Creating a logical volume

A "Logical Drive" is a set of drives grouped together to operate under a given RAID level and appears as a single contiguous drive. The VOYAGER 3000 is capable of grouping connected drives into 8 logical drives, each operating on the same or different RAID levels. The logical drive can be further divided into a maximum of 8 "Partitions" (using terminal commands). During operation, the host sees the logical drive or partition as one single drive. A total of 8 logical units is possible.

In this example we will show how to create a RAID level 5 set using a single tower configuration. The initial screen is shown in Figure 4-10.
