7.3.3 TILX
The tape inline exerciser (TILX) is a diagnostic tool used to exercise the data
transfer capabilities of selected tape drives connected to an HSJ or HSD30 array
controller. TILX exercises tapes in a way that simulates a high level of user
activity. Thus, TILX can be used to determine the health of the controller and the
tape drives connected to it. You can run TILX from the CLI, from VCS, or from a
virtual (host) terminal.
DILX and TILX may run concurrently with one initiated from a maintenance
terminal and the other from a virtual terminal connection. Digital recommends,
however, that both exercisers not be run while normal I/O operations are in
progress, as system performance will degrade due to the heavy load the exercisers
impose on the controller.
7.3.3.1 Invoking TILX
Note
Before running TILX, be sure that all units you wish to test have been
dismounted from the host.
The following section describes how to invoke TILX from a maintenance terminal
at the CLI> prompt (or HSx> prompt if set), from a VCS, or from a virtual
terminal through a DUP connection.
CAUTION
TILX should be run ONLY using scratch tapes. This test writes to the
tape and destroys any data that exists.
To invoke TILX from a maintenance terminal, enter the following command at
the CLI> prompt:
CLI> RUN TILX
To invoke TILX from the maintenance terminal port using a VCS, enter the
following command at the CLI> prompt:
CLI> VCS CONNECT device_name
where device_name is the controller’s SCS node name.
Consult the VAXcluster Console System User’s Guide for complete details on using
a VCS.
Note
The device_name must be specified for a VCS.
To invoke TILX from a virtual terminal, enter the following command (for
OpenVMS software):
$ SET HOST/DUP/SERVER=MSCP$DUP/TASK=TILX SCS_nodename
where SCS_nodename indicates where TILX will execute.
