Configuring a Single-Disk Unit
Follow these steps to use a single disk drive as a single-disk unit in your subsystem:
1. Add the disk drive by following the steps in “Adding Disk Drives,” page 6–3.
Optionally, you can append Device switch values. If you do not specify switch
values, the default values are applied.
2. Initialize the disk drive using the following command:
INITIALIZE DISk nnn switch
3. Present the disk drive to the host by giving it a unit number the host can
recognize. Optionally, you can append Unit switch values. If you do not specify
switch values, the default values are applied. Use the following command:
ADD UNIT unit-number DISK nnn switch_value
NOTE: If you make a disk transportable, you cannot specify WRITEBACK_CACHE
for that disk.
a. For OpenVMS hosts, set the unit number to a decimal value, ranging from
1–9999. Usually, this number is the same as the unit number set in step 3.
SET unit-number identifier = nnnn
4. Verify the configuration using the following command:
SHOW DEVICES
Example
The following example shows the commands you would use to configure DISK10000
as a single-disk unit.
ADD DISK DISK10000 1 0 0
ADD UNIT D101 disk10000
SHOW DEVICES
See Chapter 7, “CLI Commands” for further information on these switches and
values.
