5 CREATING AN HA DEVICE This technical paper describes only creation of the first disk, since the procedure of creating the second one is alike. 1. Open a StarWind configuration file. Note: The default path is C:\Program Files\StarWind Software\StarWind\StarWind.cfg 2. Find the string "<!--<iscsidiscoverylistinterfaces value="1"/> -->" and uncomment it (should look as follows: <iscsidiscoverylistinterfaces value="1"/>). 3. Restart StarWind Service and repeat the same procedure on other StarWind HA nodes. 4. Launch StarWind Management Console: Start -> All Programs -> StarWind Software -> StarWind. Note: The StarWind Console icon appears in the system tray when the Console is running. To open StarWind Management Console, double-click the icon or right-click it and then select Start Management Console from the shortcut menu. 5. Select the server you want to provide with the iscsi target device from the Console tree. Doubleclick the host to connect. Note: If you are prompted to enter login and password, specify root and starwind, relatively. These are the default login and password, but you can always change them later. 6. After connecting to StarWind Service, you can create devices and targets on the server. Open Add Device Wizard by one of the following ways: Select Add Device from the Target menu. Select Add Device from the Devices shortcut menu (right-click to open it). 7. Add Device Wizard appears. Please, follow the wizard's steps to complete creation of a new HA device. 8. Select High Availability Device. 9. Click Next to continue. Page 5

Specify corresponding information in the Target Alias and Target Name text fields. Note: The name must be unique. Under this name the device is declared to the iscsi initiators connecting to the StarWind Service over an IP-network. 13. Click to specify the name and location of an HA virtual disk on the server. If you need to create new virtual disks, select the Create New checkbox. Page 6
