No, Paging space is used by the system for all tasks, not tasks associated with a specific disk.
In olden times when memory was very expensive Paging Space was used as an extra portion of memory for processes. Now a days you want to avoid using paging space of at all possible as it slows the application down unnecessarily.
If you have a lot of reads and writes to the one VG you may wish to compose the VG of multiple disks or LUNs and stripe the data across those to get more disk heads accessing your data.

vgimportclone
VGIMPORTCLONE(8) System Manager's Manual VGIMPORTCLONE(8)
NAME
vgimportclone - import and rename duplicated volume group (e.g. a hardware snapshot)
SYNOPSIS
vgimportclone [-n|--basevgname VolumeGroupName] [-i|--import] PhysicalVolume [PhysicalVolume...]
DESCRIPTION
vgimportclone is used to import a duplicated VG (e.g. hardware snapshot). Duplicate VG(s) and PV(s) are not able to be used until they are
made to coexist with the origin VG(s) and PV(s). vgimportclone renames the VG associated with the specified PV(s) and changes the associ-
ated VG and PV UUIDs.
OPTIONS
See lvm for common options.
-n|--basevgname VolumeGroupName
By default the snapshot VG will be renamed to the original name plus a numeric suffix to avoid duplicate naming (e.g. 'test_vg'
would be renamed to 'test_vg1'). This option will override the base VG name that is used for all VG renames. If a VG already
exists with the specified name a numeric suffix will be added (like the previous example) to make it unique.
-i|--import
Import exported Volume Groups. Otherwise VGs that have been exported will not be changed (nor will their associated PVs).
ENVIRONMENT VARIABLES
LVM_BINARY
The LVM2 binary to use. Defaults to "lvm".
EXAMPLES
The origin VG vg00 has origin PVs /dev/sda and /dev/sdb and the respective snapshot PVs are /dev/sdc and /dev/sdd. To rename the VG asso-
ciated with /dev/sdc and /dev/sdd from vg00 to vg00_snap (and to change associated VG and PV UUIDs) do:
vgimportclone --basevgname vg00_snap /dev/sdc /dev/sdd
