Hello,

Firstly you need to change the package policy through - cmmodpkg

Then, you need to cmhaltnode to the passive node

You are ready to do your activity!!!

Shalom,

cmhaltnode is the command. I would run it on the passive node and specify which of the nodes is to be removed from the cluster, just to be safe.

Check out the man page for options.

Hy,

If you have no packages running on the passive node, you can check with cmviewcl, if you have any use cmhaltpkg to stop them.


Halt the cluster on the node

#cmhaltnode

Perform your Mantainance to the server.
(If you reboot your server and you have the AUTOSTART_CMCLD set to 1 in the /etc/rc.config.d/cmcluster file, the server will try to join the cluster on boot)



get the node back into the cluster

#cmrunnode -v

Dear

first check the status of the cluster

cmviewcl

for to see what are the packages running
if any package is running on the node(which one u want to remove)
halt the package
by using cmhaltpkg
then run cmhaltnode
then u can remove the node

thanks and regards
