Virtual Disk
You can use this function to add iSCSI targets of other NAS or storage servers to the NAS as virtual
disks for storage capacity expansion. The NAS supports up to 8 virtual disks.
Supported file systems:
Format: Ext3, Ext4, FAT, NTFS, and HFS+.
Mount: Ext3, Ext4, FAT, NTFS, and HFS+.
Note:
The NAS supports a virtual disk with a maximum size of 16TB.
When a virtual disk (iSCSI target) is disconnected, the virtual disk will disappear from the
interface and the NAS will try to connect to the target in 2 minutes. If the target cannot be
connected to after 2 minutes, the status of the virtual disk will become "Disconnected".
Each virtual disk drive will be recognized as a single logical volume by the local system.
This function is only applicable to some models. To check for applicable models, please refer to
the product comparison table on the QNAP website.
To add a virtual disk to the NAS, follow the steps below:
1. Make sure an iSCSI target has been created. Go to "Storage Manager" > "Remote Disk" and click
"Add Virtual Disk".
2. Enter the target server IP and port number (default: 3260). Click "Get Remote Disk" and select a
target from the target list. If authentication is required, enter the username and the password.
Select the options "Data Digest" and/or "Header Digest" (optional). These are the parameters for
which the iSCSI initiator is verified when it attempts to connect to the iSCSI target. Then, click
"Next".
3. Enter a name for the virtual disk. If the target is mapped with multiple LUNs, select a LUN from
the list. Make sure that only this NAS can connect to the LUN. The NAS supports mounting EXT3,
EXT4, FAT32, NTFS, HFS+ file systems. If the file system of the LUN is "Unknown", select "Format
virtual disk now" and choose the file system. You can format the virtual disk as EXT3, EXT4, FAT
32, NTFS, or HFS+. By selecting "Format virtual disk now", the data on the LUN will be cleared.
Then, click "Next".
4. Click "Finish".
5. The storage capacity of the NAS is expanded by the virtual disk. Users can go to "Privilege
Settings" > "Share Folders" to create new shared folders on the virtual disk.
