<div> </div>
<div>is there a way to determine the device name (eg: /dev/sda, /dev/sdb)</div>
<div>on lvm partitioned disks, when the os is booted from the lvm partitioned disk</div>
<div>and there are also multiple disks connected which are having lvm partions with same volume group names as the primary disk.</div>
<div> </div>
<div>i tried doing vgdisplay</div>
<div> and then correlating it's output with cat /etc/fstab, cat /etc/cmdline</div>
<div> </div>
<div>but there are multiple volume groups having the same name so can't find from which volume the RHEL is booting</div>
<div> </div>
<div>Thanks</div>
