I-error messages displayed for an Intel-based blade server

I-error messages are displayed in the advanced management module event log. Use this procedure to resolve problems that cause I-error messages.

Problem​

The advanced management module event log displays I-error messages for one of the Intel-based blade servers.

Investigation​

Perform these steps to resolve the problem:
  1. For the I-error message, look at the third hexadecimal character from the right. In the following example, the third hexadecimal character is a 4:
    I BLADE_01 03/10/04 14:13:01 (SN#ZJ1TS1234567) 00151352 MachineCheck 
                Data Status: A2000000 8C010400
  2. If the third hexadecimal character from the right is 1, 2, 3, 8, 9, a, or b, replace the CPU on the blade server.
  3. If the third hexadecimal character from the right is 4, 5, 6, 7, c, d, e, or f, the problem is with the communication between the CPU and an I/O device (the I/O data stream has stalled).
    1. View the operating system logs and search for hard disk drive errors. If the timestamps for the hard disk drive errors in the system log correspond to the timestamp for the I-error in the event log, the problem may be with the hard disk drive.
    2. Update all firmware for the blade server. This includes the Ethernet, Ethernet expansion cards, Fibre Channel expansion cards as well as the BIOS and service processor (BMC).
    3. Reseat all expansion cards and the storage expansion unit (if installed) on the blade server. See the blade server documentation for information on reseating blade server components.
      Note
      Make sure that you shut down the blade server operating system before you attempt to reseat the blade server
    4. If the blade server storage expansion unit is not installed, verify that the blade storage expansion (BSE) terminator is installed. The BSE terminator ships with the blade server.
    5. Start the blade server on-board diagnostics (press F2 during POST and run diagnostics). For more information about running diagnostics, refer to the documentation that was provided with the blade server.
    6. Determine what is being stressed when the failure occurs. If the failure only seems to occur when performing I/O over one of the expansion cards, replace the expansion card.
    7. Contact IBM support.
