Re: adding disks to EVA8000 enclosure

The disk drive does not have proper contact with the backplane connector, or the enclosure is damaged.

I would first try to re-seat the disk(s), then swap the disk(s) to see if the error walks with the drive or stays at the slot.

Re: adding disks to EVA8000 enclosure

I have double checked that the disks is properly seated on the enclosure. This is what happens (atleast from the disks LED view point): the disks is spun up, quiried and then marked faulty. The disk activity LED blinks and afterwards no activity on the disk.

Re: adding disks to EVA8000 enclosure

It's not clear whether this is happening on all drives that you're installing, and in all slots.

"drive not mated" could sometimes be reported when you have a failed drive. If it's happening with more than one drive, then you're probably looking at a problem with the disk enclosure, or a slot on the enclosure...

Re: adding disks to EVA8000 enclosure

This is happening on all empty slots on the encloure. We randomly selected slots among the eclosures and we get the same results. We have tried using didfferent drives on the these slots. Same results also.

Our VCS fw version 5.020 and CV EVA is verson 4.0 build 53. Just in case this may have a bearing on the case.

Many thanks

Re: adding disks to EVA8000 enclosure

OK. You're versions of XCS and Command View are quite old, but that shouldn't have an impact - unless of course the drives are too new to be recognised...

What model drives are you trying to install...?

Re: adding disks to EVA8000 enclosure

OK. That should be fine...

I think my next step would be to raise a service call with HP. It sounds like you may well have a broken enclosure..

If you remove all the drive blanks can you see any obvious sign of damage on the enclosure back plane ?

Re: adding disks to EVA8000 enclosure

hi, I had the same problem and had to replace the Enclosure. So log a call with HP and they will fix it. ungroup other disks in the enclosure too.

Re: adding disks to EVA8000 enclosure

I logged a call with HP and initially they suspected the disks were logged on the Disk Suspect List (DSL). This is where any buggy item on the EVA is logged. Clearing the DSL is reported to help.

And now they are saying my model of the disks is too recent to be recognised by VCS firmware level.

So I have no choice but to upgrade my VCS and will let you know the results afterwards.

Thanks for all the input

Re: adding disks to EVA8000 enclosure

That does indeed look likely.

If you go through the various disk firmware advisories, the most recent of which I can find is here for XCS 6.000.

http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?objectID=c00801754〈=en&cc=us&taskId=101&prodSeriesId=470490&prodTypeId=12169

That doesn't mention your specific drive model. So it does look as though you'll have to upgrade the XCS code. It looks like the BF1465A477 drive was probably introduced early in 2007, so is a lot newer than XCS 5.020.

Re: adding disks to EVA8000 enclosure

1. I have upgraded to the latest VCS firmware 6.1 and I am still getting the same error. "Drive not mated". This was under the recommendation from HP Competency Center. Are we the only once having a problem with this disk model?

2. I talked to another Storage Engineer about clearing the DSL. He strongly recommends that HP does it as it can corrupt data on the EVA. What is everyone's take on this clearing of the DSL and what exaclty is it?

Re: adding disks to EVA8000 enclosure

To get the disks that were marked as failedto work again you will have to clear the DSL. Until then you will not be able to use that disk drive anywhere in your EVA without it being marked as failed. If you don't know how to do this then get your HP technician to clear it for you.

Once it's in production it's all bugs after that.
