If node4 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 Configure FC ports on node4 or Check and configure UTA/UTA2 ports on node4, or both sections.

Note

If node4 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 node2 disks to node4.

Make sure that node4 has sufficient rack space. If node4 is in a separate chassis from node2, you can put node4 in the same location as node3. If node2 and node4 are in the same chassis, then node4 is already in its appropriate rack location.

Configure FC ports on node4

If node4 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 as required, you might experience a disruption in service.

Before you begin

You must have the values of the FC port settings from node2 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 adapter, you configure them in Check and configure UTA/UTA2 ports on node4.

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

  1. Display information about all FC and converged network adapters on the system:

    system node hardware unified-connect show

  2. Compare the FC settings on node4 with the settings that you captured earlier from node1.

  3. Modify the FC ports on node4 as needed:

    • 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

      -t is the FC4 type: target or initiator.

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

  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. Take one of the following actions:

Check and configure UTA/UTA2 ports on node4

If node4 has onboard UTA/UTA2 ports or a UTA/UTA2A card, you must check the configuration of the ports and configure 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

UTA/UTA2 ports can be configured into native FC mode or UTA/UTA2A mode. FC mode supports FC initiator and FC target; UTA/UTA2 mode allows concurrent NIC and FCoE traffic to share the same 10GbE SFP+ interface and supports FC target.

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

UTA/UTA2 ports might be on an adapter or on the controller with the following configurations:

  • UTA/UTA2 cards ordered at the same time as the controller are configured before shipment to have the personality you requested.

  • 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 requested.

However, you should check the configuration of the UTA/UTA2 ports on node4 and change it, if necessary.

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

  1. Check how the ports are currently configured on node4:

    system node hardware unified-connect show

    The system displays output similar to the following example:

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

  2. 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.

  3. Verify the settings:

    ucadmin show

    Examine the output of the ucadmin show command and determine whether the UTA/UTA2 ports have the personality you want.

    The output in the following examples shows that the FC4 type of adapter "1b" is changing to initiator and that the mode of adapters "2a" and "2b" is changing to cna:

    *> ucadmin show
Node  Adapter  Current Mode  Current Type  Pending Mode  Pending Type  Admin Status
----  -------  ------------  ------------  ------------  ------------  ------------
f-a   1a       fc             initiator    -             -             online
f-a   1b       fc             target       -             initiator     online
f-a   2a       fc             target       cna           -             online
f-a   2b       fc             target       cna           -             online
4 entries were displayed.

  4. Take one of the following actions:

    If the CNA ports…​ Then…

    Do not have the personality that you want

    Go to Step 5.

    Have the personality that you want

    Skip Step 5 through Step 9 and go to Step 10.

  5. Take one of the following actions:

    If you are configuring…​ Then…

    Ports on a UTA/UTA2 card

    Go to Step 6

    Onboard UTA/UTA2 ports

    Skip Step 6 and go to Step 7.

  6. 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.

  7. 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 10GbE UTA.

    • -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.

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

    storage enable adapter <adapter_name>

  9. Cable the port.

  1. Exit Maintenance mode:

    halt

  2. Boot the node into boot menu:

    boot_ontap menu
