Managing Volumes
A volume is a single accessible storage area with an allocated size. You can create volumes on your Iomega StorCenter px12-350r after creating Storage Pools.
Shares in Volumes
All Shares on the Iomega StorCenter px12-350r 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 Managing Shares. All iSCSI drives on the Iomega StorCenter px12-350r 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.
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.
3. Enter a size for the volume.
When you create a new volume, you can optionally enable encryption to protect your data if your Iomega StorCenter px12-350r 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 256-bit Advanced Encryption Standard (AES). To apply encryption to a volume, check Enable encryption. 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 Iomega StorCenter px12-350r is powered down. If any drives are removed while your system is powered down,
data on encrypted volumes will not be accessible. When the Iomega StorCenter px12-350r is rebooted, the system-generated passphrase is
automatically applied to encrypted volumes, unlocking the volumes and making data accessible.
Enter a passphrase — This is a more secure type of encryption and is the recommended option. Enter and verify a passphrase for the volume.
You can change the passphrase at any time. Whenever you restart the Iomega StorCenter px12-350r, an encrypted volume is unavailable until
you re-enter the passphrase.
After you create a passphrase, a new section for the volume appears called Volume Encryption.) When you want to unlock a volume, you 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 Iomega StorCenter px12-
350r. You should not save the backup master key to a drive that is connected to your Iomega StorCenter px12-350r. If a system failure
occurs, the passphrase stored on your Iomega StorCenter px12-350r may be lost, and your backup master key file is required to recover
and access your data. Also, if you forget your passphrase, you can reset it with the backed-up master key. Click Back up master key to
back up the master key file. To reset the passphrase, click Reset passphrase with master key and locate a previously saved master key
file. Enter a new passphrase and verify it.
4. Click Apply to save your changes.
