Adding a disk
To replace the mirror disk, see “Replacing the mirror disk.”
To add a disk used for the mirror disk, follow the steps below:
1. Make sure that the cluster is working properly.
2. If the group is running on the server to which a disk is added, move the group.
3. Shut down only one server by using the WebManager, and power it off.
4. Expand the disk, and start the server.
5. Return the server to the cluster, and rebuild the mirror again.
6. Configure the settings for the disk by the server on which the disk is added.
• Reserve a data partition and a cluster partition for mirror disk using Disk Management
(On the Start menu, point to Settings, and click Control Panel. Double-click
Administrative Tools and then Computer Management, and click Disk
Management.). Set their drive letters so that they will be the same on both of the
servers.
7. Perform the steps 2 to 6 on other server.
8. Suspend the cluster by using the WebManager.
9. Start the Builder, and right-click the group to which the mirror disk resource is added, and
add the mirror disk resource from Add Resource.
10. Select Upload the Configuration File from the File menu of the Builder, and reflect the
cluster configuration data to the cluster.
11. Resume the cluster by using the WebManager.
12. Start the added mirror disk resource or the group that added the mirror disk resource. If Auto
Mirror Initial Construction is set to be performed in Cluster Properties, the initial mirror
construction is started. If Auto Mirror Initial Construction is set not to be performed,
perform the initial mirror construction manually.
13. Move group as necessary.
