If you use truecopy or similar storage cloning methods ...

You have situation that source VG and destination VG have the same LVM id (that's why vgimport will fail), and the disks are presented on all nodes of SG.
Because of the same LVM id, HPUX will not import, but will warn you there are same ID's on multiple sets of disk.

That's where vgchgid comes into play, allowing you to have 'same/cloned' volume group on any of the SG cluster member.

So you clone the disks via storage method, then vgexport the cloned volume group, change the LVM ID and import.

If you just want to extend the SG clustered volume group with new luns (your case), you just extend on the node where the package is (as you did), export preview of that volume group ( -p -m -s switches, easy to remember Smilie, then on secondary node you make vgexport of that group (plain and simple no switches),mknod, vgimport using map file from primary node.
Code:
vgimport -m yourmapfile -N -s /dev/yourvolumegroup

No downtime is required for these operations.

If you are adding additional LVOLS you will need to modify the /etc/cmcluster/package/package.sh script (where package is the name of the package you are modifying).

If those luns were used on any of the cluster nodes before the above action (extending on the primary node), you will need to run pvremove on every node for specifed disk(s) (to remove LVM information).

Hope that clears things out.

Peasant.

vxdestroy_lvmroot(1M)													     vxdestroy_lvmroot(1M)

NAME
vxdestroy_lvmroot - remove LVM root disk and associated LVM volume group SYNOPSIS
vxdestroy_lvmroot [-v] [-b] lvm_root_disk DESCRIPTION
The vxdestroy_lvmroot command tears down and removes the LVM volume group associated with the specified physical disk. This is done by removing the volumes in the volume group and then removing the volume group. OPTIONS
-b Invokes the setboot command to change the primary boot disk to the VxVM root disk from which the system was booted (if the pri- mary boot disk is not already set to this disk). The alternate boot device remains unchanged. If the -v option is also speci- fied, the settings of the primary and alternate boot devices are displayed. -v Outputs verbose messages including a timestamp that indicates major operations being performed. ARGUMENTS
lvm_root_disk Specifies the device name of the LVM root disk that is to be destroyed, along with its entire volume group. EXAMPLES
This example shows the vxdestroy_lvmroot command invoked in its simpliest form: /etc/vx/bin/vxdestroy_lvmroot c5t1d0 # /etc/vx/bin/vxdestroy_lvmroot -v -b c3t0d0 Are you sure about destroying c3t0d0 (imported on VG /dev/vg02) ? YES vxdestroy_lvmroot 06:02: Tearing down /dev/vg02 on device c3t0d0 vxdestroy_lvmroot 06:02: Unmounting and removing any volumes associated with /dev/vg02 vxdestroy_lvmroot 06:02: removing logical volume /dev/vg02/lvol1 vxdestroy_lvmroot 06:02: removing logical volume /dev/vg02/lvol2 vxdestroy_lvmroot 06:02: removing logical volume /dev/vg02/lvol3 vxdestroy_lvmroot 06:02: removing logical volume /dev/vg02/lvol4 vxdestroy_lvmroot 06:02: removing logical volume /dev/vg02/lvol5 vxdestroy_lvmroot 06:02: removing logical volume /dev/vg02/lvol6 vxdestroy_lvmroot 06:02: removing logical volume /dev/vg02/lvol7 vxdestroy_lvmroot 06:02: removing logical volume /dev/vg02/lvol8 vxdestroy_lvmroot 06:02: Removing Volume Group /dev/vg02 vxdestroy_lvmroot 06:02: Removing device files in /dev/vg02 vxdestroy_lvmroot 06:02: Removing LVM Physical Volume c3t0d0 vxdestroy_lvmroot 06:02: Removing LVM Physical Volume c1t1d3 vxdestroy_lvmroot 06:02: Removing LVM Physical Volume c1t1d4 vxdestroy_lvmroot 06:02: Removing LVM Physical Volume c1t1d5 vxdestroy_lvmroot 06:03: Current setboot values: vxdestroy_lvmroot 06:03: Primary: 0/0/6/0/0.0.0 vxdestroy_lvmroot 06:03: Alternate: 0/0/1/0/0.1.0 vxdestroy_lvmroot 06:03: Making disk c0t1d0 (0/0/1/0/0.1.0) the primary boot disk vxdestroy_lvmroot 06:03: Removal of device c3t0d0, volume group /dev/vg02 was successful SEE ALSO
