EMC Symmetrix VMAX Provisioning a LUN

Posted on 09/09/2014 by vcdx133

(http://vcdx133.files.wordpress.com/2014/06/vcdx133e1403379365573.jpg) This post coverhow to provision a LUN (less than 239GB) for vSphere on an EMC Symmetrix VMAX using theUnisphere for VMAX GUI. The basic architecture of the VMAX is covered here(http://wp.me/p4znjP4b). If you want to build LUNs greater than 238GB, you follow the sameprocedure, but with the additional step of creating a Meta Volume (multiple TDEVs bound to asingle logical volume).

Summary

Create the LUN TDEV (Thin Device)Create the Storage Group and bind the TDEV to itCreate the Initiator Group with the ESXi HBA WWPNsCreate the Masking View and bind the Storage Group, Port Group and Initiator Group to itAppendix Set Port Attributes for vSphere

Prerequisites

You have administrator access to the EMC Symmetrix VMAX and Unisphere for VMAX GUI.EMC Symmetrix VMAX Enginuity code 5876.268.174 with EMC Unisphere for VMAX version

1.6.0.8.Symmetrix VMAX is being configured for Virtual Volumes with FASTVP, not RegularVolumes and FASTDP.You know your storage environment, in particular, how to zonethe SAN Fabric and whichVMAX Front End Ports are being used for your ESXi hosts.This procedure breaks the tasks into their most basic steps, you can also use the ProvisionStoragewizard in the Common Tasks section on the right of the GUI. Symmetrix VMAXgurus also use symcli to script via CLI not covered here.

Create the LUN TDEV (Thin Device)

1. Open a Web Browser and connect to the Unisphere for VMAX GUI: http://

Bind to Pool FC R10 or R6. Then select Run Now.8. Record the serial number (0C08 in this example) of the volume when the Successfully

created window appears. Press the Close button.

1. Press the Hosts icon and then the Masking Views object.2. In the Masking Views window, press the Create button.3. In the Create Masking View window, enter the Masking View Name (add _MV for

clarity), Initiator Group name from the previous step, the selected Port Group that is zoned tothe ESXi Host and the Storage Group name from the previous step. Then press OK and thepress Close.

4. You LUN (TDEV) is now ready for use. Make sure your SAN fabric has zoned the ESXi Host

HBAs to the Front End ports of the VMAX as per the Masking View just configured.

Appendix EMC Symmetrix VMAX Set Port Attributes for vSphere

The Front End Ports of the VMAX require a specific set of Port Attributes to be configured tofunction with vSphere. This should already be configured as part of the Symmetriximplementation, but here it is anyway.

1. Press the System icon and then the Front End Directors link in the Hardware section.2. Select each of the Front End Director objects that is being used with vSphere FAxxy and

press the Set Port Attributes button.3. Make sure the following Port Attributes are Ticked: ACLX, Common Serial Number
