Configuring the replacement servers

NAS Platform Series 5000 Hardware Reference

Part Number

Obtain the necessary IP addresses to be used for the replacement server. Servers shipped from the factory have not yet had the nas-preconfig script run on them, so a replacement server will not have any IP addresses pre-configured for your use.

IP addresses are required for the following:
  • Eth1 (cluster IP) – eth1
  • Eth1 (testhost private IP) – eth1
  • Eth0 (testhost external IP, which might vary) – eth0

For a single NAS server, when you run the nas-preconfig script, it reconfigures the server to the previous settings. This step allows the SMU to recognize the server as the same and to be managed.

The reconfigured settings are:
  • IP addresses for Ethernet ports 0 and 1
  • Gateway
  • Domain name
  • Host name

On the replacement server:

  1. Log in to the server.
  2. Run the nas-preconfig script.
    The IP addresses are assigned at this step.
  3. Reboot if you are instructed to by the script.
  4. Log in to the SMU using one of the IP addresses.
  5. Use a keyboard, video, and mouse (KVM) device or a serial cable to connect to the serial port. If you connect to the serial port, use the following SSH client settings:
    • 115,200 b/s
    • 8 data bits
    • 1 stop bit
    • No parity
    • No flow control
    • VT100 emulation
  6. Log in as root, and enter the ssc localhost command to access the command prompt.
  7. If using SAN attached, and/or host group security, update this to reflect the changes that are being made to the WWN, as described in Capturing information from the existing node.
  8. Add the new node as a managed server on the SMU.
  9. Enter evs list to see the IP configuration for the server.
  10. Using a supported browser, launch the NAS Manager using either one of the IP addresses acquired from the EVS list output.
  11. Click Yes to proceed past the security alert, and log in as admin.
  12. Verify and, if necessary, convert the new server to the model profile required.
    This step requires a separate process, training, and license keys. Contact Hitachi Vantara if the incorrect model arrives for replacement.
  13. Navigate to Home > Server Settings > Firmware Package Management to verify and, if necessary, upgrade the new server to the latest SU release.
  14. When replacing a server in a cluster only, navigate to Home > Server Settings > Cluster Wizard, and promote the node to the cluster.
    1. Enter the cluster name, cluster node IP address, subnet, and select a quorum device. Note that the node reboots several times during this process.
    2. When prompted, add the second node to the cluster.
    3. Enter the physical node IP address, log in as supervisor, and click finish. Wait for the system to reboot.
    4. Enter smu-uninstall to uninstall the embedded SMU.
  15. For all servers, navigate to Home > Server Settings > Configuration Backup & Restore, select the required backup file, and then click restore to restore the system from that backup file.
  16. When replacing a server in a cluster only, reconfigure the server to the previous settings:
    • IP addresses for Ethernet ports 0 and 1
    • Gateway
    • Domain name
    • Host name

    The SMU should recognize the node as the same and allow it to be managed.

  17. Navigate to Home > Server Settings > License Keys to load the license keys.
  18. Reboot the server.
  19. Reconnect the data cables to the server.
