Please, what I should do to fix the problem?.

 

Thank you.

 

Re: "Disks are currently unowned" imposible to change its state or assign.

SCSI code 4, 44/0 means "Hardware Error - internal target failure" . This drive 1d.19 ( 4th drive from the right side of the 1st shelf , assuming its a DS14 shelf ) is bad. Get it replaced. Also please monitor if this error re-occurs on the same slot.

Hi,

Thanks for you response.

We already replace de drive (twice) but we still with the same problem. The field engineer replace the drive and the drive goes directly in "amber".

 

Please, do you have some idea? what we can do to fix it?

 

Thank you.

 

Cheers.

 

Re: "Disks are currently unowned" imposible to change its state or assign.

This error is on a single disk?

Is this happening on the same disk every time? (I mean disk xx.19) 

Also, what is the FAS / Shelf models?

Did you check with NetApp tech support ? If yes what was their response?

Hi,

Yes, always is the same disk

 

Also, what is the FAS / Shelf models?

FAS3140

Shelf models:

vendor identification=XYRATEX
product identification=DS14-Mk2-AT

product revision level=3838

 

Did you check with NetApp tech support ? If yes what was their response?

No, I didn't because even I don't now if we have NetApp support (I think we don't). We have a service from external company and they said that we have to restar the controllers but they don't send to me a procedure (so I don't trust in them) and I am not confident to restart the controllers just looking in internet to do it so any help would be very apreciated because as you maybe realize my knowledge of this system are minimun.

 

Thank you very much for your help.

 

Cheers.

 

Re: "Disks are currently unowned" imposible to change its state or assign.

There are many things to consider in this case, which can be only confirmed by looking into the historical autosupport and case data for this system. Thats why I suggested to contact NetApp Tech support. However, from what you explained, I understand that either the ESH module B (on the bottom of the first shelf) or the backplane port on bay#3 (4th slot form the right) on that shelf may have a physical error. It can be as simple as a loose connection or as bad as a hardware fault. Since the drives are going to maintenence center, I am assuming a temporary transport error might have happened. 

The first step of troubleshooting is to remove and re-seat the ESH modules and cables. But since you have an AT shelf, removing one of the modules will take half of your Hard disks offline, leading to a panic. So, as your service provoder requested, you need to shutdown the storage controllers, remove and re-insert all cables, connectors, SFPs, IO modules etc, and power everything back on. If the issue still persists, you may have to replace the ESH module, the Shelf Chassis, or both. 

 

Get in touch with the service guys and ask them to help you in doing this. Make sure that you have informed the users, because this may need a downtime of at least 30-40 minutes I guess.

Ok, I will do that.
