    NOTE: For virtual disks, the RAID controller firmware changes the data cache setting based on the state of the battery. If the battery is missing or does not have sufficient charge, the controller flushes the cache and sets the write cache attribute to Write Through for all virtual disks.

  • Page 34: Controller Failure Conditions

    Invalid Storage Array The RAID controller module is supported only in a Dell EMC-supported storage array. After installation in the storage array, the controller performs validation checks. The array status LED is lit with a steady amber color while the RAID controller module completes these initial tests and the controllers are booted successfully.

  • Page 35: Pci Errors

    PCI errors The storage array firmware can detect and only recover from PCI errors when the RAID controller modules are configured for redundancy. If a virtual disk uses cache mirroring, it fails over to its peer RAID controller module, which initiates a flush of the dirty cache.
