Hints and tips.
Configuring the controller
By running ServeRAID Manager in Startable CD mode, you can configure the
controller before you install your operating system. The information in this section
assumes that you are running ServeRAID Manager in Startable CD mode.
To run ServeRAID Manager in Startable CD mode, turn on the server; then, insert
the CD into the DVD-ROM drive. If ServeRAID Manager detects an unconfigured
controller and ready drives, the Configuration wizard starts.
In the Configuration wizard, you can select express configuration or custom
configuration. Express configuration automatically configures the controller by
grouping the first two physical drives in the ServeRAID Manager tree into an array
and creating a RAID level-1 logical drive. If you select custom configuration, you
can select the two physical drives that you want to group into an array and create a
hot-spare drive.
Using express configuration
Complete the following steps to use express configuration:
1. In the ServeRAID Manager tree, click the controller.
2. Click Express configuration.
3. Click Next. The “Configuration summary” window opens.
4. Review the information in the “Configuration summary” window. To change the
configuration, click Modify arrays.
5. Click Apply; then, click Yes when asked if you want to apply the new
configuration. The configuration is saved in the controller and in the physical
drives.
6. Exit from ServeRAID Manager and remove the CD from the DVD-ROM drive.
7. Restart the server.
Using custom configuration
Complete the following steps to use custom configuration:
1. In the ServeRAID Manager tree, click the controller.
2. Click Custom configuration.
3. Click Next. The “Create arrays” window opens.
4. From the list of ready drives, select the two drives that you want to group into
the array.
5. Click the icon on the toolbar to add the selected drives to the array.
6. If you want to configure a hot-spare drive, complete the following steps:
a. Click the Spares tab.
b. Select the physical drive that you want to designate as the hot-spare drive,
and the icon on the toolbar to add the selected drives.
