Asked on 17/1/2003, 5:17

hi,

I have an IBM RS/6000 type 7011 model:200 that runs AIX 4.3.3

- My problem is that system without any visible reason stops with ledcode 185. After restart it works perfect.

- From other side sometimes it stops with blinking 888. Thank after pressing the reboot button appears 102, 300, 0c4 codes on the led display. After restart it works perfect.

I have a feeling that it might be some hardware error, but I am not sure.
I would really appreciate your opinion.

Regards,
Z

Hi Z,

IBM Servers arn't my specialty, but I shall try to be of assistance.
LED 185 can be caused by one of two things:

1. Attempt access to a memory address that doesn't exist or
2. A fatal memory error

This could, as you say be a hardware problem, possibly faulty memory.

When you get LED 185, 186 or 187 you should check in the system error report upon startup for "CHECKSTOP". This will confirm that a Checkstop has occured on the system.

The IBM Knowledge base that goes with this fault is: http://www-1.ibm.com/support/docview.wss?rs=0&context=HW130&q=185%2Bled&uid=aix12b04ff3cc8b6d8e9852568160069fefa

------------------------------------------------

LED 888 relates to a completely different set of faults, which usually do not have anything to do with Memory.

If you are running SNA, I recomend reading this article from the IBM Knowledge Base: http://www-1.ibm.com/support/docview.wss?rs=0&q=led%2B888&uid=aix1bc1459eebc52a8eb85256816006a0513

If you are not, I would recomend browsing the search results I came up with for LED 888 at: http://www-1.ibm.com/support/search.wss?rs=0&apar=exclude&q=led+888&tc=&Submit.x=57&Submit.y=9

888 appears in most cases to relate to a software hang/crash so without knowing the particular software on your server it would be difficult to make a complete diagnosis.

In relation to 185 and 888, you are definately dealing with two different problems, one hardware and one software.

Hope this helps!

If you require any further assistance, please feel free to reply to this message. Please include all previous emails so that we may more easily track your problem.

Regards,

-Lawrence Stromski, Helpforce.
