hmm... somehow the things you state do not add up to a coherent picture.
You can use the "lsattr -El <device>" command to get more information about a device - such as a disk. If your concern is that the SSD disks are visible at all to the system, then this is the way to go. Notice, though, that you will only see directly connected disks this way. What you have shown is a "virtual SCSI" device. I suppose your LPAR got it from a VIOS. You will not be able to see the properties of the physical disk from the LPAR in this case, because it gets the disk without caring where it comes from (just like a file doesn't care what the filesystem it resides at is made from). You will have to log on to the VIOS (or whatever exports the disk - SAN fabric, ...) and look there.
If you have made sure there is a SSD device your system recognizes as a "hdisk" device you may wonder if it is part of a certain volume group. Issue "lspv" in this case and see all the physical volumes along with the volume groups they belong to.
If you are sure a PV is part of a certain VG and wonder if a certain logical volume is on this PV issue a "lslv -m" to get a map file f the LV.
I am still not sure what you are about (you might consider taking a step back, drink a coffee to come down, then explain what your problem is v-e-r-y s-l-o-w-l-y and concisely), but anyway, 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).
