Importing a new Volume Group

Accidentally importing a disk that has a root volume group can have disasterous results on your AIX system because it renames the logical-volumes required to boot your system, therefore you should know something  about a disk or disks before you attempt to import them.

Here are some handy LVM commands that help you to see what is on a disk(s) without importing:

List the maximum number of logical volumes allowed in the VG
# lqueryvg -p PVname -N

Show the PP size ?
# lqueryvg -p PVname -s

Show the number of free PPs in the VG
# lqueryvg -p PVname -F

Show the current number of LVs in the VG
# lqueryvg -p PVname -n

List the current number of PVs in the VG
# lqueryvg -p PVname -c

Display the total number of VGDAs for the VG
# lqueryvg -p PVname -D

List each LVID, LV name, state for each logical volume
# lqueryvg -p PVname -l

List each PVID, number of VGDAs and state for each PV in the VG
# lqueryvg -p PVname -P

List all the attributes with tags for the vG
# lqueryvg -p PVname -At

Show a physical volume' VGID
# lqueryvg -p PVname -v

Move a physical partition
# lmigratepp -g VGID -p old_PVID -n old_PPNum -P new_PVID -N new_PPNum
