3.2 Command Reference
This section provides detailed information on the diagnostic commands and related
commands.
3.2.1 test
The test command runs one pass of diagnostics for the system. To run tests
concurrently and indefinitely, use the sys_exer command. Fatal errors are reported
to the console terminal.
The more el command should be used with the test command to examine test/error
information reported to the console event log.
By default, no write tests are performed on disk and tape drives. Media must be
installed to test the floppy drive and tape drives. A loopback connector is required
for the COM2 (9-pin loopback connector, 12-27351-01) port and parallel port (25-
pin loopback connector) when the -lb argument is used.
