Verification

After all upper steps are done, the iSCSI has already been mounted in WIndows. We can check this with "Disk Management".

But before use, the disk needs to be initialized and format as the usable volume. Please follow the steps below:

Right-click > select Initialize Disk > choose GPT > OK
Right-click > select "new simple volume" to create a volume. Wait until the volume creation is finished.

Then the disk will be a local disk and users can save any files in the volume.
