    You will need to:

    1. vxprint -d (see current disk sizes)
    2. expand the 2 Luns on EMC storage
    3. vxdctl enable 
    4. vxdisk -g oradg01 resize emcpowera (grow disk)
    5. vxdisk -g oradg02 resize emcpowerb (grow disk)
    6. vxprint -d (check disk sizes have increased)
    7. check space available to grow datavol01:
      vxassist -g oradg01 maxgrow datavol01
    8. check space available to grow datavol02:
      vxassist -g oradg02 maxgrow datavol02
    9. Grow filesystem (size you can grow will depend on output from 7):
      vxresize -g oradg01 datavol01 +354
    10. Grow filesystem (size you can grow will depend on output from 8):
      vxresize -g oradg02 datavol02 +352

    Note on your systems you have 2 disks each containing 1 filesystem, but you could have 2 filesystems on one disk - this is why growing disks and filesystems are separate steps
