Who knows the BMC I2C address?

We try to use the userspace utility i2ctransfer to send the NVMe-MI command to SSD.

We know the destination I2C address is 0x1d, but when the SSD responds to BMC, we don't the BMC I2C address, the example is as below:

root@pcomc660:~# i2ctransfer -y -f -v 1 w11@0x1d 0x0F 0x08 0xE1 0x01 0x00 0x00 0xC8 0x00 0x80 0x02 0x2C r12;
Error: Sending messages failed: No such device or address

The "0xE1" means response address, but we don't know the correct BMC I2C address, so there are no response messages.

Could someone else tell us how to find the correct BMC I2C bus address?
