presenting luns from linux host to another

we have an old linux host that it lost it's boot disk and won't boot up anymore.  What we did is we moved those luns to another linux host. There are 9 luns all together.  from the other linux host, we did a rescan:

1. echo "- - -" > /sys/class/scsi_host/host3/scan (bus scan) (starting with host0)

2.pvscan

pvscan

  PV /dev/emcpoweri1   VG VolGroup01   lvm2 [50.00 GB / 10.00 GB free]

  PV /dev/emcpowern    VG vg_data      lvm2 [110.00 GB / 0    free]   ==>  lun from old host

  PV /dev/emcpowert    VG vg_data      lvm2 [120.00 GB / 0    free] ==> lun from old host

  PV /dev/emcpowerm    VG vg_data      lvm2 [650.00 GB / 0    free ==> lun from old host]

  PV /dev/sda5         VG VolGroup00   lvm2 [273.56 GB / 128.09 GB free]

  PV /dev/sda2         VG VolGroup00   lvm2 [5.00 GB / 5.00 GB free]

  Total: 6 [1.18 TB] / in use: 6 [1.18 TB] / in no VG: 0 [0   ]

NOTE: only 3 LUNS/Volumes are showing up. We enabled the 'vg_data' volume group and was able to mount those volumes.

so we are missing 6 other LUNS and those aren't showing up as part of a Volume Group.

this are the 9 luns from the Clariion array:

  HLU Number     ALU Number

  ----------     ----------

    0               82

    1               120

    2               121

    3               160

    4               83

    5               150

    6               81

    7               84

    8               85

POWERPATH shows all luns.

pvdisplay -C --separator '  |  ' -o pv_name,vg_name

  PV  |  VG

  /dev/emcpoweri1  |  VolGroup01

  /dev/emcpowerm  |  vg_data

  /dev/emcpowern  |  vg_data

  /dev/emcpowert  |  vg_data

  /dev/sda2  |  VolGroup00

  /dev/sda5  |  VolGroup00

WE do not know what luns belongs to what VG since the original host is already gone/won't boot.

Is there any idea on what to look at to figure out the VGs of the other LUNs that are NOT showing on PVSCAN ?

Thanks. We need to recover those data.
