9.4.2 Creating an Integrated Mirroring Volume
An Integrated Mirroring (IM) volume (also called RAID 1) duplicates all
data from one drive to a second drive. Integrated Mirroring provides
complete data redundancy, but at the cost of doubling the required data
storage capacity. You can optionally add a hot spare disk to provide even
more data security. Follow these steps to create an IM volume on an
adapter that does not currently have a configured volume.
1. On the Adapter List menu, highlight an adapter and press Enter. The
Adapter Properties menu appears.
2. Highlight RAID Properties and press Enter. The Select New Array
Type screen appears.
