Clustering actions.
3. Click View shared drives. The View shared drives window opens.
4. Click Enable view shared drives.
5. Select the SCSI channel and SCSI ID of a physical drive on a shared channel.
6. Click OK. Physical drives that are available for use are labeled Ready in the
Main 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 Main 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
If you want to add logical drives to a cluster, do the following:
1. Install the hard disk drives in the server or shared expansion enclosure. For
installation information, refer to the documentation that is included with the hard
disk drive and the server.
Attention
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 96.
2. Using the ServeRAID Manager program, configure the physical drives for the
ServeRAID controller. Refer to “Chapter 4. Configuring ServeRAID controllers”
on page 27 for instructions.
Note: If the drives will be shared, define only one logical drive per array.
3. In the Main Tree, click the controller for the cluster.
4. Click (
Configure for clustering
) on the tool bar. A window similar to the
following opens.
