CMM secure TCPCMDMODE gets turned off - IBM BladeCenter Open Fabric Manager



Source

RETAIN tip: H207762

Symptom

For the IBM Flex System Chassis Management Module, Option part number 68Y7029, (CMM) running firmware 10I:

  • 'stcme'/secure TCPCMDMODE was turned off and settings are not saved on a user's system.

If secure TCPCMDMODE is off, then the IBM BladeCenter Open Fabric Manager (BOFM) server will not be able to connect to the CMM. A CMM configured to use BOFM cannot connect to it and the user will be notified of the connection failure on the BOFM GUI.

Affected configurations

The system is configured with at least one of the following:

  • IBM BladeCenter Open Fabric Manager 1.0, any version

The system is configured with one or more of the following IBM Options:

  • Flex System Chassis Management Module, Option part number 68Y7029, any replacement part number (CRU)

This tip is not system specific.

The I10 firmware for the CMM is affected.

Note: This does not imply that the network operating system will work under all combinations of hardware and software.

Please see the compatibility page for more information: http://www.ibm.com/systems/info/x86servers/serverproven/compat/us/

Solution

This behavior will be corrected in a future release of CMM firmware.

The target date for this release is scheduled for second quarter 2013.

The file is or will be available by selecting the appropriate Product Group, type of System, Product name, Product machine type, and Operating system on IBM Support's Fix Central web page, at the following URL:

Workaround

From the CMM's Command Line Interface (CLI):

  tcpcmdmode -T MM[x] -status 0
tcpcmdmode -T MM[x] -t 0
tcpcmdmode -T MM[x] -sstatus 5
ports -stcme on -T MM[x]

where: x is the affected CMM's bay number

The workaround will fix both the connection and settings issues.

Additional information

After issuing these commands, secure TCPCMDMODE is enabled and BOFM can connect with the CMM.
