CirrostratusChanging vcmp guest hostname?
Hi all,
I have a vcmp host with 3 guests of which I want to change the hostname. I know it´s doable from the guest gui under platform, but when upgradring it reverts back to the vcmp host configured one. So I want to change that, can i do that straight up without changing state of the guest or do i need to change the state of the guest?
For procedures and more information, refer to K84630501: Change the BIG-IP system host name for a vCMP guest.

kimhenriksenI´ve read that one, and as it doesnt specify that i need to change the deployment state of the vcmp i guess it´s not needed.

Thank you!
Without testing on an actual vCMP system, the conventional wisdom is that modifying a guest's hostname from the host (using the TMSH command shown) should not require (nor cause) a state change on the guest.
Checking....
There is a TMSH command you can run from the command line on the vCMP host to modify the guest's hostname:
modify /vcmp guest my_guest hostname new_guest_hostnameIf you need to modify the actual guest name on the host (rather than the guest's hostname), you might try this article: https://devcentral.f5.com/s/question/0D51T00006i7YVs/how-to-rename-a-vcmp-guest It's old (2014) but... Keep in mind that you do have to reload the config on the host though, which temporarily disrupts traffic processing.

Thanks, do you know if I need to change the state of the guest before doing this. The change itself I know how to do.
