*************************************************************** PowerHA/HACMP Moving Resource Group (RG) one node to other ***************************************************************

We are going to discuss about the resource group (RG) movement one node to other in PowerHA.

Here are the steps:********************

1) Extending PATH vairable with cluster paths**********************************************Sometimes cluster paths are not included in default path ,run below command incase if you are not able to run commands directly.export PATH=$PATH:/usr/es/sbin/cluster:/usr/es/sbin/cluster/utilities:/usr/es/sbin/cluster/sbin:/usr/es/sbin/cluster/cspoc

2) Check the cluster services are up or not in destination node*****************************************************************

#clshowsrv -vStatus of the RSCT subsystems used by HACMP:Subsystem Group PID Status

Status of the HACMP subsystems:Subsystem Group PID Status clcomdES clcomdES 204984 active clstrmgrES cluster 86080 active

Status of the optional HACMP subsystems:

Subsystem Group PID Status clinfoES cluster 360702 active

3) Check the availability of resource group********************************************

4) Move the resourcegroup by using below command**************************************************

==> clRGmove -g <RG> -n <node> -m

# clRGmove -g UMRG1 -n umhaserv1 -mAttempting to move group UMRG1 to node umhaserv1.Waiting for cluster to process the resource group movement request....

Waiting for the cluster to stabilize..................Resource group movement successful.Resource group UMRG1 is online on node umhaserv1.

You can use smitty path also

smitty cl_admin => HACMP Resource Group and Application Management => Move a Resource Group to Another Node / Site

5) Verify the RG movement**************************# clRGinfo-----------------------------------------------------------------------------Group Name Type State Location-----------------------------------------------------------------------------UMRG1 non-concurrent ONLINE umhaserv1  OFFLINE umhaserv2#
