Changing the HDD in netapp and assign the same as spare

Some times we used to face HDD failure in netapp and the role of the failed HDD will be taken care by the spare HDD(Raid 4 setup). So the system will throw the error as "Not enough spare disk" So in this case we have to change the failed HDD with a new one ( should be same size and make with the parent one).


If we check the ONTAP gui the failed HDD will show as broken state (0c.00.6)

 

So first we need to remove the faulty HDD using below mentioned command


#Remove –w 0c.00.06


Then identify the physical disk in the netapp mounted rack which have lights off and remove the HDD physically from the controller .


Insert the new HDD in the same location and wait till the light become green.


Then run the below commands through console ( ssh or telnet)


#priv set advanced


# disk assign 0c.00.06 -s unowned -f


So disk will become orphan state , and next we have to assign the same as spare


#disk unfail -s 0c.00.06


So once we check in GUI we can see that the disk which was in orphan state was assigned as spare to the same controller .


(below case it was 0c.00.2)
