# Configuring the ServeRAID controller for clustering

Notes: This action is not supported when using the following:

1. Integrated RAID controller
2. ServeRAID-5i controller
3. ServeRAID-6i/6i+ controller
4. ServeRAID-7k controller
5. ServeRAID-7t controller
6. ServeRAID-8i controller
7. HostRAID controller

Use this action to configure and view ServeRAID settings for clustering computers or using high-availability.

The ServeRAID Manager configures the controller name, partner controller name, and SCSI initiator IDs in bootable-CD mode only; otherwise, you can view only this information .

You can configure merge-group numbers for a logical drive that you have created during the current session of the ServeRAID Manager. If you have exited from the ServeRAID Manager since you created the logical drive, you cannot configure merge-group numbers for it. You must use the ServeRAID Manager in startable-CD mode to change merge-group numbers for logical drives that are not new.

1. In the Enterprise view, click (controller).
2. Right-click Clustering actions Configure for clustering.

3. Enter the controller name and partner controller name. You can specify a name up to 12 characters. When you enter the partner controller name, the merge-group information displays in the window.
   Note: Names are case sensitive.

4. Select the SCSI initiator IDs which can be 6 or 7.
   Note: The SCSI initiator IDs must be unique from the partner controller initiator IDs. The default is 7.

5. If you want a logical drive to merge to another controller if this controller fails, select the Shared box. Otherwise, if you do not want a logical drive to merge to another controller, select the Non-shared box.
   Notes:
     1. Non-shared is the default for all logical drives. The merge-group number is defined as [200 + the SCSI initiator ID]. You cannot change the merge-group number for a non-shared logical drive.
     2. If a logical drive is defined as shared, all physical drives in the logical drive must be on a shared channel.
6. Enter a merge-group number for the shared logical drive. This merge-group number must be unique from the partner controller (that is, the merge-group number for any logical drive belonging to the partner controller cannot be the same merge-group number).

   Note: The default merge-group number is the logical-drive number.
7. Once you have configured both controllers for clustering, you can click View shared drives to view the physical drives owned by a partner controller.
