HP StorageWorks Auto Path for AIX V04.40 Installation Guide (B7949-96008, August 2004)

Operation 27
When you use an Auto Path volume group command, specify the AIX
name (for example, hdisk1) as the physical volume name. However, after
you have performed operations on the volume group, the volume name is
changed to an Auto Path name (for example, dlmfdrv1).
Do not specify any volume group other than a volume group created using
the Auto Path volume group utility commands. Doing so may cause the
volume group to become invalid.
Example Create a volume group for Auto Path:
# dlmmkvg -s 32 -y dlmvg1 dlmfdrv2 dlmfdrv3
# dlmlsvg
Invalid volume group For a volume group used by Auto Path that includes an hdisk:
# dlmlsvg -p dlmvg1
dlmvg1:

See the Hitachi Dynamic Link Manager User’s Guide for commands to
correct the condition, as well as the complete set of Auto Path (HDLM)
volume group utility commands.
