Dell recommends that you upgrade the firmware for the internal H710 RAID controller.  It will require 5-10 minutes to install the update and require a 10 minute reboot.

Download the PERC RAID Controller firmware for your specific system.  Look for the Red Hat Linux Update Package (.BIN).  For Example:

H710: http://www.dell.com/support/home/us/en/04/drivers/driversdetails?driverid=kkr9j

H730: https://www.dell.com/support/home/us/en/04/drivers/driversdetails?driverid=f675y

Download the Red Hat Linux Update Package (.BIN) file to /home on the sensor.

To update the firmware do the following:

• Login as root.
• Shutdown Security Analytics using:  scotus stop
• To install the firmware:
  • chmod 755 /home/SAS-RAID_Firmware_XXXXX_LN_VERSION_AXX.BIN
• Update the firmware:
  • /home/SAS-RAID_Firmware_XXXXX_LN_VERSION_AXX.BIN

This will take a few minutes, There will be verification that the firmware is the correct firmware for the hardware and lots of license details.  Once it is done, it will reboot the system.  

SA should come online after the reboot.
