Moving a VJBOD Disk to Another QNAP NAS

  1. Note the details of the VJBOD disk's remote LUN.
    1. Go to Storage & Snapshots > Storage > Disks/VJBOD.
    2. Click VJBOD/VJBOD Cloud, and then select VJBOD Overview.

      The VJBOD Overview window opens.

    3. Locate the VJBOD disk that you want to move, and then note the Remote LUN Name and the IP address under Remote NAS.
  2. Detach the VJBOD disk's static volume or storage pool.
    1. Go to Storage & Snapshots > Storage > Storage/Snapshots.
    2. Select the static volume or storage pool on the VJBOD disk.
    3. Click Manage.

      The Volume Management or Storage Pool Management window opens.

    4. Click Action, and then select Safely Detach.
  3. Remove the VJBOD disk from the NAS.
    1. Go to Storage & Snapshots > Storage > Disks/VJBOD.
    2. Select the VJBOD disk.
    3. Click Action, and then select Disconnect.

      The status of the VJBOD disk changes to Disconnected.

    4. Click Action, and then select Delete.

      QTS removes the VJBOD disk from the local NAS.

  4. Add the VJBOD disk on another QNAP NAS.
    1. On the other NAS, go to Storage & Snapshots > Storage > Disks/VJBOD.
    2. Click Create, and then select Create Virtual JBOD.

      The Create Virtual JBOD Disk Wizard opens.

    3. Click Next.
    4. Specify the IP address or hostname of the remote NAS.
    5. Specify an administrator account and password of the remote NAS.
      Important:

      For security reasons, QNAP does not recommend using the "admin" account.

    6. Optional: Specify the system administration port of the remote NAS.
      Tip:

      The default port is 8080. If HTTPS is enabled, the default port is 443.

    7. Click Next.
    8. Optional: Select the local interface that will be used by VJBOD.
    9. Optional: Select the remote interface that will be used by VJBOD.
    10. Optional: Select Use iSER when available.

      Enabling iSER increases data transfer speeds and reduces CPU and memory load.

    11. Click Next.
    12. Select Choose an existing iSCSI LUN on the selected NAS.
    13. Click Next.
    14. Select the LUN containing the VJBOD disk.
    15. Click Next.
    16. Optional: Enable CRC checksums.

      Initiators and targets communicate over TCP connections using iSCSI protocol data units (PDU). The sending device can send a checksum with each PDU. The receiving device uses this checksum to verify the integrity of the PDU, which is useful in unreliable network environments. There are two checksum types, which can be enabled separately.

      Checksum Type

      Description

      Data Digest

      The checksum can be used to verify the data portion of the PDU.

      Header Digest

      The checksum can be used to verify the header portion of the PDU.

    17. Click Next.
    18. Review the summary, and then click Next.

      QTS creates a VJBOD disk using the LUN. The disk appears at Storage & Snapshots > Storage > Disks/VJBOD.

    19. In the actions list, select Recover Existing Data.
    20. Click Finish.

QTS scans for and restores any storage pools, volumes, and LUNs on the VJBOD disk.
