Disk Movement and Device ID Overview

Solaris Volume Manager uses device IDs, which are associated with a specific disk, to track all disks that are used in a Solaris Volume Manager configuration. When disks are moved to a different controller or when the SCSI target numbers change, Solaris Volume Manager usually correctly identifies the movement and updates all related Solaris Volume Manager records accordingly. No system administrator intervention is required. In isolated cases, Solaris Volume Manager cannot completely update the records and reports an error on boot.
