Finalizing and verifying the replacement server configuration

NAS Platform and Unified Storage Series 4000 Hardware Reference

Part Number
The Fibre Channel (FC) link speed varies according to the server model. Use the appropriate speed for your model.
Model Fibre Channel link speed
HNAS 4040 4 Gbps
HNAS 4060, 4080, and 4100 8 Gbps

On the replacement server:

Note: The following steps show the FC link speed as 8 Gbps as an example.
  1. Navigate to Home > Server Settings > License Keys to load the license keys.
  2. Remove the previous license keys in the backup file, and add the new keys.
  3. Use fc-link-speed to verify and, if necessary, configure the FC port speed as required.; for example:
    Note: The examples shows the link speed setting for models HNAS 4060, 4080, and 4100 .
    1. Enter fc-link-speed to display the current settings.
      host:$ fc-link-speed
      FC 1:     8 Gbps
      FC 2:     8 Gbps
      FC 3:     8 Gbps
      FC 4:     8 Gbps
    2. Enter fc-link-speed -i port_number -s speed for each port.
      host:$ fc-link-speed -i 1 -s 8
      Set interface 1 link speed OK
      FC 1:     8 Gbps
      host:$ fc-link-speed -i 2 -s 8
      Set interface 2 link speed OK
      FC 2:     8 Gbps
      host:$ fc-link-speed -i 3 -s 8
      Set interface 3 link speed OK
      FC 3:     8 Gbps
      host:$ fc-link-speed -i 4 -s 8
      Set interface 4 link speed OK
      FC 4:     8 Gbps
    3. Enter fc-link-speed to verify the settings.
      host:$ fc-link-speed
      FC 1:     8 Gbps
      FC 2:     8 Gbps
      FC 3:     8 Gbps
      FC 4:     8 Gbps
  4. Use the fc-link-type command to configure the server in fabric (N) or loop (NL) mode.
  5. Modify zoning and switches with the new WWPN, if you are using WWN-based zoning.
    If you are using port-based zoning, the no modifications are necessary for the switches configurations.
  6. Open Storage Navigator and reconfigure LUN mapping and host group on the storage system that is dedicated to the server with the new WWPNs. Perform this step for every affected server port.
  7. If the server does not recognize the system drives, enter fc-link-reset to reset the fiber paths.
  8. Enter sdpath to display the path to the devices (system drives) and which hport and storage port are used.
  9. Enter sd-list to verify the system drives statuses as OK and access is allowed.
  10. Enter span-list to verify the storage pools (spans) are accessible.
    Note: In this instance, cluster is synonymous with the standalone server.
  11. Enter span-list-cluster-uuids span_label to display the cluster serial number (UUID) to which the storage pool belongs.
    The UUID is written into the storage pool’s configuration on disk (COD). The COD is a data structure stored in every SD, which provides information how the different SDs are combined into different stripesets and storage pools.
  12. Enter span-assign-to-cluster span_label to assign all the spans to the new server.
  13. Verify the IP routes, and enable all the EVSs for file services in case they are disabled.
  14. Reconfigure any required tape backup application security.
  15. Navigate to Home > Status & Monitoring > Event Logs, and click Clear Event Logs.
  16. Navigate to Home > Status & Monitoring > System Monitor and verify the server status:
    • If the server is operating normally, and is not displaying any alarm conditions, run a backup to capture the revised configuration, and then download another diagnostic to support. Permanent license keys for the replacement server are normally provided within 7 days.
    • If the server is not operating normally for any reason, contact support for assistance.
  17. Confirm all final settings, IP addresses, customer contact information, service restarts, client access, and that customer expectations are all in place. Features such as replication and data migration should all be confirmed as working, and all file systems and storage pools should be online.
