removing a LUN from a 2008r2 server

Hi, years ago I added a LUN to a 2008R2 server - its on a 1200i.
I’m not using it currently.

I believe it was added with the ISCSI initiator, I’m wondering the easist way to disconnect it permanently?

Can I use drobo dashboard?

Thanks Andy

I believe the Dashboard will let you remove the volume from the Drobo, including erasing the data.
You can disconnect it the normal way in Windows. (I’m using Win7, but 2008R2 should be similar). Control Panel, Administrative Tools, iSCSI Initiator, look in the first tab Targets and you’ll see something like “iqn.2005-06.com.datarobotics.blahblah” listed. Select it and click the Disconnect button.
