How do I create a volume and select the RAID level on my ReadyDATA storage system?

To create a volume and select the RAID level:

1. Select System > Storage.

The Storage screen displays.

The following figure shows one optional expansion disk array and one volume. A new system does not have any volumes.

2. In the enclosure, click the disks that you want to select as members of the volume.

You can select disks with a black color coding only. If you have an expansion disk array, you can select disks from both the ReadyDATA and the expansion disk array.

The selected disks are highlighted and all volume buttons become available, including the New Volume button under the enclosure:

3. Below the enclosure, click New Volume.

The New Volume pop-up screen displays:

The RAID levels that are displayed depend on the number of disks that you selected.

4. Configure the following settings:

  • Name. Enter a name for the volume. The volume name must begin with a letter, and can contain only alphanumeric characters, underscores (_), hyphens (-), periods (.), and colons (:). The volume names mirror, logs, and spare are reserved and cannot be used, as are all names that begin with the c[0-9] pattern. However, you can use names that begin with the C[a-z0-9] or c[a-z] pattern.
  • RAID. From the drop-down list, select the RAID level. The RAID level that you can select depends on the number of disks that you selected in Step 2. For more information on RAID levels, see the "What is RAID and how does it work with my ReadyDATA storage system?" support article.

5. Click Create.

The volume is created.

6. To the left of the enclosure, click the new volume and note the following:

  • The color of the selected disks in the enclosure turns blue (1).
  • The name of the new volume displays above the enclosure (2).
  • The selected RAID level for the new volume displays below the enclosure (3).
  • Information about the new volume displays to the left of the enclosure (4).
  • The virtual LED indicates the health status of the volume (5).

Information about the volume displays to the left of the enclosure, and is explained in the following table. The color coding refers to the colors in the volume icon (that is, the circle) and the information that is displayed to the right of it. The volume icons are black in the previous figure but can display colored slices).

Description

Color Coding

Information to the right of the volume icon

Data

The volume storage space that is consumed by data in MB, GB, or TB.

Purple

Snapshots

The number of snapshots that have been taken.

Green

Reserved

The volume storage space that is reserved in MB, GB, or TB.

Orange

Free

The volume storage space that is available in MB, GB, or TB.

Black or gray

Type

The configured RAID level.

Not applicable

Dedupe

By default, dedupe is 1.00, indicating that deduplication is enabled and that the initial deduplication ratio is set. A number higher than 1.00 indicates that data has been deduplicated and that the deduplication ratio has increased. The deduplication ratio is the data capacity of the volume divided by its usable storage capacity.

 


Note: You cannot disable deduplication on a volume, but you can do so on a share or LUN that resides on the volume.

Not applicable

Compression

By default, compression is 0.00, indicating that compression is enabled but that data has not yet been compressed. A number higher than 0.00 indicates the number of times that data has been compressed. For example, 5.00 indicates that data has been compressed five times.

Not applicable

Virtual health LED to the left of the volume icon

Green

The volume is healthy.

Yellow

The volume is degraded.

 


Note: Even though the health LED might be yellow and not red, the volume might actually be bad or faulty if the number in the Free field (to the right of the volume icon) is a strange or negative number and if the numbers in the Data, Snapshots, and Reserved fields (also to the right of the volume icon) are zero.

Red

The volume is bad or faulty.
