Adding a Volume
After deleting the volume, the Add Volume tab lists the available configurable space on the hard
disks. All the disks are selected by default. You can specify a hot spare disk if you wish. A hot
spare remains in standby mode and automatically regenerates the data from a failed disk from the
volume. A hot spare disk is available for RAID level 1 and RAID level 5 only if there are enough
disks to fulfill the required minimum plus one.

Figure 2-17
To add a volume:
1. Select the hard disks. In this example, we select the first three disks and elect not to specify
any of them as a hot spare.
2. Select the RAID level. RAID level determines how the redundancy, capacity utilization, and
performance are implemented for the volume. Typically in a configuration of three or more
disks, RAID level 5 is recommended.
In our example, we selected RAID level 5 for the three selected disks.
