RHEL: Retrieve and generate a unique SCSI identifier

# Tested on RHEL 5, 6 & 7


# There are many situations were we may need a unique identifier for a SCSI device
# (disk, etc.) to be identified in an unambiguous and persistent way.

# To obtain a SCSI unique identifier, we can use following command:

# RHEL 5
/lib/udev/scsi_id -g -u -s /block/<device>


# RHEL 6
/lib/udev/scsi_id -g -u -d /dev/<device>


# RHEL 7
/usr/lib/udev/scsi_id -g -u -d /dev/<device>
