CODE EXAMPLE E-7
identifies the
probe-scsi
command output message.
CODE EXAMPLE E-8
identifies the
probe-scsi-all
command output message.:
test-memory
The
test-memory
command tests the main memory if the system
diag-switch?
parameter is set to true. If the system
diag-switch?
parameter is set to false,
the
test-memory
command verifies the memory according to a user-specified number
of megabytes to be examined.
When the
test-memory
command is active, the quantity of memory being tested is
displayed in megabytes and sequentially decrements to zero during the test. If the
diag-switch?
parameter is set to false, the
test-memory
command uses
the
selftest-#megs
parameter in NVRAM to determine the quantity of memory to
test. The default setting for the
selftest-#megs
parameter is 1, thus testing one
megabyte of memory. To change the amount of memory to test, use the
selftest-
#megs
parameter and enter the example command where
XX
is any whole number
that does not exceed the actual size of memory in megabytes.
