*Add or move contents of physical volumes
- Today , virtually all disks are configured to AIX through configuration manager (cfgmgr).
- Move the contents of a physical volume:
migratepv [ -l lvname] sourcePV targetPV ..
# migratepv -l lv02 hdisk0 hdisk6
*Documenting the disk storage setup
- List the volume groups:
# lsvg
- List the disks on the system (PVID and volume group):
# lspv
- List which logical volumes are contained in each volume group:
# lsvg -l vgname
- List the logical volumes on each disk:
# lspv -l pvname
