When using the test command after shutting down an operating system, you must
initialize the system to a quiescent state. Enter the following command at the SRM
console:
>>> init
.
.
.
>>> test
The tests are run in the following order:
1. Memory tests (one pass).
2. Read-only tests: DK* disks, DR* disks, DU* disks, MK* tapes, DV* floppy.
3. Console loopback tests if -lb argument is specified: COM2 serial port and
parallel port.
4. VGA/TGA console tests. These tests are run only if the console environment
variable is set to serial. The VGA/TGA console test displays rows of the word
“digital.”
5. Network external loopback tests for E*A0. This test requires that the Ethernet
port be terminated or connected to a live network or the test will fail.
NOTE: Because traffic on live networks is unpredictable, loopback timeouts are
considered soft errors.
Syntax
test [-lb]
Argument:
[-lb] The loopback option includes console loopback tests for the COM2
serial port and the parallel port during the test sequence.
