Critical Conditions

The storage array will generate a critical event if the RAID controller module detects a critical condition that could cause immediate failure of the enclosure and/or loss of data. The storage array is in a critical condition if one of the following occurs:

More than one fan has failed

Any backplane temperature sensors in the critical range

Backplane/power supply failure

Two or more temperature sensors are unreadable

Failure to detect or unable to communicate with peer in duplex configuration

NOTE: If both RAID controller modules fail simultaneously, the enclosure cannot issue critical or noncritical event alarms for any enclosure component.

When the enclosure is under critical condition, its enclosure status LED blinks amber.

Noncritical Conditions

A noncritical condition is an event or status that will not cause immediate failure, but must be corrected to ensure continued reliability of the storage array. Examples of noncritical events include the following:

One power supply has failed

One cooling fan has failed

One RAID controller module in a redundant configuration has failed

A battery has failed or has been removed

A physical disk in a redundant virtual disk has failed

When the enclosure is under non-critical condition, its enclosure status LED shows steady amber.
