Need WWN

How do I identify the WWN of associated SAN through a logical volume that is mounted on a RHEL 6 system

I don't have Linux systems with physical-connected SAN anymore, but just to give you a direction - lsblk shows, which logical volume lays on which disk. Then you can use e.g. lsscsi to find the WWNs.

lvs -o +devices /dev/mapper/your_lvm

this will show us the associated disk in this logical volume.

Then run the scsi_id command as follows.

scsi_id -g /dev/sda
