Re: Replace faulty/broken disk in NetApp

Ok, well it definitely doesn't recognize the disk. Either try to reseat the disk - take it out, wait 30 seconds or so, and replace it. But if the disk isn't a refrusbished or new NetApp disk it won't accept it and could cause issues. It has to have a NetApp part number on the label somewhere to be compatible.

Re: Replace faulty/broken disk in NetApp

I already re-inserted the disk yesterday and also had error "[DC2NC001:disk.init.badSectorSize:error]: Disk 3d.13.10 has an unexpected sector size (512 bytes) and cannot be used."

Sysconfig -a shows below output

 

 17.14: NETAPP X999_S15K7__4160 000B 56.3GB 512B/sect (Failed)

               

I just copied one line from the sysconfig -a output and have pasted above just fyi. If it's showing the disk as above that means it's recognized, isn't it? I toghut if it's showing the disk info under sysconfg -a that means disk is recognized.

 

The replacement disk is in shelf 17, bay 14

As per the sysconfig -a, it shows disk lablled as NETAPP, however, it shows 512/sect size, and existing disks are 520/sect size, would that be issue?

the new disk is not from Netapp just bought it from our vendor, it's size is 600GB and all existsing disks size is 450GB.

 

 

Re: Replace faulty/broken disk in NetApp

Hi Nutan,

Disks attached to the NetApp storage controllers cannot be used by Data ONTAP unless it meets certain requirements. The firmware level is one of them and is very important. NetApp hardware such as SAS HBAs, intelligent cables, ACP processor, Shelf IO modules etc, need to communicate with the disk to determine the status of disk. At some point, Data ONTAP need to have read and write access to the firmware itself, in order to do certain adminstrative tasks. For example, if a disk fails for some reason, like the number of bad sectors excceding the allowed thresholds, the information regarding the failure will be written to both Data ONTAP Failed Disk Registry (FDR) as well as the "failure bytes" inside the firmware. Also, while booting or detecting the attached disks, Data ONTAP needs to read the firmware to make sure that the "failure bytes" are clean. Otherwise the disk will be considered as failed and will not be used as even a spare disk. Further, each controller and disk shelf can support only limited types of disks. Physical sizes and shapes, capacity, protocol used etc does not necessarily guarantee that the disk is usable on a NetApp controller. You can get a list of supported controllers, disks, shelves and firmware versions for each version of Data ONTAP from the hardware universe at https://hwu.netapp.com.

In short, this disk cannot be used on a NetApp storage controller. You may probably connect that to a server's local HBA and buy a supported disk from NetApp.

 

Hope that helps.

Re: Replace faulty/broken disk in NetApp

Thanks for your reply!

Yes, firmware level on this disk is different than the existing disk and I think that could be the reason it's still showing as BROKEN in the OnCommand console. We don't have supprt with NetApp to purchase the disk from them. So I need to purchase it and replace it.  I am new to NetApp so don't know excat process to replace the faulty disk. All I did is bought new disk from the vendor with same speed howeevr, size is bigger than the existing disk. Could you please tell me what is the exact procedure to replace faulty disk? We had two failed disk and I just bought one new disk and have repalced it and I haven't purchased the second disk yet.

All I did is, removed faulty first disk, inserted new disk, confirmed disk auto assign option is on, so assumed that it should be automaitcally assigned to the controller, othertahn this I didn't run any other command, so please advise if I am missing anything here.

 

so please advsie:

how to update formware on one disk in neatpp?

exact process to replace the faulty disk in netapp? the new disk is not from NetApp so please advsie the procedure accordingly.

 

 

 

Re: Replace faulty/broken disk in NetApp

You have to purchase a NetApp disk - either from NetApp directly or through a third-party. No other type of disk will work in the filer. If you don't have support, you will have to pay the full price.

Re: Replace faulty/broken disk in NetApp

Hello, I've a broken drive 300 GB 15K and need to know if I can use a 600 Gb 15K. This Cluster already have 600 GB 15 K in other shelfs and the drive I will use is a NetApp original spare drive. Can I use it for the replaceemnt?

 

Thanks,

Barata

Re: Replace faulty/broken disk in NetApp

Yes, you can, but disk will be down-sized to 300GB, you will not be able to use full capacity as long as disk remains in raid group with 300GB disks.
