Changing vcmp guest hostname?

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_hostname

If 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.
