Switching the controller mode

On PERC 9.1 and later controllers, you can change the personality of the controller by switching the mode from RAID to HBA. The controller operates similar to a HBA controller where the drivers are passed through the operating system. The controller mode change is a staged operation and does not occur in real time. Before you change the mode of the controller from RAID to HBA, ensure that:
  • The RAID controller supports the controller mode change. The option to change the controller mode is not available on controllers where the RAID personality requires a license.
  • All virtual disks must be deleted or removed.
  • Hot spares must be deleted or removed.
  • Foreign configurations must be deleted or cleared.
  • All physical disks that are in a failed state, must be removed.
  • Any local security key associated with SEDs must be deleted.
  • The controller must not have preserved cache.
  • You have server control privileges to switch the controller mode.
  • NOTE: Ensure that you back up the foreign configuration, security key, virtual disks, and hot spares before you switch the mode as the data is deleted.
  • NOTE: Ensure that a CMC license is available for PERC FD33xS and FD33xD storage sleds before you change the controller mode. For more information on CMC license for the storage sleds, see the Dell Chassis Management Controller Version 1.2 for PowerEdge FX2/FX2s User's Guide available at dell.com/support/manuals.
