To create additional backup storage for Hyper-V

Use this procedure to add backup storage from the Hyper-V hypervisor. If you have deployed UEB to an external NAS or SAN, add storage (through the hypervisor) that resides on that external array. If you have deployed to a disk that is internal to the hypervisor, add direct attached storage (DAS).

Warning: It is strongly recommended that all UEB storage is either DAS (internal to the hypervisor) or resides on one external NAS or SAN storage array. If you configure storage across multiple storage arrays and one becomes unavailable, all backup data is corrupted, resulting in total data loss.

1        Launch Hyper-V Manager, right-click the Unitrends VM, and select Shut Down.

The VM shuts down and its State changes to Off.

2        Right-click the Unitrends VM and select Settings.

3        On the Hardware tab, select VMBus SCSI Controller. In Hyper-V Manager 2012 and higher, select SCSI Controller.

Note: IDE disks are not supported. You must use SCSI for storage expansion.

4        In the SCSI Controller area, select Hard Drive and click Add.

5        In the Hard Drive area, review the Controller and Location information, enter a full pathname for the new .vhd file, then click New.

6        On the Choose Disk Type screen, select a disk type and click Next to continue.

You can choose any type, but for best performance, select Fixed Size.

7        Specify a Name and Location for the .vhd file, and click Next.

8        Select Create a new blank virtual hard disk. Select VHD or VHDX and specify a Size in GB.

Note: VHDX disks are available in Hyper-V 2012 and higher.

9        Click Next. Review the configuration settings and click Finish to add the disk.

You see the message Creating the new virtual hard disk.

10    Once the disk is created, it displays in the hardware area under VMBus SCSI Controller. Click OK to exit.

11    Power on the VM, then proceed to To expand storage to add the disk to the Unitrend system’s backup storage device.

Note: The system can detect up to 64 Hyper-V disks without a reboot. If you are adding more than 64 disks, a reboot may be required.
