Reset Volume
Places the volume in a state from which it can be started.
Responsive Test
Verifies that the disk drive is installed and responding.
Start Backup Path
Starts the backup path to this disk drive. When the Start action completes, the backup path is in the
Started state.
This action fails if both paths to this disk are down and the mirrored disk is Up. For more
information, see Start Disk.
Start Disk
Use this action to start all paths to the disk drive only when:
The disk paths are in a Down state. (Hard Down states require a reset action, either Reset Disk,
Reset Primary Path, or Reset Backup Path as appropriate.)
●
Its mirrored disk is not currently Up. The Start Disk action is designed to fail if the mirrored
disk is already in an Up state because the mirror and primary disk volumes can have different
data and require a revive operation. To revive and bring up the disks properly, use the OSM
Start Volume action or SCF START DISK command.
●
When the action completes successfully, all paths to the disk are in the Started state.
Start Primary Path
Starts the primary path to this disk drive. When the Start action completes, the primary path is in the
Started state.
This action fails if both paths to this disk are down and the mirrored disk is Up. For more
information, see Start Disk.
Start Volume
Starts all paths for both the primary and mirror drives of this volume unless they are in a Hard Down
state. Disk paths in a Hard Down state require a reset action first (either Reset Disk, Reset Primary
Path, or Reset Backup Path as appropriate).
