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.

vximportdg

vximportdg(1M)															    vximportdg(1M)

NAME

       vximportdg - import a disk group into the Veritas Volume Manager configuration

SYNOPSIS

       vximportdg daname new_dgname

DESCRIPTION

       The  vximportdg	utility  performs  a temporary import of the disk group contained on the disk device specified by daname to the disk group
       specified by new_dgname.  As the persistent disk group information is not changed within the private partition of the  affected	disk,  the
       import is only valid for the duration of the bootload or until a vxdg deport is performed.

ARGUMENTS

       daname	 Specifies  the  device name (disk access name) of one of the member disks of the disk group to be imported. The other members are
		 imported automatically.

       new_dgname
		 Specifies the disk group to be imported.

USAGE

       One reason to use the vximportdg utility is to import a second generation of the rootdg disk group so that its objects  are  available  for
       use  while a system is running on a different rootdg.  To prevent volumes on the second generation rootdg from having the same device minor
       numbers as volumes (such as rootvol) on the active rootdg, the importation assigns temporary non-conflicting device minor numbers.  If this
       occurs, vximportdg outputs warning messages detailing the mapping of the minor numbers.
