3.1.4.3 The SELECT Command
The SELECT command is used to specify a device for maintenance before you
perform a format, qualify, or exercise operation.
Use the SHOW command to determine if the device is AVAILABLE to the HSD05
array controller. Devices that are listed as being OFFLINE or ONLINE to the
HSD05 array controller cannot be selected.
When a device is selected, its operational status becomes MAINT and the device
is not available to the OpenVMS operating system.
Command Syntax
The following is the syntax of the SELECT command:
SELECT device_name
The symbol
device_name
refers to a valid MSCP/TMSCP device label for either
a direct access or sequential access device. Direct access devices, such as disk
drives, are specified with the ‘‘DIA’’ or ‘‘DUA’’ prefix to the device label, for
example, ‘‘DIA100’’. Sequential access devices, such as tape drives, are specified
with the ‘‘MUA’’ prefix, for example, ‘‘MUA120’’.
Example 3–3 is an example of the SELECT operation display.
