APC 15000 RAID manual Displaying System Uptime, Saving a Comment to the Log

To display the number of LUN array parity errors detected by the system, use the FAULTS ARRAYPARITY command. The system saves the counts for each tier of all the LUNs. To clear the count of LUN array parity errors in the system, use the FAULTS ARRAYPARITYCLEAR command.

FAULTS BUSPARITY displays the number of bus parity and data path errors detected by the system.

FAULTS BUSPARITYCLEAR clears the count of errors.

You may set a parameter (ECCSHUTDOWN) that allows the system to automatically shutdown if it encounters an unrecoverable error. Use the FAULTS ECCSHUTDOWN=on command to enable automatic shutdown for unrecoverable ECC errors. This is the default setting. To disable and allow the system to continue to run in spite of unrecoverable ECC errors, use the FAULTS ECCSHUTDOWN=off.

The EXCEPTIONSHUTDOWN command parameter allows the system to automatically shutdown if it encounters a task exception.

FAULTS EXCEPTIONSHUTDOWN=ON enables automatic shutdown for task exceptions. This is the default setting.

The FAULTS EXCEPTIONSHUTDOWN=OFF disables automatic shutdown and allows the system to continue to run in spite of task exceptions.
