Running Systems

When using ‘disk show -v’ on a NetApp filer version 7.3.x, following replacement or addition of disk(s), you might see the above mentioned message. It is caused by incorrect disk label – of OnTap version 8, on an OnTap version 7.3.x system. The system cannot handle the incorrect label, and thus – ignores the disk.

A set of actions is required to clean the label and allow the NetApp to use this specific disk. The easiest method (although it will not be described here) would be to place the disk back in an OnTap 8 NetApp device, and clean the label from there, however, it is not always possible.

On your OnTap 7.3.x system, do the following (assuming you know the address of the disk, right?) – taken from NetApp’s forums here.

disk assign <diskid>
priv set diag
labelmaint isolate <diskid>
label wipe <diskid>
label wipev1 <diskid>
label makespare <diskid>
labelmaint unisolate
priv set

The fifth or sixth lines might fail to run, but still – the process will succeed as a whole.
