This article describes how to add a new volume group to an existing resource group of an active PowerHA cluster. The first step is to add the storage to both of the nodes of the PowerHA cluster. In the case of SAN storage, please ensure that your storage administrator adds the storage to both nodes of the cluster. Then discover the newly added storage by running the cfgmgr command on one of the nodes: cfgmgr Set a PVID on all the new disks that have been discovered. Next, log in to the other node, and run the cfgmgr command on that node as well, so the disks will be discovered on the other node as well. And when you run "lspv" on the second node after running cfgmgr, you'll notice that the PVID is already set for all the discovered disks it was set on the first node.
