DILX
Checking for Disk Drive Problems
Use DILX to check the data-transfer capability of disk drives. DILX generates intense
read/write loads to the disk drive while monitoring drive performance and status. Run
DILX on as many disk drives as desired, but since this utility creates substantial I/O loads
on the controller, Compaq recommends stopping host-based I/O during the test.
IMPORTANT: DILX cannot be run on remote copy sets (ACS V8.5P only).
Finding a Disk Drive in the Subsystem
Use the following steps to find a disk drive or device in the subsystem:
1. Connect a PC or a terminal to the controller maintenance port.
2. Show the devices that are configured on the controller with the following command:
SHOW DEVICES
3. Find the device in the enclosure with the following command:
LOCATE device-name
This command causes the device LED to blink continuously.
4. Enter the following command to turn off the LED:
LOCATE CANCEL
Testing the Read Capability of a Disk Drive
Use the following steps to test the read capability of a disk drive:
1. From a host console, dismount the logical unit that contains the disk drive being tested.
2. Connect a terminal to the controller maintenance port that accesses the disk drive
being tested.
3. Run DILX with the following command:
RUN DILX
