Reset Disk
Places the disk in a state from which it can be started. This action might be necessary if the disk was in a STOPPED
state, substate HARDDOWN; a hardware error has occurred; the disk was stopped with an ABORT command; or a
STOP or ABORT fails to put the disk into the STOPPED state, substate DOWN.
Reset Primary Path
Places the primary path in a state from which it can be started.
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.
Start Disk
Starts all paths to this disk drive. When the Start action completes, all paths 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.
Start Volume
Starts all paths for both the primary and mirror drives of this volume.
Stop Backup Path
Terminates operation of the backup path to the disk.When the Stop action finishes, the path is in a Down state. If the
disk drive is currently in use, a dialog box warns you and asks whether or not you want to continue with the action.
Stop Disk
Terminates all paths for this disk drive. When the Stop action finishes, the paths are in a Down state. If the disk drive
is currently in use, a dialog box warns you and asks whether or not you want to continue with the action.
Stop Primary Path
Terminates the primary path to the disk. When the Stop action finishes, the path is in a Down state. If the disk drive
is currently in use, a dialog box warns you and asks whether or not you want to continue with the action.
Stop Volume
Terminates all paths for the primary and mirror drives of this volume.When the Stop action finishes, the paths are in
a Down state.
Switch to Backup Path
Switches processing from the primary to the backup path.
Switch to Primary Path
Switches processing from the backup to the primary path.
Test Verify
Runs the power-on self-test for the disk and tests the internal circuitry of the drive.
Validate Checksum
Scans the user data area of a disk for sector checksum errors. If the action fails, the Action Details dialog box reports
a sector checksum error and suggests that you spare the sector only if you believe there is a drive media problem.
For additional information, use the OSM Event Viewer. Retrieve events using $ZLOG as the source criteria and RAL
as the subsystem criteria, and look for Disk-sector-failure events (event number 7001). In the event detail, a
Sector-failure-count token shows how many sector checksum errors were found, and a Disk-logical-sector token
appears for each error, providing the logical address of that failing sector.
