KERNSAFE - iSCSI SAN Software and Storage Virtualization

A VHDX device uses a Microsoft Virtual Hard Disk v2 file as the backing store for an iSCSI target. Like a standard image file target, it supports common disk-based workflows such as migration, backup, restore, and snapshot operations.

Creating VHDX Image File Device

Follow the steps below to create a .vhdx image device:

Step 1. Click New on the toolbar to open the Create iSCSI Target wizard.

Choose Hard Disk in the iSCSI Device Type group.

Press the Next button to continue.

Choose VHDX File from the iSCSI Device Type group.

Press the Next button to continue.

Step 2. Set the VHDX disk parameters.

In the VHDX Disk Configuration window, you can either open an existing image file or create a new one. To create a new VHDX file, select the file location and specify the capacity.

There are two options to choose from:

• Dynamically expanding: Expands the file as data is written to save storage space.
• Fixed size: Creates the full-size file immediately and allocates all required disk space in advance.

Then press the Next button to continue.

Step 3. Finish creating the iSCSI target.

Enter the target name.

Select an authorization mode. If you need more information, see Authorization Mechanism.

Global Authorization: The target inherits CHAP and IP filter settings from the global configuration. If this option is cleared, the target uses its own authorization settings.

Concurrent Access: Allows multiple initiators to access the target concurrently when the workload supports shared access.

Report Readonly: Reports the target as read-only when the initiator does not have write permission.

Click Finish to complete target creation.
