You can install and configure InfoScale Storage and Exchange Server in a Microsoft cluster for high availability on a single site.

Note:

For Exchange 2007, you can only cluster the Mailbox server role. Refer to the Microsoft documentation for other Exchange requirements.

Table: Process for deploying Exchange Server with InfoScale Storage in a Microsoft high-availability cluster

Action

Description

Understand the configuration

See Planning your Exchange Server high availability configuration.

Configure the storage hardware and network

Set up the storage hardware for a cluster environment.
Verify the DNS entries for the systems on which Exchange will be installed.

See Configuring the storage hardware and network.

Establish a Microsoft cluster

Establish the cluster before installing InfoScale Storage.

For details, refer to the Microsoft documentation.

Install InfoScale Storage with the Microsoft Failover Cluster option

For more information, see the Veritas InfoScale Installation and Upgrade Guide.

Configure and manage disk groups and volumes

Use the VEA console to create disk groups and volumes for the application and for the quorum resource.

See Tasks for configuring InfoScale Storage.

Note:

Setting up a Microsoft failover cluster creates physical disk resources for all the basic disks on the shared bus. To use these disks when you create your SFW cluster disk groups, you must first remove the physical disk resources from the cluster. Otherwise, a reservation conflict occurs.

Implement a dynamic mirrored quorum resource

Create a dynamic cluster disk group with a mirrored volume for the quorum disks.
Create a Volume Manager Disk Group (VMDG) resource for the quorum disk group.
Change the cluster quorum resource to the dynamic mirrored quorum resource.

See Tasks for implementing a dynamic mirrored quorum resource.

Add the VMDG Resource for the First Storage group to the quorum group

Add the VMDG disk group resource(s) for the First Storage Group to the quorum group.

See Adding a Volume Manager Disk Group resource for Exchange 2007 installation.

Install Exchange Server

See Installing Exchange Server.

Add the VMDG resources to the Exchange group

See Adding the Volume Manager Disk Group resources to the Exchange group.

Set the database dependency on the disk group resource

See Setting the database dependency on the disk group resource.

Move Exchange databases and logs to shared storage.

See Moving Exchange databases and logs to shared storage.

Verify the cluster configuration

Move the online Exchange Server cluster group to the second node and back to the first node.

See Verifying the Exchange Server group in the Microsoft cluster.
