Hi Corey,
Im framing a IPMB message and sending it to the remote chassis on the same
enclosure.
I am sending the IPMI message to IPMB bus as follows,
ipmb_addr.addr_type = IPMI_IPMB_ADDR_TYPE;
ipmb_addr.channel = 0; // primary ipmb
ipmb_addr.slave_addr = 0x8a; // remote blade ipmb address
ipmb_addr.lun = 0x02;
req.addr = (unsigned char*)&ipmb_addr;
req.addr_len = sizeof(ipmb_addr);
req.msgid = 1;
req.msg.netfn = IPMI_NETFN_APP_REQUEST;
req.msg.cmd = SEND_MESSAGE;
unsigned int data[1024];
unsigned short len = req.msg.data_len;
// build IPMB message structure
data[len++] = 0x8a; // rs.SA
data[len++] = 0x2c; // NetFun // picmg netfn
data[len++] = 0x1e; // Checksum1
data[len++] = 0x20; // rq.SA
data[len++] = 0x06; // rqSeqNum 7-2 bits+ rq.lun 1-0 bits
data[len++] = PICMG_GET_ADDRESS_INFO_CMD;
req.msg.data = data;
req.msg.data_len = len;
then ioctl sysem to call to send the message. How to receive the
response from the BMC.
here I am getting 0xc3 timeout error.
Thanks,
Thiru

You don't give enough information for me to understand exactly what you are
doing, but there are some problems with what you have done. The driver
handles doing the get message automatically, you don't have to do anything.
All you need to do is send your original command and wait for the response.
