3.1.4.9 The TAPETEST Command
This command performs a tape exercise on the selected tape device. This test
requires enough tape to accommodate 10 megabytes of 1-kilobyte blocks. The
device to be exercised must first be selected with the SELECT command.
Command Syntax
The following is the syntax of the TAPETEST command:
TAPETEST device_name
The symbol
device_name
refers to a valid TMSCP device label for a direct access
or sequential access device. Tape drives are specified with the ‘‘MUA’’ prefix to
the device label.
Command Description
The TAPETEST exercise consists of writing, rewinding, and reading each section
of tape, up to but not including a filemark. Block sizes start at 32 kilobytes and
are halved on each successive write/rewind/read pass. The test is restarted when
the block size reaches 1 kilobyte.
You are prompted to confirm the TAPETEST operation on the selected drive.
Answering ‘‘N’’ or ‘‘NO’’ aborts the operation with no change to the data on the
device. Answering ‘‘Y’’ or ‘‘YES’’ to this prompt starts the TAPETEST operation
on the device.
The TAPETEST operation replaces media errors when encountered. If other
types of errors occur, the test is stopped and the error condition is displayed in
the Maint Status field of the display.
Terminating the Test
TAPETEST runs until it is terminated with the ABORT command or until the
HSD05 array controller is powered off.
Example 3–9 shows a TAPETEST run.
