Adding and Editing Logical Volumes

Adding and Editing Logical Volumes

To add or edit a logical volume

In the Configuration tab's navigation pane, click Storage > Volumes.
The Storage > Volumes page appears.
Do one of the following:
- To add a new volume, click New.
- To edit an existing volume, click on its name.
The Logical Volume Wizard opens, displaying the Specify Volume Details dialog box.
Complete the fields using the information in the following table.

Click Next.

The following things happen:

If you are adding a new volume or editing an encrypted volume, the Volume Encryption dialog box appears.
1. To encrypt the contents of this volume, select the Make this volume encrypted check box.
  This check box is disabled when editing a volume.

	Tip
	Volume encryption is supported both for standalone volumes and volumes residing in RAID arrays.
	Tip
	The encryption method employed is the Advanced Encryption Standard (AES-256 CBC ESSIV). Enabling volume encryption may reduce performance.

In the Passphrase and Re-type passphrase fields, type the passphrase you want to use for accessing the volume.
The Passphrase Strength field displays the passphrase's strength.

	Warning
	It is important to keep this passphrase in a safe place, as there is no way of retrieving it if you lose it. If you reset your appliance to its default settings, you cannot access the volume without this passphrase.

Click Next.

The Name this Logical Volume dialog box appears.

In the Volume Name field, type a name for the volume.
Click Next.
The Wizard Completed screen appears.
Click Finish.

In this field...	Do this...
Storage Device	Select the array on which you want to create the volume. The size of each array is listed next to its name. You can also create volumes directly on an empty drive. This is called a standalone drive.
Volume Size	Do one of the following: Use the slide to indicate the desired size of the volume out of the total array size. Type the desired volume size in GB in the field provided. Note: If snapshots are enabled, you cannot decrease the size of the volume.
Volume Type	Select the desired volume type: File System (NAS). A NAS volume, which can be accessed using the various file sharing protocols supported by the appliance. Raw volume (SAN). A SAN volume, which can be accessed using iSCSI only. For more information on volume types, see Overview. Once set, the volume type cannot be changed.
Support snapshots	Select this option to enable NEXT3 snapshots for the volume. The volume will be installed with the NEXT3 file system, and snapshots will automatically be taken of the volume before each cloud backup or outgoing synchronization rule is performed. Note: This option relates to NEXT3 snapshots only, and clearing it will not prevent cloud snapshots from being created. For information on types of snapshots, see Working with Snapshots. This option is only available if the volume type is File System (NAS).
Support quotas	Select this option limit the amount of storage space allocated to each volume user. Each user can then be allocated a specific storage space quota, as described in Allocating Disk Quotas to Users. If quotas are not enabled, then each user will be able to use unlimited amount of space on this volume.
Default Quota	To set a default storage space quota for volume users, select this option and then type the desired default quota in MB in the field. This quota will be allocated to each user by default. If this option is not enabled, then an unlimited amount of space will be allocated to each user by default. In either case, the default allocated quota can be overridden, as described in Allocating Disk Quotas to Users.
