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 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 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 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, and
could also make 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.
 Microsoft Windows Server 2012, Windows Server 2008 R2, Windows 7 do not support TLS 1.2 and
