[linux-lvm] determining boot disk name(/dev/sd...) on RHEL LVM

[siva krishna]

Hi all,

is there a way to determine the device name (eg: /dev/sda, /dev/sdb)
on lvm partitioned disks,  when the os is booted from the lvm partitioned
disk
and there are also multiple disks connected which are having lvm partions
with same volume group names as the primary disk.

i tried doing vgdisplay
 and then correlating it's output with cat /etc/fstab, cat /etc/cmdline

but there are multiple volume groups having the same name so can't find
from which volume the RHEL is booting

Thanks
siva
