Changing node boot sequence via CMM causes failure

Troubleshooting

Problem

Node boot sequence change via the Command Line Interface (CLI) or Web User Interface (UI) fails in Lenovo Chassis Management Module II (CMM2) firmware up to and including Build ID: 1AON02C. The symptom can be observed by performing the following: 1.system> env -T blade[2] OK 2. system:blade[2]> bootseq Boot Order List --------------- 12 (CD/DVD Rom) 8 (Hard Disk 0) 6 (PXE Network) 163 (RHELTEST) Note: The max of 255 devices can be selected for boot sequence.

Symptom

Node boot sequence change via the Command Line Interface (CLI) or Web User Interface (UI) fails in Lenovo Chassis Management Module II (CMM2) firmware up to and including Build ID: 1AON02C.

The symptom can be observed by performing the following:

	1.system> env -T blade[2] OK 2. system:blade[2]> bootseq Boot Order List --------------- 12 (CD/DVD Rom) 8 (Hard Disk 0) 6 (PXE Network) 163 (RHELTEST) Note: The max of 255 devices can be selected for boot sequence. Available Boot Device List -------------------------- . .. ... 3.system:blade[2]> bootseq -seq 163\|12\|8\|6 OK 4. system:blade[2]> bootseq Getting boot sequence of blade failed system:blade[2]> WEB UI also fails with the following error message: -> Unable to retrieve data for this node.

Affected Configurations

The system may be any of the following Lenovo servers:

Lenovo Flex System Carrier-Grade Chassis, type 7385, any model, any xxx
Lenovo Flex System Enterprise Chassis, type 8721, any model
Lenovo Flex System Enterprise Chassis, type 8724, any model

The system is configured with one or more of the following Lenovo Option part number:

Lenovo Chassis Management Module II, any 00FJ669

This tip is not software specific.

The following system firmware level(s) are affected: All build including 1AON02C.

The system has the symptom described above.

Solution

This behavior is corrected in CMM2 Build ID: 1AON04A.

The file isÂ Â 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

Use the Advanced Settings Utility (ASU) or UEFI to change boot sequence.

Integrated Management Module (IMM) reset will allow CMM to read the boot sequence information, but change still needs to be performed via ASU or UEFI.

Additional Information

CMM internal command to change node boot sequence is not getting applied to IMM correctly.
