28 HP StorageWorks Auto Path for AIX: Installation Guide
Commands for operations with Auto Path volume groups
Auto Path cannot use disks that are recognized by AIX unless you take
some special measures. Auto Path provides utility commands for
operations on Auto Path volume groups.
A volume group created using the commands from Auto Path can be used
only for Auto Path. The Auto Path utility commands for operations with
Auto Path volume groups correspond to the commands executed in the
SMIT screen “HDLM Volume Group.”
You can execute Auto Path volume group utility commands from the
command line or in the SMIT screen.
The format of each Auto Path utility command is the same as the format of
the corresponding AIX command. The return values are the same as those
of the corresponding AIX commands.
The error messages and Help output for the commands from the Auto Path
volume group utility commands are the same as those of the corresponding
for AIX commands.
If you perform volume group operations on Auto Path volume groups
without using the Auto Path volume group utility commands, the volume
group may become invalid. In this case, use AIX commands to correct this
situation. (See the example.)
Recommendation Use SMIT when you use the Auto Path volume group utility commands.
When you use SMIT to select physical disks, SMIT displays only the first
physical disk registered in ODM. This allows you to easily specify the
physical disks allocated for Auto Path of the same LU, all at one time.
Related information See the Hitachi Dynamic Link Manager User’s Guide for the commands to
be used on Auto Path (DLM) volume groups.
A volume group managed by Auto Path must contain only dlmfdrvXX
designations. Do not include an hdisk definition in an Auto Path volume
group.
