The test Command
The
test
command runs firmware diagnostics for the entire core system. The tests are
run sequentially, and the status of each subsystem test displays on the console terminal as
the tests progress. If a particular device is not available to test, a message displays.
The test script is made up of several exercisers that can test subsystems. The
test
command runs these exercisers sequentially and the status of each subsystem test displays
on the console terminal as the tests progress. If a device is not available to test, a message
displays. The test script does no destructive testing, that is, it does not write to disk drives.
To run a complete diagnostic test using the
test
command, the system configuration
must include:
•
Serial loopback connected to the COM2 port
•
Parallel loopback (12-27351-01) connected to the parallel port
•
Connection to a network or a terminator connected to the Ethernet port
•
A diskette with files installed
•
A trial CD-ROM with files installed
The test script tests devices in the following order:
1.
Console loopback tests if
1b
argument is specified: COM2 serial port and parallel port
2.
Network external loopback tests for EW: this test is run if a Digital Ethernet controller
(EW) is present. The test requires that the Ethernet port be terminated or connected to
a live network; otherwise, the test will fail.
3.
Memory tests
4.
Read-only tests: DK, DR, and DU disks,; MK tapes and DV diskettes
5.
VGA console tests: these tests are run only if the console environment variable is set
to "serial." The VGA console test displays rows of the letter "H."
__________________________ Note _____________________________
By default, no write tests are performed on disk and tape drives. Media must be
installed to test the diskette drive and tape drives.
