Below provides the steps rename a virtual server, pool or any other object within the configuration of a F5 LTM. The steps provided involve the editing of the (bigip.conf) configuration file. This file is then verified for any potential issues before it is loaded and committed to the F5 LTM`s running configuration.
Backup Configuration
First of we back up the configuration.
cp bigip.conf bigip.conf.bak
Change Name
Next we amend the old object name with its new name. The -i option ensures that the changes are saved to the bigip.conf file.
sed -i ‘s/[OLD NAME]/[NEW NAME]/g’ bigip.conf
Verify Configuration
We then verfiy the configuration to ensure we don’t get any nasty surprises at the point of loading the new configuration.
b verify load
Commit Configuration
Finally we commit the new configuration to the running configuration.
b load
