Controller Failure Conditions

Certain events can cause a RAID controller module to fail and/or shut down. Unrecoverable ECC
memory or PCI errors, or critical physical conditions can cause lockdown. If your RAID storage array is
configured for redundant access and cache mirroring, the surviving controller can normally recover
without data loss or shutdown.

Critical Conditions

The storage array generates a critical event if the RAID controller module detects a critical condition that
could cause immediate failure of the array 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 midplane temperature sensors in the critical range
Midplane/power supply module failure
Two or more temperature sensors are unreadable
Failure to detect or unable to communicate with peer port
NOTE: If both RAID controller modules fail simultaneously, the enclosure cannot issue critical or
noncritical event alarms for any enclosure component.
