Unable to see extra space after LUN resized

bogdan — Wed, 04 Jun 2025 13:16:27 GMT

Hello,

I have resized a LUN to increase the capacity within filer, but the newly resized amount is not seen when trying to increase the VMFS datastore within VMware. Tried to rescan the storage adapters but the issue persist .

Thank you

Hi Bogdan,

How are you doing?

I hope you did:

1)Resize the LUN in NetApp

2)Rescan from vCenter, may not be required all the time

3)Right click on the datastore >increase Datastore capacity>complete the wizard

4) You should be all good

If not can you please double check the LUN ID and make sure that you expanded the correct LUN by comparing the ID?

The serial number of the LUN can be seen using the below command from ONTAP CLI

cluster::>lun show </vol/lunpath> -fields serial-hex

Also make sure that your Hyperviser supports the increased disk size.

Hope this helps!

Cheers,
