30 I2C Read Failure EMC - Backup has been down for 3 days now.

Mike Westmoreland — Sat, 13 Mar 2010 08:36:02 GMT

This SAN's Array is what we use to back up our systems and it's been down for three days now. We're in deep and need to identify what the real problem is here. And what we need to do to fix it. I've tried reseating things and done some parts swapping.

MSA1000
Original msg - 03 Critical lock up detected. code=f215h.

We have a replacement MSA1000, array accelerator 256 mb cache module,the fiber channel io module and fiber cable, that was overnighted in.

Put the original array accelerator cache module into the replacement MSA1000.
Now when we boot up we get the msg 30 I2C Read Failure EMC.
What is the EMC?

I've seen a post saying the EMC may need to be replaced. http://forums13.itrc.hp.com/service/forums/questionanswer.do?admit=109447627+1268465401125+28353475&threadId=1123664

I can use HyperTerminal to connect to the MSA1000, but I have a system msg that constantly scrolls down the screen. Pressing the return key gets me to a cml prompt but only for a moment.

How can I stop this scrolling display? So I can get to the cml prompt. cntrl c does not seem to do it.

I'm hoping this captured text will help someone to help us. Note the difference in firmware levels between the two MSA's.

Did I ask the question the wrong way? I've not gotten a response.

I've since learned that the EMU is the environmental monitoring unit. And that it's attached to the scsi io module.
