Attach Operation Fails

DescriptionThe operation to attach the controller to NAS cluster fails.
Workaround
  • Connect a keyboard and monitor to the controller that failed the attach operation, and view the error message to determine why the attach operation failed.
  • Verify the following:
    • While the controller was detached, the IP assigned to it on the client network was not allocated to another host. While the controller is detached, it loses its identity, including IP addresses. When it is attached, its identity is applied back to the controller, including the IP addresses.
    • Verify the default gateway is in the Primary subnet by using the NAS Manager. In Cluster Management > Network Configuration, view the default gateway. In Cluster Management > Subnets, to view the Primary subnet on the client network. If the default gateway is not in the Primary subnet, change the default gateway. For attach to succeed, the default gateway must be pingable.
  • After an attach operation fails, the controller must manually be reset to standby mode. This is done by connecting a keyboard and monitor to the controller that failed attach, and pressing the system identification button key System identification icon, as directed by the on-screen instructions.
