installed on VMware Site Recovery Manager (SRM) servers and enables communications between SRM and HP StorageWorks Command View EVA (and HP StorageWorks Continuous Access EVA for remote replication). HP EVA Virtualization Adapter performs the following functions: • Discovers disk arrays • Discovers - HP EVA4000/6000/8000 | HP StorageWorks EVA Virtualization Adapter administrator - Page 8
is: 1. SRM makes a request to HP EVA Virtualization Adapter for replicated LUNs on a local (protected) array. 2. HP EVA Virtualization Adapter connects to HP Command View EVA servers and requests replicated vdisks on the protected array. 3. HP Command View EVA looks for vdisks that are members of - HP EVA4000/6000/8000 | HP StorageWorks EVA Virtualization Adapter administrator - Page 9
the recovery plan, it provides the LUN information needed for failover to HP EVA Virtualization Adapter. The information includes: • Recovery site storage array ID • Vdisk name • Recovery ESX server HBA ports (WWNs) for post-failover LUN presentation EVA Virtualization Adapter administrator guide 9 - HP EVA4000/6000/8000 | HP StorageWorks EVA Virtualization Adapter administrator - Page 10
hosts. NOTE: For failover testing, LUN number assignment is the LUN number used by the snapshot and not the parent vdisk. Communication path HP EVA Virtualization Adapter provides communications between HP StorageWorks Command View EVA and SRM. A detailed view of the architecture is shown in Figure - HP EVA4000/6000/8000 | HP StorageWorks EVA Virtualization Adapter administrator - Page 11
the recovery array. • Split active Command View EVA server In this configuration, each Command View EVA management server actively manages a single array (the local array). Each Command View EVA management server manages the remote array passively.

Then enter the address and login credentials used for HP Command View EVA and - HP EVA4000/6000/8000 | HP StorageWorks EVA Virtualization Adapter administrator - Page 17
4. Select the HP EVA disk array name that is connected to protected ESX servers. NOTE: You will also need to configure the recovery site array manager using this procedure.

NOTE: After removing HP EVA Virtualization Adapter, restart SRM service so it can be reflect that EVA Virtualization Adapter is no longer available. 24 Installing and removing HP EVA Virtualization - HP EVA4000/6000/8000 | HP StorageWorks EVA Virtualization Adapter administrator - Page 25
. This could be the case if some of the hardware at the protected site was not replaced after a disaster and you will be employing the existing hardware. If new hardware has been installed, it is not necessary to delete existing protection groups.
