How can i replace the Commander in Aruba 3810m stack?
MbrID Mac Address Model Pri Status--- ----------------- ------------------------------------- --- ---------------1 20XXXX-75bXXX Aruba JL075A 3810M-16SFP+-2-slot S... 254 Standby2 20XXXX-763XXX Aruba JL075A 3810M-16SFP+-2-slot S... 255 Commander
Do you want to promote the Standby to the Commander? If so:
Establish a console session with the stack using a direct console cable connection, telnet or equivalent. If using the console cable, connect it to a switch other than the Commander
Enter the following command to force Commander status over to the Standby switch:
HP Stack 2920(config)#: redundancy switchover
This causes the Standby switch to take the role of the Commander and for a new Standby to be selected from the remaining member switches. The former Commander becomes a Member of the stack.
To remove the former Commander from the stack:
HP Stack 2920(config)#: stacking member <n> remove
where n is the member number of the former Commander.
Power down the removed switch.
Disconnect the stacking cables from the removed switch and from the other switches in the stack.
Taken from :
Replacing the Commander with what? ...with the very same Switch model (with the very same SKU) or with another Switch model (with different SKU)? those are relevant details.
I suggest you to read the Aruba Backplane Stacking and VSF Best Practice on ArubaOS-Switch Technical White Paper (16.08) especially the "Backplane Stack Maintenance and Troubleshooting" Chapter (particularly "Removing a Stack Member" at page 6).
Replacing the commander with New Switch.
Try to change the priority HP Switch(config)# stacking member * priority *****
and after that do the redundancy switch over
My recommendation would be to follow procedures in the guide attached to this post.
First, manually trigger a failover to the Standby:
Next, if the Commander will be replaced with the same part:
Alternatively, if the Commander will be replaced with a different part:
