From the above outputs, looks like dm-7 is not for any of your file systems.

mpathb (3600508b4000d3f600000600006430000) dm-7 HP,HSV450
[size=40G][features=1 queue_if_no_path][hwhandler=0]

mpatha (3600508b4000d3f600000600006d30000) dm-6 HP,HSV450
[size=11G][features=1 queue_if_no_path][hwhandler=0]

dm-6 is used by
Code:
/dev/mapper/vg02-lv00
                      9.9G  1.1G  8.9G  11% /oracle

pvs
Code:
PV                VG   Fmt  Attr PSize   PFree
/dev/dm-6     vg02 lvm2 a-    11.00G 1020.00M


vgs
Code:
VG   #PV #LV #SN Attr   VSize   VFree
vg02   2   1   0 wz--n-  21.99G 11.99G

lvs
Code:
 LV          VG   Attr   LSize   Origin Snap%  Move Log Copy%
 lv00        vg02 -wi-ao  10.00G

Note that, you VG vg02 has 2 disks (dm-6 and dm-8), dm-8 is not used at all and not added to any volume but these 2 are from different arrays.
