How to Identify the NAA ID for a Specific Disk in a RHEL VM

Solution Verified - Updated -

Issue

  • You need to identify the Network Address Authority (NAA) ID of specific block devices (e.g., /dev/sde, /dev/sdf) from within your RHEL virtual machine.
  • Standard /dev/sdX device names are not persistent and can change upon reboot or disk configuration modifications, making consistent disk identification challenging.

Environment

  • Red Hat Enterprise Linux (RHEL) (Versions 6, 7, 8, 9)
  • Virtual disks presented to the RHEL VM.
