After you finish

  1. When the status LED on the SMM2 goes from fast blinking to slow blinking, it indicates the SMM2 is ready to work. However, if the status LED is off or continuously lit, it indicates the SMM2 has encountered one or more problems.

  2. Check the power LED on each node to make sure it is on.
  3. If shared I/O adapters are installed, complete the following steps to make sure the enclosure supports shared I/O.
    1. Enable SMM2 IPMI interface via XCC with the following command (Default setting is network enabled but IPMI disabled).
      ipmitool -I lanplus -H [XCC_IP] -U [USERID] -P [PASSWD] raw
      0x3A 0xF1 0x04
    2. Query the current enclosure mode with the following command:
      ipmitool -I lanplus -H $SMM2_IP -U $USERID -P $PASSWORD raw 0x32 0xC5 0x01

      response data
      byte 1: current mode
      01: Normal mode
      02: Shared I/O mode
    3. If the enclosure is in normal mode, configure the enclosure mode to Shared I/O mode with the following command:
      ipmitool -I lanplus -H $SMM2_IP -U $USERID -P $PASSWORD raw 0x32 0xC5 0x00 0x02

      response data
      byte 1: previous mode
      01: Normal mode
      02: Shared I/O mode
      byte 2: current mode
      01: Normal mode
      02: Shared I/O mode

  4. Make sure you follow the guidelines in PSU configuration.
