Networking and IO

  1. While performing any network operation, LC may go into an infinite loop if there are network glitches, leaks, or packet loss. Restart LC and retry the operation with the correct NFS share name details.
  2. If NPAR is enabled, LC might show unexpected behavior when configuring network settings. Disable NPAR and execute the network setting configurations. To disable the NPAR option, go to System Setup > Device Setting.
  3. When NPAR is enabled, the port numbers displayed on the LC Network Settings page (Settings > Network Settings) do not match the port numbers displayed on the Device Settings page (System Setup > Advanced Hardware Configuration > Device Settings).
  4. When Virtualization Mode is set to NPAR for network adapters that support the partitioning feature, PartitionState attribute can only be used for checking the state of partitions created for base partition in WSMan enumeration. You can see the states of all the partitions by pressing F2 during POST and going to Device Setting.
  5. The process of retrieving IPv6 address from the DHCP server with VLAN connection takes a few minutes. Wait for a few minutes and check the Network Settings page to view the assigned IPv6 address.
  6. Network operations such as Update, Export, or Import may take more time than expected. The delay may occur because the source or destination share is not reachable or does not exist, or due to other network issues.
  7. LC does not support SOCK4 proxy with credentials.
  8. LC UI supports share names and file paths that are up to 256 characters long. However, the protocol you use may only allow shorter values for these fields.
  9. Because of internal UEFI network stack protocol implementation, there may be a delay while opening the LC UI Network Settings page or while applying the network setting.
  10. Before performing any network operations, verify that the network is configured with the network cable connected. In some scenarios, a warning message may not be displayed but the operation may fail. Following are some examples that may lead to failure:
    • Static IP is configured without the network cable being connected.
    • Network cable is disconnected.
    • After a Repurpose and Retire operation is performed.
    • Network is configured with the network cable connected but the network card is replaced later.
  11. Any changes to the network settings in iDRAC take effect after 30 seconds. Any automation or user verification needs to wait for 30 seconds before verifying the new settings. iDRAC returns the old active value until the new values take effect. Any DHCP settings may take more time (>30 seconds) depending on the network environment.
  12. When trying to save network details using the Network Configuration page of LC UI, the following error message may be displayed: Unable to save the IPvX network settings, where X is the version of IP (IPv4 or IPv6). The following could be one reason for this error:

    On the Network Settings page of Lifecycle Controller GUI, the IP Address Source for both IPv4 and IPv6 is either DHCP or Static and DHCP is selected by default. So, even if you want to use only one version of IP address, LC tries to validate both versions, and displays an error if the network details for the unintended version cannot be validated.

    If the error does not apply to the IP version you are using, click OK to close the error message. All the other settings that you configured are saved. You can either click Cancel or Back to navigate away from the Network Settings page.

  13. If the Gateway IP is not configured in a network, the network settings and operations in LC UI may show some unexpected behavior.
