The following points summarize the steps required to configure NPIV:

1. Ensure the HBA, switch, and ESX version support NPIV.

2. Assign a RDM volume to the ESX server and then to the virtual machine.

3. Enable NPIV for that virtual machine to create virtual WWNs.

4. Manually enter the virtual WWNs within the switch interface. Some switches might be able to view

the WWNs without manual entry of the virtual machine virtual WWNs.

5. Zone the virtual WWNs to the CLARiiON storage systems using the switch interface. Add them to the

same zone containing the physical HBA initiator and CLARiiON storage ports.

6. Manually register the initiator records for that virtual machine using Navisphere using the same

failovermode setting of that of the ESX server.

7. Add the virtual machine (host) to the same storage group as the ESX server or assign them to a

different storage group.

8. To add LUNs to the virtual machine ensure that:

a. LUNs are masked to the ESX server and the virtual machine storage group.

b. LUNs have the same host LUN number (HLU) as the ESX server.

c. VMs are defined in different storage groups.

d. LUNs must be assigned as RDMs to each virtual machine

CLARiiON and VMware Site Recovery Manager (SRM)

VMware Site Recovery Manager (SRM) provides a standardized framework to automate site failover in

conjunction with Storage Replication Adapters (SRAs) provided by storage vendors. CLARiiON has an

SRA for MirrorView that works within the SRM framework to automate most of the steps required for a

site failover operation. The EMC CLARiiON SRA supports MirrorView/S and MirrorView/A software for

FC and iSCSI connections.

MirrorView/S and MirrorView/A run on all available storage system platforms, including CX4, CX3, and

AX-4 systems. SRM added support for AX4 storage systems. MirrorView does not consume server

resources to perform replication. Please consult the white paper MirrorView Knowledgebook on Powerlink

for further information about MirrorView/S and MirrorView/A.

RecoverPoint SRA is also supported with VMware SRM; CLARiiON LUNs can be replicated using the

CLARiiON splitter or the RecoverPoint appliance. For more details, please refer to the RecoverPoint

documentation available on Powerlink.

SRM requires that the protected (primary) site and the recovery (secondary) site each has two independent

virtual infrastructure servers. To use the MirrorView SRA, mirrors need to be created, and secondary

LUNs need to be added. MirrorView SRA 1.3.0.4 and later can work with individual mirrors as well as

consistency groups. But as a best practice, if a datastore spans multiple mirrors, it should be put in a

consistency group and placed in a MirrorView consistency group. To leverage the test functionality within

SRM, SnapView snapshots of the mirrors must exist at the recovery site within the proper CLARiiON

Storage Group. (We also recommend that you create snapshots for the mirrors at the protected site, in case

a failback is necessary). For installation and configuration information please see the EMC MirrorView

Adapter for VMware Site Recovery Manager Version 1.3 Release Notes.

VMware Site Recovery Manager for vSphere 4.0 is currently in beta and thus not generally available.
