SRM Console Diagnostics 4-55
Use the show_status command to display the progress of diagnostic tests.
The diagnostics started by the sys_exer command automatically reallocate
memory resources, because these tests require additional resources. Use the
init command to reconfigure memory before booting an operating system.
Because the sys_exer tests are run concurrently and indefinitely (until you stop
them with the init command), they are useful in flushing out intermittent
hardware problems.
When using the sys_exer command after shutting down an operating system,
you must initialize the system to a quiescent state. Enter the following
command at the SRM console:
P00>>> init
.
.
.
P00>>> sys_exer
By default, no write tests are performed on disk and tape drives. Media must be
installed to test the floppy drive and tape drives. When the -lb argument is
used, a loopback connector is required for the COM2 port (9-pin loopback
connector, 12-27351-01) and parallel port (25-pin loopback connector).
Syntax
sys_exer [-lb] [-t]
Arguments
[-lb]
The loopback option runs console loopback tests for the COM2 serial
port and the parallel port during the test sequence.
[-t] Number of seconds to run. The default is run until terminated by a
kill or kill_diags command.
