How can I get rid of an 4K sectors LUN ?

Hi,

On our equallogic newly upgraded there is an option to create 4k sectors LUN's

I did so and I presented this to the esxi.

It is detected, but I can't use it as DATASTORE

The reason is simple, no support of 4k sectors by VMWare.

My mistake !

But the lun is seen under devices ...

so I looked at VMware KB: Unmounting a LUN or detaching a datastore/storage device from multiple VMware ESXi 5.x hosts

I wanted to detach it ... I can't

Basically it makes 3 checks

it takes times on "The device does not contain a diagnostic partition" which makes sense, since it can't access it

The status is on, so I wanted to turn it OFF

esxcli storage core device set --state=off -d naa.6090a04890f7de8e65353568970bc0f2

and I can't turn it OFF

I went "forward" and looked at

VMware KB: Troubleshooting the Add Storage Wizard error: Unable to read partition information from this disk

But

partedUtil delete "/vmfs/devices/disks/naa.6090a04890f7de8e65353568970bc0f2" 1

gave an error.

Basically: I want to get rid of this lun the cleanest way possible

Help

Regards
