Release Notes

Important Notes

• It is recommended not to downgrade CMC or Mainboard firmware below the supported versions mentioned in this Release notes,

since previous versions of CMC and Mainboard do not support SPERC disable option.

• When the second SPERC is in the disabled mode, if a CMC with firmware version 1.30 or 1.31 is inserted into the chassis, then update

the CMC firmware to 1.35 and run the options to disable the PERC again.

• The shared hard disk drives (HDDs) and the PCIe cards are managed by the CMC and are not visible to the operating system in the

server modules, until the HDDs and PCIe cards are mapped by using the CMC web interface. For instructions about mapping PCIe

cards and managing the Storage subsystem, see the Chassis Management Controller for PowerEdge VRTX User's Guide available at

dell.com/cmcmanuals.

• All the server modules must be turned off before updating the firmware for chassis infrastructure and SPERC. CMC firmware can be

updated while the servers are turned on.

• Some advanced features require CMC enterprise license. For more information about the CMC licenses, see the Chassis Management

Controller for PowerEdge VRTX Version User's Guide available at dell.com/cmcmanuals.

• Before updating the Storage component using the web interface, make sure that the browser’s Cookies are enabled.

• PERC Storage rebuild may take more time when more number of I/O requests are processed, and could also make CMC and the TTY

log to be out of sync for a short period.
