Managing Controllers
The RAID controllers are the heart of the VTrak subsystem. VTrak E-Class
models have one or two controllers. Management of Controllers includes the
following functions:
• Viewing the Controllers (page 99)
• Locating a Controller (page 99)
• Viewing Controller Information (page 100)
• Viewing Controller Statistics (page 101)
• Making Controller Settings (page 101)
• Clearing an Orphan Watermark (page 102)
Viewing the Controllers
To view information about the controllers:
1. Click the Subsystem icon in Tree View.
2. Click the Controllers icon.
The controller information appears under the Information tab in Management
View. Controller information includes:
• Controller ID (1 or 2)
• Alias, if assigned
• Model, if applicable
• Status – OK means normal
• Readiness Status – Active or Standby
• Locate – Click on the button to locate the controller. See below
VTrak subsystems with only one controller will always show that the second
controller is “Missing.”
If your VTrak subsystem has two controllers and one is “Missing,” see “Controller
Enters Maintenance Mode” on page 285 for more information.

2. Click the Controllers icon.
