Adding and Managing Volumes

A volume is a single accessible storage area with an allocated size. You can create volumes after creating

Storage Pools.

Shares in Volumes

All Shares on the px12-450r Network Storage are added to volumes, and the size of the Share is limited by

the free space of the volume. When you create a Share, you can add it to a volume at the same time. This

is the simplest method for adding a Share to a volume. For more information on adding Shares to volumes,

refer to Using Share Volumes. All iSCSI drives on the px12-450r are added to volumes, and the size of the

iSCSI drive is limited by the free space of the volume. When you create an iSCSI drive, you can add it to a

volume at the same time. This is the simplest method for creating iSCSI drives. For more information on

adding iSCSI drives, refer to Managing iSCSI Drives.

To add a new volume:

1. On the Drive Management page, expand a Storage Pool, expand the Volumes section, and

click Add a Volume.

2. In the Information section, enter a name for the volume in the Volume field.

3. In the Size (GB) field, enter a size in gigabytes (GB) for the volume. Note that both the allocated

and available space for the volume displays.

4. When you create a new volume, you can optionally enable encryption to protect your data if your

px12-450r is lost or stolen. You can only enable encryption when you create a volume. Enabling

encryption can reduce performance since information transferred to and from the drives must be

processed using the 256-bit Advanced Encryption Standard (AES) protocol. To apply encryption

to a volume, click the Enable encryption checkbox. There are two options for encryption:

allowing the system to generate a passphrase, or creating one yourself. The passphrase is not a

256-bit encryption key.

● Generate and save passphrase on the system — Select this option to allow the system to

store a passphrase for the volume. This type of encryption works only when the px12-450r is

powered down. If any drives are removed while your system is powered down, data on the

encrypted volume will not be accessible. When the px12-450r is rebooted, the system-

generated passphrase is automatically applied to the encrypted volume, unlocking it and

enabling data access.

● Enter a passphrase — This is a more secure type of encryption and is the recommended

option. Click the Enter a passphrase option; then enter and verify a passphrase for the

volume. You can change the passphrase at any time. After restarting the px12-450r, an

encrypted volume is unavailable until you re-enter the passphrase. Note that the passphrase

must consist of eight or more characters.

After you create a passphrase, a new section for the volume appears called Volume Encryption.

When you want to unlock a volume, enter the passphrase in this section.

It is recommended that you save a backup of the master key file in a secure location, separate

from your px12-450r. You should not save the backup master key to a drive that is connected to

your px12-450r. If a system failure occurs, the passphrase stored on your px12-450r may be lost,

and your backup master key file is required to recover and access your data. Also, if you forget
