Hi Kumar

To change hostname you need to configure only Admin context, so it's not important where other contexts are active or standby.

Do you have FT group for context Admin ? If yes and running config synchronization is eabled for it you need to run these commands only on ACE where Admin context is active :

hostname  

peer hostname

If you don't have FT group for Admin context (or running config synchronization is disabled for it) and it means that you have access to configuration mode in Admin context on both ACEs - in this case you  need to run these commands :

hostname  

peer hostname

On both ACEs in Admin context. They should be mirroring each other.

Hi Kumar.

You can change hostname on production ACEs, it doesn't affect them in any way. If you have HA pair and Admin context are in A/S situation too  you need to use :

hostname   - to set hostname for Active ACE

peer hostname - to set hostname for Standby ACE.

One more query, looking for command for manual failover.

ace# ft switchover   (press enter/ need to give the force also) what will happen press enter after the group id and what will happen press enter after the force option.

Hi Kumar

If everything is working there is no difference. However if situation when FT VLAN is down you won't be able to perform ft switchover without force option. (because there is no real FT at this moment). However if because of any reason you need to manually put FT group in Standby status (e.g. something happened , FT vlan is down and devices are in Active/Active state) you can use "force" and this will force device in Standby state despite that FT communication is broken
