The output from this example indicates that $DATA00:
• Is a mirrored volume (primary and mirror paths)
• Has a mirror disk that is being revived (SubState REVIVE)

Monitoring the State of Disk Drives
Each disk drive can have two paths, the primary and the backup. (Each M8xxx disk drive is forced
to have two paths.) The two path states are represented separately.
Table 27 Primary and Backup Path States for Disk Drives
DescriptionPath State
