There is a slight difference when we deal with importvg in PowerHA(HACMP) cluster environment. We need to give additional flag “V” it’s major number .
1) First get the major number
For the volume group disk without a PVID# ls -l /dev/<volume_group_name> # to get the major number
For the volume group disk with a PVID
# ls -l /dev/applvg
crw-rw---- 1 root system 48, 0 Jul 16 23:02 applvg
Note: here "applvg" is volume_group_name
2) Importvg
# importvg -V <major_number> -y <volume_group_name> <hdisk_number>
# improtvg -V 48 -y applvg hdisk7
# improtvg -V 48 -y applvg hdisk7
