How Do I Enable (or Disable) PCI Controller
Clustering?
Under Windows NT 4.0, clustering allows redundancy among controllers. If
a controller fails, another controller can take over the disk drives and disk
arrays that were formerly handled by the failed controller. This mechanism
imparts a “ fault tolerance” among controllers.
❑ Select the Clustering Option.
☞ Use the arrow key to select Advanced Options on the main
menu, if necessary, then press Enter.
☞ From the Advanced Options menu, use the arrow key to
select Clustering, then press Enter.
(If clustering is not supported for the selected controller, a message appears
which reads: “ Clustering Not Supported by Firmware.” You will not be able
to use the clustering feature in this case.)
❑ Enable (or Disable) Clustering.
If clustering is currently disabled, the Clustering Control notice shown in
Figure 5-13 will be displayed:
