Unloading LLT and GAB and removing VCS on the leaving node

Perform the tasks on the node leaving the cluster.

 To unconfigure and unload LLT and GAB and remove VCS

1. Unconfigure GAB and LLT:

   # /sbin/gabconfig -U

   # /sbin/lltconfig -U

2. Unload the GAB and LLT modules from the kernel.
   • Determine the kernel module IDs:

     # modinfo | grep gab

     # modinfo | grep llt

     The module IDs are in the left-hand column of the output.

   • Unload the module from the kernel:

     # modunload -i gab_id

     # modunload -i llt_id

3. Rename the startup files to prevent LLT, GAB, or VCS from starting up in the future:

   # mv /etc/rc2.d/S70llt /etc/rc2.d/s70llt

   # mv /etc/rc2.d/S92gab /etc/rc2.d/s92gab

   # mv /etc/rc3.d/S99vcs /etc/rc3.d/s99vcs

4. To determine the packages to remove, enter:

   # pkginfo | grep VRTS

5. To permanently remove the VCS packages from the system, use the pkgrm command. Start by removing the following packages, which may have been optionally installed, in the order shown:

   # pkgrm VRTScscm

   # pkgrm VRTSvcsw

   # pkgrm VRTSweb

   # pkgrm VRTScscw

   # pkgrm VRTScssim

   # pkgrm VRTScutil

   # pkgrm VRTSjre

   # pkgrm VRTSvcsdc

   # pkgrm VRTSvcsmn

   # pkgrm VRTSvcsag

   # pkgrm VRTSvcsmg

   # pkgrm VRTSvcs

   # pkgrm VRTSvxfen

   # pkgrm VRTSgab

   # pkgrm VRTSllt

   # pkgrm VRTSat

   # pkgrm VRTSperl

6. Optionally, you can remove the infrastructure packages in the order shown:

   # pkgrm VRTSvlic

   # pkgrm VRTScpi

7. Remove the VCS patch.

   # patchrm 117499-02

8. Remove the LLT and GAB configuration files.

   # rm /etc/llttab

   # rm /etc/gabtab

   # rm /etc/llthosts
