Re: LUN Max Resize

No, it's not possible to remove this limitation.  You will need to create a new LUN and migrate the data.

Re: LUN Max Resize

Just providing a little bit more info:

 

Under normal conditions up to 10 times their original size in ONTAP versions prior to 9.5.

 

cDOT:
In ONTAP 9.5, the 10x resize limit was removed.
For cDOT 8.x and ONTAP 9 versions prior to 9.5, this capability (edit) is not present. Instead, a new volume and LUN should be created, and the data migrated to the new (appropriately sized) location.


7-Mode:

You can force (edit) change the cylinder size by running the 'lun attribute set' command (Max:16T | Cylinder_size:271,434,240).


Wonderful KB: Please read it.

16TB limit for LUN, applies to both 7-mode & cDOT irrespective of their versions.

 

Thanks,
