New space added to a data store not showing as option to expand in vCenter

[pbalderos]

Hello All

I increased one of our datastores from 13.8TB to 15Tb but when I go to increase the size of the datastore I see the new amount in the "capacity" screen but the option to add the new space does not come up. My SAN is a EMC VNXe 3200 and normally I don't have to do anything because the storage is automatically increased through an API call from the SAN into my vCenter. Any thoughts? I already tried scanning for new datastores and and the HBA

What version of vCenter and Esxi?

[pbalderos]

Its ESXi 6.0 for both

[admin]

if you have esxi host in cluster then Rescan all hosts from vCenter Server.

[dekoshal]

Try This command on esxi host

vmkfstools --growfs "/vmfs/devices/disks/device:partition" "/vmfs/devices/disks/device:partition"

Note: Replace the device:partition with the Device/LUN ID and partition number in your environment respectively.

Thanks for the response. I don't often go in the command line but I think I identified the partition number but not doing to well getting the device ID. Could you give me the command to get the device/ LUN ID and partition number.

I rescanned the cluster several times already.

Can you login to a host directly (using vSphere client) and check if you are able to expand from there. Look at this KB VMware Knowledge Base

Bingo!! Ugh :smileyblush: I should have known better because I had to do the same thing almost a year ago.
