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.

I-errors related to Intel-based blade servers

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-errors related to AMD-based blade servers

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
