Dell Serial Attached SCSI 5iR Integrated and Adapter - Manual (Page 43)

Updating the Firmware 41
Updating the Firmware
Firmware updates to the Dell™ Serial-Attached SCSI (SAS) 5/iR controller is achieved by flashing
the firmware. The firmware can be flashed while the controller is in use. The system must be
restarted for the changes to the firmware to take effect. If there is a failure while flashing the
firmware (such as a power outage) the controller reverts back to the earlier version of the firmware.
NOTE: If you flash the firmware while using the controller, you may notice temporary degradation in the
controller's performance.
Firmware Update Utility
Firmware update utility can be run from a variety of operating systems. Firmware flash is automated
and no user intervention is required. You can obtain firmware flash utility from the
Dell™ PowerEdge™ Service and Diagnostic Utilities CD.
Running the firmware update utility from the operating system is not supported on Dell Precision
workstations. You have to perform a manual update. In the event of new firmware release, check the
Dell support site at support.dell.com for the latest firmware updates and the firmware
update procedure.
NOTICE: Do not attempt to downgrade the firmware from the 10.x version (or higher) to the 6.x version. This
puts the controller in a non-functional state.
