SYSTEM DISABLED—FATAL ERROR
Cause: The MSDL card encountered a fatal error and cannot recover.
The exact reason for the fatal error is shown in the MSDL300 error
message output to the console of TTY when the error occurred.
Action:
Check the MSDL300 message to find out the reason.
Alternatively, display the status of the MSDL, which also indicates
the cause of the problem, with the
STAT MSDL x
command and
check the information to find the cause of the fatal error.
Allow the system to attempt recovery. If this fails, either by reaching
a threshold or detecting self-test failure, place the MSDL in the
manually disabled state with the
DIS MSDL x
command and follow
the steps in “Previously operating MSDL cards” on page 420 .
SYSTEM DISABLED—RECOVERY THRESHOLD
Cause:
The system attempted autorecovery of the MSDL card more than
five times within 30 minutes and each time the card was disabled again.
The system attempts to enable the card again at midnight unless you
intervene.
Action
:
Place the MSDL card in a manually disabled state with the
DIS
MSDL x
command and follow the steps in “Previously operating
MSDL cards” on page 420 .
