Did you remove the disk physically from the server without administrative action an the AIX side? Whenever you are going to remove a disk permanently from an AIX server you need to remove certain pieces of information from the system. You start with the LVM level: stop access to the filesystems, unmount the filesystems, varyoff the VG. Export the VG if you are sure that it will never return (on this particular disk). (Check exportvg and reducevg commands to find out which one applies to you) Then go on by removing the information at the device level: remove the disk's entries from the ODM with rmdev -dl. Only then remove the disk itself. Stick to this sequence as the LVM level commands depend on the ODM entries.
As to the lspv: lspv shows the disks that where available during boot time. Hence it would be better to use lsdev -Ccdisk (or from AIX 5.2 on lsdev -cdisk) to find out which disks are available in the system and whether they are active or defined.

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
