What disk identifier am I look at here?

[framewrangler]

This test pool has had a disk removed. What is that identifier being used in the "name" column? It's not my WWN/LUN ID, UUID or GPTID. If possible I want to document said identifier for all of my current and future disks to ease management and replacements.

Thanks

Code:

[root@freenas] /tmp# zpool status
  pool: aaa
state: DEGRADED
status: One or more devices has been removed by the administrator.
        Sufficient replicas exist for the pool to continue functioning in a
        degraded state.
action: Online the device using 'zpool online' or replace the device with
        'zpool replace'.
  scan: none requested
config:
 
        NAME                                            STATE    READ WRITE CKSUM

It is the ZFS GUID. Run "zdb" to get GUIDs of all devices.

Much appreciated. I'll add that to my spreadsheet and related docs.
