Number Severity Description/Recommended actions
357 Warning This event can only result from tests that are run in the manufacturing environment.
Recommended actions:
● Follow the manufacturing process.
358 Critical All PHYs are down for the indicated disk channel. The system is degraded and is not fault
tolerant because all disks are in a single-ported state.
NOTE: ME4 Series systems support only dual-ported disks.
Recommended actions:
● Turn off the power for the controller enclosure, wait a few seconds, and turn it back on.
● If event 359 has been logged for the indicated channel, indicating the condition no longer
exists, no further action is required.
● If the condition persists, this indicates a hardware problem in one of the controller modules
or in the controller enclosure midplane. For help identifying which FRU to replace, see
Troubleshooting and problem solving on page 30.
Warning Some, but not all, PHYs are down for the indicated disk channel.
Recommended actions:
● Monitor the log to see whether the condition persists.
● If event 359 has been logged for the indicated channel, indicating the condition no longer
exists, no further action is required.
● If the condition persists, this indicates a hardware problem in one of the controller modules
or in the controller enclosure midplane. For help identifying which FRU to replace, see
Troubleshooting and problem solving on page 30.
359 Info. All PHYs that were down for the indicated disk channel have recovered and are now up.
Recommended actions:
