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 disabled mode, if a CMC with firmware version 1.30 or 1.31 is inserted into
the chassis, then update the CMC firmware to 1.36 and run the options to disable the PERC again.
The shared hard disk drives (HDDs) and 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 the support site.
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 on.
Some advanced features require CMC enterprise license. For more information about the CMC licenses,
see the
Chassis Management Controller for PowerEdge VRTX User's Guide available at the support site.
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. This may
also cause the CMC and the TTY log to be out of sync for a short period of time.
In fault-tolerant (Redundant) mode, the controller associated with virtual disks or physical disk drives is
the active controller.
When saving Server Profile under "Server Overview > Setup > Profiles", the list of characters that are not
supported for the Profile Name include the characters hash(#), comma(,), and question mark(?).
You may see an impact in the performance of the Graphical User Interface with this release of CMC. The
performance impact varies by configuration, GUI page, and system load.
