How to Create a LUN on an EMC VNX Array w/ Unisphere (for Ex-Navisphere Users)

By May 5, 2011EMC, Storage

As the VNX unified storage array continues to roll out, concerns increase for customers who have known Navisphere for years. For example:

“Where is everything and how the hell do I create a LUN?”

In order to better prepare users for this query and other simple tasks, let’s create a LUN from an existing RAID group.

Let’s start by logging in and selecting the system to be configured:[image title=”Step One” size=”small” align=”center” width=”500″ height=”300″]http://www.integrateddatastorage.com/wp-content/uploads/2011/05/12.png[/image]

Once you select your array you will see the following display:

Best practice for maneuvering around Unisphere is to use the main tabs at the top of the interface: [image title=”3″ size=”small” align=”center” width=”600″ height=”50″]http://www.integrateddatastorage.com/wp-content/uploads/2011/05/31.png[/image]

Now there are two ways we can create a LUN: by highlighting the “Storage” tab and selecting LUN’s as seen below, or by right clicking the RAID you desire from the Pools/RAID Group page. The best way to allocate a LUN would be to select the “Pool/RAID Groups” page under the “Storage” tab, which is one of the task panes illustrated below: [image title=”4″ size=”small” align=”center” width=”500″ height=”300″]http://www.integrateddatastorage.com/wp-content/uploads/2011/05/41.png[/image]

Be sure to select the RAID group or storage Pool you wish to create a LUN from:

As seen below you can tell how much storage is available via a bar graph and free capacity colum—that means no more right clicking on each group to find out how much it can create.

Now right click the RAID group that you wish to create storage from and select “Create LUN”: [image title=”7″ size=”small” align=”center” width=”500″ height=”300″]http://www.integrateddatastorage.com/wp-content/uploads/2011/05/71.png[/image]

This screen has not changed much, the only difference being that now you can name your LUN ahead of time as in the example below. We will be creating two LUN’s at 250GB each, entitled Exchange 2010 DB with a starting ID of 00. This will create two LUN’s with the name Exchange 2010 DB_0 and Exchange 2010 DB_1, then just click apply and done.

Below is the RAID Groups pane. You will have a details pane for each RAID group you select. Highlight all the LUN’s you wish to allocate to a storage group and select “Add to storage group.” [image title=”9″ size=”small” align=”center” width=”500″ height=”300″]http://www.integrateddatastorage.com/wp-content/uploads/2011/05/9.png[/image]

Assuming you have already created a storage group, simply select the storage group and hit the forward arrow. Once you hit “OK” you have successfully created a LUN and added it to an existing storage group. [image title=”10″ siz=”small” align=”center” width=”500″ height=”300″]http://www.integrateddatastorage.com/wp-content/uploads/2011/05/10.png[/image]

I hope this tutorial has helped clear up some of your questions. Stay tuned as we continue to create FAST pools and monitor FAST Tiering.
