Memory hardware error(HPMC detected)

[srinivas_30]

Hi,
I tried to boot up a A500 HPUX system. The initial Hardware checking gives this error. This doesnot seem to be a fatal error because if I acknowledge this error, the hardware test continues and boots up fine. After booting up, I ran the STM and ran the exercise tool on memory to figure out what is wrong. The tool completed successfully with out any errors. I tired to change my memory Modules with another set of memory modules I have. I still get the same error. Can any one out there please email me what this error means? Thanks in advance for your help.
Here is the error:
memory error handler 0AC3 [Failed with Alert Level = 7]
Chassis Code Encoded Field = 0x7000077070ffac34
Alert Level = 7 (HPMC detected.)
Source FRU = 7 (memory)
Source FRU Detail = 0 (unknown, no source stated)
Source ID = 255 (platform dependent)
Event Detail = 0 (unknown, no source stated)
Caller Activity = 10 (error handler)
Caller Subactivity = 195 (implementation dependent)
Activity Status = 4 (implementation dependent)
Reporting Entity Type = 0 (system firmware)
Reporting Entity ID = 0
Data Type = 14 (problem detail)
Message ID = 7
Chassis Code Data Field = 0xc380800000000000

Thanks,

Hi

Can't offer much advice except to point you towards the rp24xx (new name for A400/A500) hardware manual.
http://docs.hp.com/hpux/onlinedocs/2411/rp24xx_customer.pdf

This has a section on troubleshooting the server (Chp8), chassis codes etc

I've also attached an old A-Class User Guide which has some info on HPMC errors.
Hopefully you might find something in there that can help.

The Chasis codes are difficult to decode & I'd be inclined to log a call with HP. Even though you can identify its a memory problem, it may be related to the controller on the system board rather than the DIMMs themselves, hence changing the DIMMS will still give you errors.

Cheers

Hi Srinivas,

You haven't mentioned the PDC version but I think the problem will be the same.

If the error is EXACTLY the same after you replaced the memory or at least swapped them around, then I would suspect you may have a faulty system board.

Otherwise, you have still recorded an HPMC which is pointing at hardware. I would log a call and have HP check it out.

Cheers!

Srinivas -
Unlike LowPriorityMachineChecks, this needs immediate attention. A call to HP support would definitely be inorder.

Best of luck.
