Solution:

1. check the Device size in multipath output.

[root@ORADB36 ~]# multipath -ll
STOR05-IFS25-LOGS01 (36486fd25560a93e0ed24d9ae89bb039b) dm-6 MSFT    ,STORSIMPLE 8100
size=2.4T features='0' hwhandler='0' wp=rw
`-+- policy='service-time 0' prio=1 status=active
  `- 14:0:0:15 sdg 8:96  active ready running

2. VG activation is giving error.

[root@ORADB36 ~]# vgchange -ay ORALOGS
  WARNING: Device /dev/mapper/STOR05-IFS25-LOGS01 has size of 5242880000 sectors which is smaller than corresponding PV size of 5452593152 sectors. Was device resized?
  One or more devices used as PVs in VG ORALOGS have changed sizes.
  device-mapper: resume ioctl on (251:8) failed: Invalid argument
  Unable to resume ORALOGS-archlogs (251:8)
  1 logical volume(s) in volume group "ORALOGS" now active
[root@ORADB36 ~]#

3. Now Restore the VG.

[root@ORADB36 ~]# vgcfgrestore -f /etc/lvm/archive/ORALOGS_00002-820455485.vg ORALOGS
  Restored volume group ORALOGS
[root@ORADB36 ~]#

4. Check that restores VG size.

[root@ORADB36 ~]# pvs
  PV                              VG         Fmt  Attr PSize   PFree
  /dev/mapper/ORADB36_DATA1       ORADB36U01 lvm2 a--    7.00t 512.00g

[root@ORADB36 ~]#

[root@ORADB36 ~]# vgs
  VG         #PV #LV #SN Attr   VSize   VFree
  ORADB36U01   1   1   0 wz--n-   7.00t 512.00g

  ol           1   4   0 wz--n- 555.33g      0

 5. Now proceed with Normal pv and lv extend steps.
