Troubleshooting Shared memory communications direct issues

To display SMC-D statistics, information about the active SMC sockets, and the error codes use smcd and smcss commands.

  1. Display SMC-D statistics. 
    # smcd stats
  2. Check information about the SMC sockets. 
    # smcss
    An example of the SMC-D connection is as follows:
     ACTIVE 00000 1497454 172.20.145.18:1191 172.20.145.20:39900 0000 SMCD
    An example of the TCP/IP connection, which fell back, is as follows:
    ACTIVE 00000 0129066 10.20.82.10:36169 10.20.82.8:1191 0002 TCP 0x05000000/0x01010000
  3. Check the error message for the TCP error code. 
    # man smcss
    A sample output is as follows:
     ...
 Linux error codes:
 ...
 0x05000000 Peer declined during handshake
