5. Click OK . Physical drives that are available for use are labeled Ready in the
tree. If the physical drive is not available for use (that is, it is owned by the other
server), the drive is labeled
Reserved in the tree.
Important
Hot-spare drives owned by the other server are not labeled Reserved . Be sure you do not
inadvertently use a hot-spare drive in both servers.
Adding logical drives to a cluster
Complete the following steps to add logical drives to a cluster:
1. Install the hard disk drives in the server or shared expansion enclosure. For
installation information, see the documentation that is included with the hard
disk drive and the server.
Important
Physical drives that are configured by one controller in the pair must appear as ready drives
to the other controller in the pair. Be sure to verify this status when you add drives
after the
servers are started. Before creating logical drives, restart both servers, or scan for new
drives using the ServeRAID Manager program on both servers, to make sure the added
physical drives appear as ready drives on both servers. For more information, see
“ServeRAID considerations” on page 108.
2. Using the ServeRAID Manager program, configure the physical drives for the
ServeRAID controller. For instructions, see Chapter 4, “Configuring ServeRAID
controllers” on page 35.
Note: If the drives will be shared, define only one logical drive per array.
3. In the ServeRAID Manager tree, click the controller for the cluster.
4. Click (
Configure for clustering
) on the toolbar. A window similar to the
following opens.
5. Click Shared or Non-shared for the logical drive you have just defined.
