VCS cluster stop GAB

[Hector Vargas]

Hi,

I have a vcs cluster environment and I want to stop gab and llt for maintenance but I keep getting error messages when I try to unload Gab module.

It seems that VCS is not stopped.

You can't unload GAB without first stopping VCS. Stop the VCS first on local node or for the whole cluster using "hastop" as per the maintenance need.

Once VCS is stopped, run gabconfig -a to check for the ports/clients status. Run/follow the commands/instructions given against them to stop them. You can also un-register them using gabconfig -u. Then unload the GAB. Once GAB unloaded successfully, unload LTT.
