I-error messages

I-error messages are displayed in the advanced management module event log. They occur any time the CPU on the blade server encounters a problem on the system. Typically, they are the result of a nonresponsive I/O device.

The root cause of most I-errors is normally one of the following:
  • I/O device drivers
  • Hard disk drive failure
  • PCI device timeout
  • Non-terminated SCSI bus
  • Real CPU internal failure
  • Power supply problems
The following example shows I-error messages:
E BLADE_01 03/10/04 14:13:02 (SN#ZJ1TS1234567) PFA Alert, see preceding error 
                 in system error log.          
E BLADE_01 03/10/04 14:13:02 (SN#ZJ1TS1234567) 00151200 MCA: Unrecoverable Error
                 Detected Proc=1          
I BLADE_01 03/10/04 14:13:01 (SN#ZJ1TS1234567) 00151352 MachineCheck Data Status:
                 A2000000 8C010400

I-errors result when the CPU encounters a machine check error that cannot be recovered. Most often, these errors are memory errors, but occasionally they can be related to the processor. When a machine check error occurs, you will need to restart the blade server.

Below is an example of a memory error on an AMD blade server reported in the advanced management module log:
I       BLADE_07     08/24/06, 17:40:53 (id14c2n07) Power unit power off event received 
E       BLADE_07     08/24/06, 17:38:25 (id14c2n07) POSTBIOS: 289 DIMM D02 is Affected.
E       BLADE_07     08/24/06, 17:38:25 (id14c2n07) POSTBIOS: 289 DIMM D01 is Affected.
E       BLADE_07     08/24/06, 17:38:25 (id14c2n07) Memory disabled: DIMM number 2  
E       BLADE_07     08/24/06, 17:38:25 (id14c2n07) Memory disabled: DIMM number 1
