Yes, you are right, it was coming from SAN to VIO Server and from VIO server to LPAR

Now the SAN Connection has been removed from the PSeries Machine

and I tried to remove the DISK from VIO Server but couldn't

Code:

# lspv
hdisk0          00c7780e79838606                    rootvg          active
hdisk8          00c7780e8945b5bb                    patchtest       active
hdisk9          00c7780e8945b5bb                    patchtest       active

# lsdev -Cc disk
hdisk0 Available 09-08-00-3,0 16 Bit LVD SCSI Disk Drive
hdisk8 Available 0A-09-02     MPIO Other DS4K Array Disk
hdisk9 Available 0A-09-02     MPIO Other DS4K Array Disk



# varyoffvg patchtest
0516-062 lqueryvg: Unable to read or write logical volume manager
        record. PV may be permanently corrupted. Run diagnostics
0516-012 lvaryoffvg: Logical volume must be closed.  If the logical
        volume contains a filesystem, the umount command will close
        the LV device.
0516-942 varyoffvg: Unable to vary off volume group patchtest.

pvremove

pvremove(1M)															      pvremove(1M)

NAME

       pvremove - remove LVM data structure from a physical volume

SYNOPSIS

DESCRIPTION

       The  command  clears  the LVM data structure on a disk, so that it is no longer an LVM physical volume.	The device may then be used by the
       file system or by other volume managers.

       The operation is denied if pv_path is assigned to a volume group.  The command only clears the LVM data structure on a  disk  if  the  disk
       does not belong to a volume group.  This avoids accidentally removing a valid physical volume under a volume group.  If the physical volume
       to be removed belongs to a volume group, use the command to first remove the volume group associated with the physical volume.

   Arguments
       recognizes the following arguments:

	      pv_path	The character (raw) device path name of a physical volume.

EXTERNAL INFLUENCES

   Environment Variables
       determines the language in which messages are displayed.

       If is not specified or is null, it defaults to "C" (see lang(5)).

       If any internationalization variable contains an invalid setting, all internationalization variables default to "C" (see environ(5)).

EXAMPLES

       Remove LVM data structure on the physical volume
