VNX: How To Guidelines for Configuring EMC VNX Systems with SAN Volume Controller and Storwize V7000 and V5000 ( SVC ) (User Correctable)

The VNX is provisioned as Block LUNs, and  appear as managed disks (Mdisks) on the SVC, which can use them to create storage pools (MDiskgroups) to provision SVC volumes (VDisks) for use by hosts or for use with tiering.

Example of the VNX controller under SVC;
 vcinfo lscontroller
 id controller_name ctrl_s/n vendor_id product_id_low product_id_high 
""  0 controller0 01543BC1B7CL DGC VRAID ""

LUN Mapping: 
 Mdisks greater than 2TB LUNs are supported with SVC. SVC has a maximum LUN size of 1PB
 
LUN presentation: 
 LUNs are exported through the EMC VNX storage system s available FC ports. SVC's ports must be registered and assigned to a VNX host and the LUNs assigned to this host. 


 Configuration settings for EMC VNX storage system: 
   The Initiators need to be registered; 
   System Name > Hosts > Initiators. 

 Settings: 
 Initiator type; CLARiiON/VNX 
 Failover mode; Active-Active (ALUA) failover mode 4 
 N.B. Legacy failover mode 2 can also be used. 

 Assign all the Initiators to the same SVC host definition. 

 The setup is straightforward, SVC will see the controller without a LUN being presented. Run svctask detectmdisk for SVC to  search the fabric. To verify, run svctask lsdiscoverystatus, this will show inactive when completed.
