tmsh-tcl newbie help - How to user tmsh-tcl to change the APM Policy on virtual servers

Mornin' sir!

I've got part of an answer for you - hope it helps to get the full thing to work.

The command

tmsh list ltm virtual one-line | grep apm_policy_old | awk '{print $3}'

should give you a full list of all virtual servers that contain the specific APM policy. If you then put this in a "for" loop or something similar, together with the following two commands, it should do the trick.

modify ltm virtual vs1 profiles del { apm_policy_old }

modify ltm virtual vs1 profiles add { apm_policy_new }

Be careful not to use the "replace" command in the modify option as it replaces ALL profiles, rather than just the APM profile ("replace" is short for "replace-all-with").

Alternatively, if you are unlikely to make big mistakes in your APM policy (but still want to take a policy backup in case you do), you can also make a copy of the policy before you start, and then work on the original, rather than work on the copy. This will save you the hassle of changing them over.

Hope this helps.
