You need the "Managing Serviceguard" manual which is available on docs.hp.com.

Shalom,

http://docs.hp.com/en/6033/HPServiceguardClusterConfig_WP.pdf

The document has a step by step configuration guide in it.

Clustering is on its most basic level using two systems with shared disk storage to provide more reliable service than can be provided by one system alone.

An important application can be configured to run on an alternate system if the main system is for any reason unavailable.

If you have a software contract with HP, you have access to the knowledge database in the ITRC.
If you have access, look for this document:
"How to decommission a Serviceguard Cluster, Package, Node or VG" ( (ID: emr_na-c00905819-6

Hi Sarwan,

Find the steps below.

To delete a package:
1. Halt the package by entering:
# cmhaltpkg -v pkg3
2. Delete the package by entering:
# cmdeleteconf -v -p pkg3

Removing a node while a cluster is running

To remove a node called nodeC when the cluster is online:
1. Ensure that all packages have been reconfigured to not include nodeC.
2. Halt the node by entering:
cmhaltnode -f nodeC
3. Gather the current cluster configuration by entering:
cmgetconf -v -C temp.ascii
4. Gather information about the removed node by entering:
cmquerycl -C clconfig.ascii -c cluster1 \
-n nodeA -n nodeB
5. Combine the two configurations in to one file (clconfig.ascii), and then apply the new
configuration by entering:
#cmapplyconf -v -C clconfig.ascii

And Dear dont forget to assign points.

Regards
Vivek
