First off: AIX 5.2 is at least 10 years out of support, the support for its successor 5.3 ended 2012. The support for some Power5 systems (if they have been upgraded with Power6- and Power6plus-processors) also ended beginning this year, even the Power7-support will end in September.
So, whatever you do, you should URGENTLY consider updating to anything recent.
You said the LUNs you are missing come from a FC-connected storage: did you make sure the zoning is correct? If you restored the system from an mksysb image then chances are you use another FC-adapter with a different WWPN and hence you need to modify the zones accordingly. You *do* know what "zoning" means, yes? Everything else is, i suppose, just coming from the not-found disks.
By the way: you should always give your LVs, VGs and FSes meaningful names: names like /dev/fslv00 are not meaningful and will over time contribute to the overall confusion.
I hope this helps.

vgreduce
VGREDUCE(8) System Manager's Manual VGREDUCE(8)
NAME
vgreduce - reduce a volume group
SYNOPSIS
vgreduce [-a|--all] [-A|--autobackup y|n] [-d|--debug] [-h|-?|--help] [--removemissing] [-t|--test] [-v|--verbose] VolumeGroupName [Physi-
calVolumePath...]
DESCRIPTION
vgreduce allows you to remove one or more unused physical volumes from a volume group.
OPTIONS
See lvm for common options.
-a, --all
Removes all empty physical volumes if none are given on command line.
--removemissing
Removes all missing physical volumes from the volume group, if there are no logical volumes allocated on those. This resumes normal
operation of the volume group (new logical volumes may again be created, changed and so on).
If this is not possible (there are logical volumes referencing the missing physical volumes) and you cannot or do not want to remove
them manually, you can run this option with --force to have vgreduce remove any partial LVs.
Any logical volumes and dependent snapshots that were partly on the missing disks get removed completely. This includes those parts
that lie on disks that are still present.
If your logical volumes spanned several disks including the ones that are lost, you might want to try to salvage data first by acti-
vating your logical volumes with --partial as described in lvm (8).
