In order to increase the flexibility and utility of the db Disk.name field it is proposed that it be re-deployed to hold by-id device names as opposed to the current ‘sd’ type names. This in combination with the Disk.role field is intended to aid in supporting additional storage options such as LUKS full disk encryption.

Ie change:
/dev/sdX derived from a db entry of sdX
to:
/dev/disk/by-id/wwid-for-device derived from a db entry of wwid-for-device.

A World Wide Identifier (WWID) is a persistent and system independent identifier required of all SCSI standards compliant devices.
