Set the fibre channel switch configuration settings for replication

All FC switches that are in the path from the source array to the destination array must be configured

to work in a CA EVA environment. For B-Series switches, access each switch by using Telnet, and

configure the switch as follows:

 switchdisable

 iodset (enables In Order Delivery)

 aptpolicy 1 (enables port-based routing)

 portCfgISLMode [slot/port] 1 (set for all MPX110 switch ports)

 portCfgGport [slot/port] 1 (set for all MPX110 switch ports)

 switchenable

Creating fabrics and zones

When implementing CA EVA with CLX EVA, follow the zoning guidelines described in the

Implementing Disaster Tolerance with Cluster Extension EVA section of this document.

Create data replication group(s)

A data replication group (DR group) is a CA EVA software connection between source virtual disks

and destination virtual disks. A DR group can contain virtual disks from multiple array disk groups,

but all DR group member virtual disks must be in the same array and must be set to use the same

preferred controller on the array.

HP Continuous Access EVA requires that all members (virtual disks) of a DR group be managed by the

same storage array controller. By default, one host port on the managing controller is used for

replication traffic.

HP recommends that all virtual disks used by a single application be in a single DR group. Only one

application per DR group is recommended. However, remember that applications, such as SQL

Server, can be implemented by using multiple application server instances.
