Part II: How To Create A LUN With EMC Unisphere & Allocate It To An Existing Host

By September 7, 2011EMC, How To

Awhile back, I wrote a blog explaining how to create a LUN for ex-Navisphere users – here I will go more in depth with the procedure, as we are binding in this instance. Hence, in this procedure we will be “binding a LUN” from an existing RAID group or pool and allocating it to an existing storage group.

Let’s begin, starting with:  

Logging into Unisphere:

  1. Open IE or another internet explorer application.
  2.  

  3. Type in the IP of the Control Station or Storage Processor:

              a) http://<IP of array>

     3.    Type your username and password when prompted and click login.       

             a) EMC default sysadmin – sysadmin.

     5.       a)  Type in the size of the LUN in the “User Capacity” field.

                b)  Select the ID you want the LUN to have. 

                c)  To commit select “Apply”.

                d) Optionally select “Name” to give your LUN a name instead of an ID.

                e) If you want to create multiple LUN of equal size select “Number of LUN to create”.

OPTIONAL: If you want to specify which FAST tiering policy select the “Advanced” tab, and specify which policy. Note this option can only be configured with LUNs that are in a pool.

 Adding LUNs To Existing Storage Groups

  1. Right-click the LUN and Select “Add to Storage Group” to allocate newly created to an existing:

      2.    Select the “Storage group” you wish to add the LUN to. 

              a) Click on the forward arrow and Click “OK”.

              b) Optionally you can select multiple “Storage Groups” for multiple hosts allocation.

You have now allocated the LUN to your existing host. Refresh your hosts Disk Manager Application to rescan for devices, partition the devices, and create volumes or Datastores using your OS disk provisioning tool.
