Starting and Testing the Tape Drives (NonStop
Himalaya S-Series Servers)
You have the option of specifying parameters that denote the length of tape to write,
the length of the records to be written to tape, the mode in which the tape should be
exercised, and so on. The following is an example of an EXERCISE command that
tests a streaming tape device in stream mode for two loops using a record length of 24:
TAPE> EXERCISE $TAPE0, LOOP 2, RECLENGTH 24, &
TAPE> &ENDSTATE UNLOAD, TAPEMODE STREAM
For details on the TMDS TAPE subsystem and TMDS TAPE commands, refer to
Section 5, Using TMDS or the TSM Package, or the TMDS Reference Manual.
Starting and Testing the Tape Drives (NonStop
Himalaya S-Series Servers)
This subsection describes the SCF commands you can use to start and test your tape
devices after the modular tape subsystem is installed.
Starting a Tape Device
You use the SCF START TAPE command to start a tape device after the modular tape
subsystem has been installed. The START command makes a stopped tape drive
accessible to user processes. When the START command finishes successfully, the
tape drive is in the STARTED state.
The following is an example of an SCF START TAPE command:
->START $TAPE0
For more on the START command, see Starting a Cartridge Tape Drive on page 4-37
and refer to the SCF Reference Manual for the Storage Subsystem.
Testing a Tape Device
You can use the TSM package, BACKUP and RESTORE, or SCF to test tape
subsystems.
1. The TSM Service Application supports the following tests for tape subsystems:
TSM Action Information Source
Tape Responsive Test From the TSM Service Application, verifies that a tape drive
is installed and responding.
Test Extended From the TSM Service Application, performs a loop write-to-
read test.
Test Verify From the TSM Service Application, runs a POST on the
tape drive, plus additional tests to isolate problems (tape
drive must be down state).
