PowerHA; Import flash copy of VG?

Hey guys, wondering if this is possible to accomplish.

PowerHA SystemMirror7.1 active/passive cluster. Restored a clustered system in test and upgraded to the latest version of PowerHA. Things are working great. However in the interest of time during cut over to the new system, I was hoping to take a flash copy of the data lun (datavg) from the current production cluster and import that to the new system, however, I'm getting stuck removing hdisk1 on the restored system.

Steps to recreate on the new cluster:

Stop the cluster services on both nodes so datavg is varied off

Code:

exportvg datavg

on both nodes - success

Code:

rmdev -l hdisk1 -Rd

on both nodes - success on node2(passive) fail on node1(active)

No matter what I try I can't remove the disk on node1, getting this error.

Code:

Method error (/etc/methods/ucfgdevice):
        0514-062 Cannot perform the requested function because the
                 specified device is busy.

The PVID's are going to change with the flash copy, so my thought was to remove these from ODM on the new system and then drop that lun. Next, add the flashed lun and do:

Code:

cfgmgr
importvg -y datavg hdisk1

Any suggestions?

cmrunnode

cmrunnode(1m)															     cmrunnode(1m)

NAME

       cmrunnode - run a node in a high availability cluster

SYNOPSIS

       cmrunnode [-v] [node_name...]  [-t | -w none]

DESCRIPTION

       cmrunnode  causes  a node to start its cluster daemon to join the existing cluster.  This command verifies the network configuration before
       causing the node to start its cluster daemon.

       To start a cluster on one of its nodes, a user must either be superuser(UID=0), or have an access policy of FULL_ADMIN allowed in the clus-
       ter configuration file. See access policy in cmquerycl(1m).

       Starting  a node will not cause any active packages to be moved to the new node.  However, if a package is DOWN, has its switching enabled,
       and is able to run on the new node, that package will automatically run there.

       If node_name is not specified, the cluster daemon will be started on the local node and will join the existing cluster.

   Options
       cmrunnode supports the following options:

	      -v   Verbose output will be displayed.

	      -t   Test only. Provide an assessment of the package placement without affecting the current state of the nodes or packages. The	-w
		   option is not required with the -t option as -t does not validate network connectivity, but assumes that all the nodes can meet
		   any external dependencies such as EMS resources, package subnets, and storage.

	      node_name...
		   Start the cluster daemon on the specified node(s).

	      -w none
		   By default network probing is performed to check that the network connectivity is the same as when the cluster was  configured.
		   Any	anomalies are reported before the cluster daemons are started. The -w none option disables this probing. The option should
		   only be used if this network configuration is known to be correct from a recent check.

RETURN VALUE

       cmrunnode returns the following value:

	       0   Successful completion.
	       1   Command failed.

EXAMPLES

       Run the cluster daemon on the current node:

	      cmrunnode

       Run the cluster daemons on node1 and node2:

	      cmrunnode node1 node2

       cmrunnode was developed by HP.
