5 Command line functionality
Overview
Certain key functions of L&TT are available through the command line, allowing you to sequence
operations using scripts. Command line functionality (CLF) is different from the command line user
interface (CSI version) in that it has no user interface, and therefore no user interaction.
The CLF offers the following possibilities:
•
Simultaneous management of multiple remote devices
Firmware upgrades can be performed on multiple devices located anywhere in the world.
A script is created on the local management machine. L&TT is installed on each remote ◦
server along with a separate script file. The local script simultaneously initiates the remote
scripts to perform the upgrades concurrently. The status of each operation is reported
back to the management machine.
◦ Device health can be monitored on multiple devices using a local script that initiates
remote scripts. The scripts execute a support ticket/report on each device and then parse
the device analysis output to check for any problems.
•
Automated testing
Tests can be run on devices. Each test has no user interaction, but pass/fail output is
reported back for each device. ◦
◦ Device Analysis test can be run on devices. Each Device Analysis ticket is available in a
directory on the remote machine. These tickets can be parsed and the output compared
against a previous successful run.
◦ Unattended repeated testing (regression or stress tests) can be performed to expose any
intermittent issues or memory leaks. The test itself might take only 10 minutes, but by
running it repeatedly in a loop, intermittent problems can be detected. One strategy could
be to run the test until a failure is encountered, at which point the testing is stopped and
a support ticket or report can be generated automatically.
◦ A combination of tests can be run unattended.
Running multiple instances of L&TT
You can run multiple instances of L&TT at the same time to test different elements of a device. For
example,
•
One instance of L&TT can run a system performance test while another can run a device
performance test on a selected device.
•
In an autoloader, one instance of L&TT can run a device analysis test on the media changer
while another runs a Read-Write test on the tape drive.
•
In a library with 24 tape drives, 24 instances of L&TT can test each of the tape drives in
parallel.
To run multiple instances of L&TT, use the optional instname option to specify a name for the
second and subsequent instances of L&TT. L&TT uses the instname to create a folder for the L&TT
runtime files. For more information, see the definition of the instname option in the command
line functions.
L&TT displays a warning dialog when you start the second and subsequent instances of L&TT. If
you are running multiple instances of L&TT on purpose, continue the new instance.
