Procedures for adding attached disk backup storage

Use these procedures to add attached disk storage to the Unitrends Backup appliance. You can view the appliance's disk storage in the Edit Storage dialog. Disks that have been added to the Unitrends Backup VM by using the hypervisor display as /dev/sdx/, where x indicates alphabetically the order in which the disks were added to the VM. For example, the initial disk is always /dev/sda/, the first disk that was added as the initial backup storage device is /dev/sdb/, the next would be /dev/sdc/, etc.

See the following topics for details:

To view or edit attached disk backup storage

1

On the Configure > Appliances page, select your appliance.

2

Click the Storage tab.

3

Select the Internal storage and click Edit.

4

5

Once finished editing the storage, click Save.

To add a disk and expand the storage device

Note:  Once a disk has been added, it cannot be removed.

1

Go to the hypervisor and add a virtual disk to the Unitrends Backup VM.

For an appliance whose initial backup storage is DAS internal to an ESXi host, see one of the following VMware documents:

–

vSphere 5.1: Create a Virtual Disk in vSphere Client 5.1

–

vSphere 5.5: Create a Virtual Disk in vSphere Client 5.5

–

vSphere 6.0: Create a Virtual Disk in vSphere Client 6.0

–

vSphere 6.5: Add a Hard Disk to a Virtual Machine

•

For an appliance whose initial backup storage is DAS internal to a Hyper-V host, Unitrends recommends that you use a VHD(X) disk and that you add the disk to the SCSI controller. See the following Microsoft documents:

–

To create a virtual hard disk

–

To add a hard disk to a virtual machine

•

For an appliance whose initial backup storage is DAS internal to an AHV host, edit the appliance VM to add a vDisk to the ISCSI controller (by selecting ISCSI in the Bus Type list). For details, see Managing a VM (AHV) in the Prism Web Console Guide.

•

For an appliance whose initial backup storage is DAS internal to a XenServer host, Unitrends recommends that you add the VHD disk to the SCSI controller. VM disks cannot be attached as Read Only. Be sure to use the Read Only = No setting when attaching disks.

•

For an appliance whose initial backup storage is on an external SAN connected to the hypervisor, add another LUN and expose it to the Unitrends Backup VM. Then go to the hypervisor and add new virtual disks to the VM using storage on the LUN you added.

•

For an appliance whose initial backup storage is on an external NAS share connected to the hypervisor, add another NAS share. Then go to the hypervisor and add new virtual disks to the Unitrends Backup VM using storage on the share you added.

2

On the Configure > Appliances page, select your appliance.

3

Click the Storage tab.

4

Select the Internal storage and click Edit.

5

In the Manage Attached Disks area:

•

To add an attached disk, select a disk from the list of available attached disks and click Add.

•

To remove a disk, select it in the list and click Remove.

•

Click Reset to revert all disk settings to the original settings.

•

Click Refresh to refresh the list of available disks.

6

(Optional) Adjust the storage allocation for Backups versus Instant Recovery.

7

Click Save.

On the Configure > Appliances page, the status initially displays as Pending. When the storage has expanded to include the new disk, its status changes to Online and the storage can be used.

8

(Optional) repeat this procedure to add another disk.
