You are asked to confirm your intention by typing DELETE VOLUME.
Adding a Volume
After deleting the volume, Add Volume tab displays listing the available configurable space on the
hard disks. All the disks are selected by default. You can elect to 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.
.
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.
