If node3 has onboard FC ports, onboard unified target adapter (UTA/UTA2) ports, or a UTA/UTA2 card, you must configure the settings before completing the rest of the procedure.

About this task

You might need to complete the section Configure FC ports on node3, the section Check and configure UTA/UTA2 ports on node3, or both sections.

Note NetApp marketing materials might use the term UTA2 to refer to converged network adapter (CNA) adapters and ports. However, the CLI uses the term CNA.

If node3 doesn't have onboard FC ports, onboard UTA/UTA2 ports, or a UTA/UTA2 card, and you are upgrading a system with storage disks, you can skip to Reassign node1 disks to node3.

Configure FC ports on node3

If node3 has FC ports, either onboard or on an add-on FC adapter, you must set port configurations on the node before you bring it into service because the ports are not preconfigured when the systems are shipped. If you don't configure the ports, you might experience a disruption in service.

Before you begin

You must have the values of the FC port settings from node1 that you saved in the section Prepare the nodes for upgrade.

About this task

You can skip this section if your system does not have FC configurations. If your system has onboard UTA/UTA2 ports or a UTA/UTA2 card, you configure them in Check and configure UTA/UTA2 ports on node3.

Important Enter the commands in this section at the Maintenance mode shell prompt.
Steps

  1. Compare the FC settings on node3 with the settings that you captured earlier from node1.

  2. Take one of the following actions to modify the FC ports on node3, as needed:

    In Maintenance mode (option 5 at boot menu):

    • To program as target ports:

      ucadmin modify -m fc -t target <adapter>

      For example: ucadmin modify -m fc -t target 2a

    • To program initiator ports:

      ucadmin modify -m fc -t initiator <adapter>

      For example: ucadmin modify -m fc -t initator 2b

  3. Verify the new settings by using the following command and examining the output:

    ucadmin show

  4. Halt the node:

    halt

  5. Boot the system from LOADER prompt:

    boot_ontap menu

  6. After you enter the command, wait until the system stops at the boot environment prompt.

  7. Select option 5 from the boot menu for maintenance mode.

  1. Perform one of the following actions:

Check and configure UTA/UTA2 ports on node3

If node3 has onboard UTA/UTA2 ports or a UTA/UTA2 card, you must check the configuration of the ports and possibly reconfigure them, depending on how you want to use the upgraded system.

Before you begin

You must have the correct SFP+ modules for the UTA/UTA2 ports.

About this task

If you want to use a Unified Target Adapter (UTA/UTA2) port for FC, you must first verify how the port is configured.

Note NetApp marketing materials might use the term UTA2 to refer to CNA adapters and ports. However, the CLI uses the term CNA.

You can use the ucadmin show command to view or verify the current port configuration, as shown in the following example output:

*> ucadmin show
         Current  Current    Pending   Pending      Admin
Adapter  Mode     Type       Mode      Type         Status
-------  -------  -------    --------  ----------   --------
0e      fc        target     -         initiator    offline
0f      fc        target     -         initiator    offline
0g      fc        target     -         initiator    offline
0h      fc        target     -         initiator    offline
1a      fc        target     -         -            online
1b      fc        target     -         -            online

UTA/UTA2 ports can be configured into native FC mode or UTA/UTA2 mode. FC mode supports FC initiator and FC target; UTA/UTA2 mode allows concurrent NIC and FCoE traffic sharing the same 10GbE SFP+ interface and supports FC targets.

You might find UTA/UTA2 ports on an add-on adapter or on the controller motherboard, and have the following configurations, but you should check the configuration of the UTA/UTA2 ports on the node3 and change it, if necessary:

  • UTA/UTA2 cards ordered when the controller is ordered are configured before shipment to have the personality you request.

  • UTA/UTA2 cards ordered separately from the controller are shipped with the default FC target personality.

  • Onboard UTA/UTA2 ports on new controllers are configured before shipment to have the personality you request.

    Warning You must be in Maintenance mode to configure UTA/UTA2 ports. Enter the commands in this section at the Maintenance mode shell prompt.
Steps

  1. If the current SFP+ module does not match the desired use, replace it with the correct SFP+ module.

    Contact your NetApp representative to obtain the correct SFP+ module.

  2. Verify the UTA/UTA2 port settings:

    ucadmin show

    Examine the output and determine whether the UTA/UTA2 ports have the personality you want.

    The output in the following example shows that the type of adapter "1b" is changing to initiator and that the mode of adapters "2a" and "2b" is changing to "cna". The CNA mode allows you to use the card as a network adapter.

    *> ucadmin show
         Current    Current     Pending  Pending     Admin
Adapter  Mode       Type        Mode     Type        Status
-------  --------   ----------  -------  --------    --------
1a       fc         initiator   -        -           online
1b       fc         target      -        initiator   online
2a       fc         target      cna      -           online
2b       fc         target      cna      -           online
*>

  3. Take one of the following actions:

    If the UTA/UTA2 ports…​ Then…

    Do not have the personality that you want

    Go to Step 4.

    Have the personality that you want

    Skip Step 4 through Step 8 and go to Step 9.

  4. Take one of the following actions:

    If you are configuring…​ Then…

    Ports on a UTA/UTA2 card

    Go to Step 5

    Onboard UTA/UTA2 ports

    Skip Step 5 and go to Step 6.

  5. If the adapter is in initiator mode, and if the UTA/UTA2 port is online, take the UTA/UTA2 port offline:

    storage disable adapter <adapter_name>

    Adapters in target mode are automatically offline in Maintenance mode.

  6. If the current configuration does not match the desired use, change the configuration as needed:

    ucadmin modify -m fc|cna -t initiator|target <adapter_name>

    • -m is the personality mode, fc or cna.

    • -t is the FC4 type, target or initiator.

      Note You must use FC initiator for tape drives and MetroCluster configurations. You must use the FC target for SAN clients.

  7. Place any target ports online by entering the following command once for each port:

    storage enable adapter <adapter_name>

  8. Cable the port.

  1. Exit maintenance mode:

    halt

  2. Boot the node into boot menu by running boot_ontap menu.
