First to answer your question >>Is it possible to bridge Ipmi Commands from IPMB-L to IPMB-0. ? the answer is yes. The AMC.0 spec (defining the AMC carrier behavior) explicitely requires explicit message bridging capability on the carrier. ¶ 140 The Carrier IPMC also supports message bridging to the Shelf Manager from an MMC.
When the Carrier IPMC receives a "Send Message" command to IPMI messaging Channel 0 from an MMC, it extracts the message and redirects the command to the Shelf Manager over IPMB-0. If the Shelf Manager's response is received, the Carrier IPMC reformats the response and sends it to the MMC. I'm not sure if all implementations support that correctly however. To test it, try a supported command instead (such as "mc info" or "picmg addrinfo") . Maybe the parameters you specify are wrong. "ipmitool -t 0x20 -m 0x7a mc info" or "ipmitool -t 0x20 -m 0x7a picmg addrinfo" What carrier/amc are you using ?

Basically I am sending IPMI commands from AMC on a carrier blade to the Shelf Manager. I am trying something similar to below, ipmitool -t 0x20 -m 0x7a raw <Send Message Command to Shelf Manager> where, 0x7a: AMC Address on IPMB-L -t 0x20: IPMC of Carrier blade I am hoping the IPMI commands traverse following path, System Interface on AMC -> IPMC present on Carrier Card, IPMB-L -> Shelf Manager, IPMB-0 Does the IPMCs on Carrier blade have bridging Capability? From IPMI v1.5 spec it seems that only BMC (Shelf Manager) has the bridging capability. If it is possible to bridge commands from IPMB-L to IPMB-0, please point me to the details of parameters to Send Message Command. -- Raghavendra G OpenClovis Solutions, Bangalore +91 9880213025 -- Raghavendra G OpenClovis Solutions, Bangalore +91 9880213025
