These are a few quick checks as part of the GTM code upgrade maintenance that will be useful. As part of the maintenance preparatory work, check the license “service check date” as per K7727
Before starting the code upgrade and after the code upgrade, the following can be utilized to check the status of the devices:
From tmsh:
(/Common)(tmos)# show sys software (/Common)(tmos)# show gtm server | grep -e "Gtm::" -e "Availability" -e "State"
From bash:
/shared/bin/big3d –v
From another client machine:
dig @<GTM1_IP> <WIP_FQDN> dig @<GTM2_IP> <WIP_FQDN>
Just after the code is upgraded, make sure to run the big3d_install commands as per K13312. This will help to make sure that all the devices run the latest big3d version.
