Symptom

Before upgrading the PSU Option of a ThinkSystem DW612 enclosure with chassis type BF7K (6x PSU + 3x PSU Cages) from 6x 2400W to 9x 2400W PSU for SD650-N V2 servers, use SMM2 OEM IPMI commands listed in the workaround section to set the chassis type to BF7L (9x PSU + 3x PSU Cages).

Note:

1. DW612 enclosures with 7 or 8 PSUs are not supported.
2. Only Delta 2400W PSUs are supported.

(where PSU = Power Supply Unit, SMM = System Management Module)

Affected Configurations

The system may be any of the following Lenovo servers:

• ThinkSystem DW612 DWC Enclosure, Type 7D1L, any model
• ThinkSystem SD650-N V2, Type 7D1N, any model

This tip is not software specific.

This tip is not option specific.

The system has the symptom described above.

Solution

This behavior is corrected in SMM2 version 1.02 or later version.

The file is available by selecting the appropriate Product Group, type of System, Product name, Product machine type, and Operating system on Lenovo Support web page, at the following URL:

Please also refer to the workaround section for chassis type update.

Workaround

Please follow the steps below for enclosure type change:

1. Enable SMM2 IPMI interface via XCC (by default, network is enabled but IPMI is disabled).
   ipmitool -I lanplus -H [XCC_IP] -U [USERID] -P [PASSWD] raw 0x3A 0xF1 0x04
2. Read the enclosure type.
   ipmitool -I lanplus -H [SMM2_IP] -U [USERID] -P [PASSWD] raw 0x32 0xC8 0x01
   The return value should be 0x02, which indicates the current enclosure type is type 2.
3. Configure the enclosure type.
   # Set Chassis Type 3
   ipmitool -I lanplus -H [SMM2_IP] -U [USERID] -P [PASSWD] raw 0x32 0xC8 0x00 0x03
4. Read the enclosure type again.
   ipmitool -I lanplus -H [SMM2_IP] -U [USERID] -P [PASSWD] raw 0x32 0xC8 0x01
   The return value should be 0x03, which indicates the current enclosure type is type 3.
5. Reset SMM2 to make the configuration take effect.
   ipmitool -I lanplus -H [SMM2_IP] -U [USERID] -P [PASSWD] mc reset cold
6. After SMM2 reboots, disable the SMM2 IPMI interface via XCC.
   ipmitool -I lanplus -H [XCC_IP] -U [USERID] -P [PASSWD] raw 0x3A 0xF1 0x01
   Note that incorrect operation may cause unexpected behavior of chassis management (e.g. executing a wrong command). Please carefully use this command.

(where XCC = Lenovo XClarity Controller)

Additional Information

The DW612 enclosure supports three chassis types. For users of chassis type BF7K that have purchased additional PSU option parts to upgrade, the chassis type will need to be manually set to 3 as SMM2 does not automatically detect the newly installed PSU and set the correct chassis type.

The workaround provides the solution to manually set the chassis type correctly. However, this approach does not allow the setting changes to be traced and controlled.

Since version 1.02, SMM2 will log the command used in setting the chassis type and will identify the current chassis type and control the changes that can be made.
