Troubleshooting RAID Controller Modules
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.
