To enable DMP

1. With SFW on the first server, bring up DMP and include the disks on the storage array and optionally the two direct-attached storage devices. To include each storage array or direct-attached storage device under DMP control:

   • Display the Array Settings screen for the device you are including by doing the following:

     • In the tree view under the Disks icon, select a disk from the storage array.

     • In the right pane, click the Paths tab for the disk. Only one path should display in the Paths tab, since the disk is not yet under DMP control.

     • Right-click the path and select Array Settings from the path context menu that comes up.

     • The Array Settings window comes up. The Exclude checkbox is checked.

   • Uncheck the Exclude checkbox.

2. Using appropriate cables, connect the second path on Server A to Switch 2.

   • Connect the path through Server A, HBA 2, Channel 2 of the direct-attached storage, and Controller 2 of the large storage array.

   • Complete any necessary configuration of the switch.

3. Go to Actions and select Rescan to verify that two paths are shown under the Paths tab. This indicates that one set of disks has two paths and that DMP DSMs is installed correctly.
4. Complete step 1 to step 3 on Server B.

   Microsoft clustering and DMP are now set up, and the upgraded configuration steps are complete.
