Rebooting Cluster Server

Shawn McConnell — Sat, 17 Dec 2005 16:26:43 GMT

I'm somewhat new to working with Serviceguard. I need to reboot the primary node of the cluster but I don't want the cluster to fail over to the secondary node. So is this what I need to do ?

1) cmviewcl -v (view the cluster)
2) cmhaltpkg -v "pkgname"
3) shutdown -r -y now

Then once the server comes up

1) cmviewcl -v (View the cluster)
2) cmrunpkg -n "pkgname"
3) cmviewcl -v

Then if I need to check that switching in enabled and enable it if need be.

cmmodpkg e "pkgname"

Thanks

Shawn

you hav eit basically all correct.
The main thing to remembr is that you verify the package switching is enabled both globally and locally on the cluster.
do:
cmviewvl -v -p

Shawn,

How many nodes do you've in your cluster environment?
If you have 2 nodes and no quorum server I think your cluster whole cluster will go down.
Before the shutdown you need to perform the following: cmhaltnode -n

When server comes up run the following first:
cmrunnode -n

GoodLuck

Shawn / Daryl -- It will depend on how he has the shutdown set up.

Generally, if you use shutdown, it will do a cmhaltnode --

If you do a REBOOT instead of a shutdown, you will be in for some trouble because you will drop the node hard.

Shutdown should work fine in most cases unless you have commented out the cmhaltnode portion for serviceguard shutdown.

Melvyn,

Thanks for the confirmation. The shutdown and reboot worked fine the way we had discussed.

Many thanks to all that replied :)

Shawn
