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:

● 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 31.
Warning Some, but not all, PHYs are down for the indicated disk channel.
