MD3200i - Failed disk, hot spare didn't swapping in + unreadable sectors

Hello all,

 

I have an out of warranty MD3200i with a failed disk. The hot spare didn't swap in, and I'm getting unreadable sectors.

There's a single disk group, with 8 virtual disks, and one of the virtual disks is showing as degraded. There's a reconstruction in progress, but it's failing continuously.

The following disks have a non optimal status in MDSML

Slot6 - Replaced - this was previously the hotspare

Slot 7 - Failed.

Slot 10 - Impending failure.

The raid level of the disk group is 5.

 

I've collected the support data.

 

Brian

Hi,

Can you private message me the service tag so we can get some additional information?

 

If it is failing the rebuild due to the drive with bad sectors you are going to need to replace the bad drives, create a new array and restore a backup. http://www.dell.com/support/article/us/en/4/SLN111497

Re: MD3200i - Failed disk, hot spare didn't swapping in + unreadable sectors

The virtual disk is a cluster shared volume in a hyperV cluster - I have a backups at the guest OS level, but not at the LUN level.

It's still operational, so I can assign a driver letter in the cluster host and take a backup of the virtual disk data that way when all the VMS are shutdown.

Recovery guru is only showing one virtual disk as degraded - I was unsure if other virtual disks were affected (i.e. did I need to back up the full storage array).

Can I get a quote for a replacement disk, or disks?

Is there any alternative to deleting the virtual disk?

 

Is it possible to tell whether the disk will continue to degrade to the point where the virtual disk will go offline?

 

Thanks.,

Brian

If it is not rebuilding there is not another way around recreating the array, since the bad blocks on the drive are preventing the rebuild. Unfortunately, I am not able to do quotes, it has to come from the sales department.

Thanks Josh,

Is it possible that only one virtual disk is affected?

Yes, it depends on where the bad blocks are located, they could all be in one virtual disk.

Hi Josh,

 

Would it be possible for someone to have a look at the support bundle so that I can be sure that the correct drives are replaced?

 

Thanks,.
