Task 13: Setting-up High Availability

High Availability (HA) refers to establishing redundant paths between the VTrak
S3000 appliance (server) and the client. HA also builds fault tolerance and
scalability into the storage solution.
Use the PROMISE Management Console to set up your HA storage. There are
four steps.
1. Virtualize the Quorum.
2. Enable a configuration repository.
3. Configure network connections.
4. Set-up a Failover.
Before You Begin
Before you begin setting up high availability, be sure that you have a dedicated
LUN of at least 12 GB on VTrak subsystem. See "Configuring your Logical
Drives" on page 51.

1. In the Tree, under Physical Devices
right-click the dedicated LUN
menu.
The Disk Preparation dialog box opens
2. In the dialog box, choose Reserve for Virtual Device from the dropdown
menu and click the OK button.
The Warning (data loss) dialog box opens.
3. In the dialog box, type yes in the field provided and click the OK button.
