Hi All,

I have a RedHat4 server connected to a SAN 3510 Array.  On the
host server, there are two volume groups set up--root_vg and
san_vg.  I'm assuming that root_vg resides on the internal disks
and san_vg on the SAN.  But, how can I check to make sure this is
the case?


This is what I get when I run pvscan.  pvs is similar.

# pvscan
  PV /dev/sda4   VG main_huge_vg   lvm2 [529.00 GiB / 0    free]
  PV /dev/sdb2   VG main_huge_vg   lvm2 [594.25 GiB / 0    free]
  PV /dev/sdc1   VG main_huge_vg   lvm2 [931.50 GiB / 0    free]
  PV /dev/sdd1   VG main_huge_vg   lvm2 [698.62 GiB / 0    free]
  PV /dev/sde1   VG main_huge_vg   lvm2 [931.50 GiB / 0    free]
  Total: 5 [3.60 TiB] / in use: 5 [3.60 TiB] / in no VG: 0 [0   ]
