Intel MPCMM0001 Remote Procedural Call RPC Interface, Rmcp, Ethernet Interfaces, Retrieving a SEL

Software Specifications

2.5Remote Procedural Call (RPC) Interface

In addition to the console command-line interface, the CMM can be administered by custom remote applications via remote procedure calls (RPC). RPC is covered in Section 19, “Remote Procedure Calls (RPC)” on page 174.

2.6RMCP

RMCP (Remote Management Control Protocol) is a protocol that defines a method to send IPMI packets over LAN. The RMCP server on the CMM can decode RMCP packages and forward the IPMI messages to the appropriate channels including: SBC blades, PEMs, and FanTrays or local destination within the CMM. When there is a responding IPMI message coming from SBC blades, PEMs, or FanTrays destined to RMCP client, the RMCP server will format this IPMI message into a RMCP message and send it to through the designated LAN interface back to originator. RMCP is covered in Section 20, “RMCP” on page 190.

2.7Ethernet Interfaces

The CMM contains two Ethernet ports. The software can configure each of these ports to either the front panel, to the backplane, or to the rear transition module (RTM). Information on configuring the Ethernet interfaces is covered in Section 8.3.1, “Setting IP Address Properties” on page 72.

2.8Sensor Event Logs (SEL)

The AdvancedTCA CMM implements system event logs according to Section 3.5 of the PICMG

3.0 Specification. The SEL contained on the CMM is fully IPMI compliant.

2.8.1CMM SEL Architecture

The MPCMM0001 uses a single flat SEL file stored locally in the /etc/cmm directory. The SEL maintains a list of all the sensor events in the shelf. Each of the managed devices may keep its own SEL records in local SELs, but the master copy for the shelf is maintained by the CMM.

The SEL is limited to 65536 bytes. In order to keep the SEL from getting full, which can cause loss of error logging, the SEL is checked every 15 minutes by the CMM, and if the size of the cmm_sel is greater than 40000 bytes, the SEL is archived in gzip format and saved in /home/log/SEL. The names of the saved logs will be cmm_sel.0.gz, cmm_sel.1.gz, and so on, to a maximum of 16 logs where they are then rolled over.

Note: Archived files should NEVER be decompressed on the CMM as the resulting prolonged flash file writing could disrupt normal CMM operation and behavior. Using FTP, transfer the files to a different system before decompressing the archive using utilities such as gzip.

2.8.2Retrieving a SEL

To retrieve a SEL from the CMM, issues the following command:

cmmget [-l location] -d sel
