Restoring system defaults and configuring the HBA type on a previously used controller module

If your controller modules have been used previously, you must reset them for a successful MetroCluster configuration.

1. At the LOADER prompt, return the environmental variables to their default setting: set-defaults
2. Boot the node into Maintenance mode, and then configure the settings for any HBAs in the system:
   1. Boot into Maintenance mode: boot_ontap maint
   2. Check the current settings of the ports: ucadmin show
   3. Update the port settings as needed.

   If you have this type of HBA and desired mode...	Use this command...
   CNA FC	ucadmin modify -m fc -t initiator adapter_name
   CNA Ethernet	ucadmin modify -mode cna adapter_name
   FC target	fcadmin config -t target adapter_name
   FC initiator	fcadmin config -t initiator adapter_name

3. Exit Maintenance mode: halt
   After you run the command, wait until the node stops at the LOADER prompt.
4. Boot the node back into Maintenance mode to enable the configuration changes to take effect: boot_ontap maint
5. Verify the changes you made:

   If you have this type of HBA...	Use this command...
   CNA	ucadmin show
   FC	fcadmin show

6. Exit Maintenance mode: halt
   After you run the command, wait until the node stops at the LOADER prompt.
7. Boot the node to the boot menu: boot_ontap menu

   After you run the command, wait until the boot menu is shown.
8. Clear the node configuration by typing wipeconfig at the boot menu prompt, and then press Enter.

   The following screen shows the boot menu prompt:
