I had seen some hosts where in the multipath output it displays dm-7 and dm-8 but in the pvs it says dm-4,dm-5 in most cases they didn't used same naming conventions.

so i was thinking is there anyway i can check whether output of pvs dm-10 ,dm-11,dm-12,dm-13,dm-14,dm-6,dm-8,dm-9 resides on which array ?

PVCHANGE(8)						      System Manager's Manual						       PVCHANGE(8)

NAME

       pvchange - change attributes of a physical volume

SYNOPSIS

       pvchange  [--addtag  Tag]  [-A|--autobackup y|n] [-d|--debug] [-f|--force] [--deltag Tag] [--metadataignore y|n] [-h|-?|--help] [-t|--test]
       [-v|--verbose] [-a|--all] [-x|--allocatable y|n] [-u|--uuid] [PhysicalVolumePath...]

DESCRIPTION

       pvchange allows you to change the allocation permissions of one or more physical volumes.

OPTIONS

       See lvm for common options.

       -a, --all
	      If PhysicalVolumePath is not specified on the command line all physical volumes are searched for and used.

       --metadataignore  y|n
	      Ignore or un-ignore metadata areas on this physical volume.  If metadata areas on a physical volume are ignored, LVM  will  not  not
	      store metadata in the metadata areas present on this Physical Volume.

       -u, --uuid
	      Generate new random UUID for specified physical volumes.

       -x, --allocatable y|n
	      Enable or disable allocation of physical extents on this physical volume.

Example
       "pvchange -x n /dev/sdk1" disallows the allocation of physical extents on this physical volume (possibly because of disk errors, or because
       it will be removed after freeing it.
