using autorecovery. If a diagnostic program (overlay) is active, the
downloading of the MSDL base code occurs later.
Action
:
Wait to see if the system will enable the card immediately. If the
MSDL is enabled, no further action is necessary.
If the MSDL base code download fails five times, autorecovery
stops. The following appears in response to the
STAT MSDL x
command;
Error messages will usually indicate the problem in this case. See
“Maintaining the MSDL” on
SYSTEM DISABLED—SELF-TESTS FAILED
Cause:
The card did not pass self-tests. These tests repeat five times. If
unsuccessful, autorecovery stops until midnight unless you take action.
Action
:
Allow the system to repeat the self-tests.
If self-tests fail repeatedly, disable the card using the
DIS MSDL x
command and replace the card.
SYSTEM DISABLED—SRAM TESTS FAILED
Cause:
After self-tests passed, the system attempted to perform read/
write tests to the shared RAM on the MSDL and detected a fault. The
shared RAM test will be repeated five times, and, if unsuccessful,
autorecovery will not resume until midnight unless you take action.
Action:
Allow the system to repeat the self-tests.
If self-tests fail repeatedly, disable the card using the
DIS MSDL x
command and replace the card.
