KNOWN ISSUES FOR CMC
######################################################################
* CMC firmware 1.2 has enhanced the power allocation algorithms to
allow blade servers to receive higher power allocations. If a user
downgrades the CMC to 1.10 or earlier firmware version, servers with
the new higher power allocations could be powered off because the
earlier firmware cannot support the higher chassis power allocations.
If this occurs, you must power the server back on. (230143)
* After a CMC reset, the CMC may require up to one (1) minute after the
login prompt is displayed before RACADM commands will be accepted.
Commands issued prior to that time may receive an error message.(273716)
* RACADM command line tool uses TFTP to transfer image files for all
firmware updates. Only the default port for TFTP (69) is supported
(157754).
* Clearing the CMC Log can take a long time. Please allow up to
one (1) minute for this operation to complete.(152860)
* If the CMC is on a private network without access to the Internet
and you are using Internet Explorer 6 SP 2 or Internet Explorer 7,
you may experience delays of up to 30 seconds when using remote
RACADM commands. (161019)
* Some USB-to-serial adapters have been found to generate a large number of
spurious interrupts when plugged in. If the adapter is connected to
the CMC's serial port when this happens, the CMC can become overloaded
when attempting to service these interrupts and may reboot. This problem is
exacerbated when the serial cable is very long, causing voltage levels to
drop and noise on the serial line to increase. To avoid this issue, Dell
recommends first connecting the USB-to-serial adapter into the USB port,
before connecting to the CMC. Dell also recommends disconnecting
the adapter from the CMC before rebooting or performing other power
management functions on a system that is attached to the CMC. (180373)
* If you setup Active Directory (AD) on the CMC using extended schema and the
built-in Administrator privilege object and then attempt to login to the CMC
User Interface using this AD account, after successful AD login, the user
name and privilege level displayed on the right-hand side of the user interface
just beneath the log out link is displayed as a custom user rather than the
privilege as created on the AD side (example: Administrator, power user).

* Using the RACADM command line utility if you attempt to set the DNS
CMC Name or DNS Domain Name without the proper rules (Rules: start
with an alphabetic character (a-z, A-Z) and follow by an alphanumeric
(a-z, A-Z, 0-9) or a valid symbol (such as -)) then the utility will
display a non-specific error message (ERROR: Unable to perform requested
operation). Please enter a valid name for the above mentioned names.
