Hi Ashwin,

As this point you need to get the disks replaced to avoid your controller shutodwn as i see your controller is already running in DEGRADE MODE ( NetApp goes to degrade mode if more than 2 disk failure)

Could you help to post output of commands

vol status -f and vol status -s ?

If this is a cluster mode controller then use command

storage show disk -broken

storage show disk -spare

Thanks,

Nayab

Hi Nayab,

Thanks for your reply.

Please find the attached files.

Please let us know if the data is lost as we cannot access the volume from the Server.

Hi Ashwin,

I see from the logs that takeover failed due to no enough spares, I suggest to replace the failed disk and power on the system again it should come up.

Thanks,

Nayab

Hi Ashwin,

I can see one spare disk available in the spare pool, but i would suggest replacing all the failed disk and power on the controllers.

Thanks,

Nayab

Hi Nayab,

Thanks for the advice.

However we are unable to access Filer 02 in which there is 4 disks failed.

Will the date in Filer 02 be lost. Please advise

Hi Ashwin,

At this point i cannot confirm that because if all the disks are data disks then you can still rebuild your data from parity. But imagine if two parity disks failed the definetly there will be data loss. That is the reason why i have asked to replace the disks asap and power on the controller and allow Ontap to rebuild all the failed disks, If all rebuilt then you can still have your data.

Thanks,

Nayab
