are connected on the same Vlans A (for HA) & B (for VS). Prod1/Prod2 guests are in failover active/active.
When I shutdown the physical port-channel on the switch, the Gests (Prod1 and dev) become isolated regarding the vlan A & B (The trunk is down). Management Vlan still up and Guest Prod1 & Prod2 can communicate.
The active traffic groups located to Prod1 don't switch to standby status and the application does not work properly. All traffic-groups should switch and should be active on Prod2 only because Prod1 is isolated. The Vlan Failsafe feature can't help because even if the trunk is down on Guests, Prod1 and Dev can communicate (ARP traffic).
How can I do to force the traffic groups to switch to the neighbord (Prod2)?
Thank you

You may consider to put Prod1 force offline to make sure Prod2 take all traffic.

Hello,
Production and HA Vlan use the 4 TMM interfaces (RJ45) in trunk mode. I would have like to use Serial (hard-wired) failover port but in VCMP design it seems to doesn't work.
Until the management still up, the traffic-group are not active/active both side.

Hello, HA group is working well but in Active/standby model. Mine is Active/active.
