Which physical disk is associated with a logical volume in AIX systems?

Earlier releases of GPFS allowed AIX® logical volumes to be used in GPFS file systems. Their use is now discouraged because they are limited with regard to their clustering ability and cross platform support.

Existing file systems using AIX logical volumes are, however, still supported. This information might be of use when working with those configurations.

If an error report contains a reference to a logical volume pertaining to GPFS, you can use the lslv -l command to list the physical volume name. For example, if you want to find the physical disk associated with logical volume gpfs7lv, issue:

lslv -l gpfs44lv

Output is similar to this, with the physical volume name in column one.

  gpfs44lv:N/A
