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.
