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.

If node4 does not 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 Map ports from node2 to node4.

Configure FC ports on node4

If node4 has FC ports, either onboard or on an FC adapter, you must set port configurations on the node before you bring it into service because the ports are not preconfigured. If the ports are not configured, 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 cluster 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 the new nodes with the settings that you captured earlier from the original node.

  3. Modify the FC ports on node4 as needed:

    • To program target ports:

      system node hardware unified-connect modify -type \| -t target -adapter port_name

    • To program initiator ports:

      system node unified-connect modify type \| -t initiator -adapter port_name

      -type is the FC4 type, target or initiator.

  4. Verify the new settings by entering the following command and examining the output:

    system node unified-connect show

  5. Take one of the following actions:

    If the default FC settings on the new nodes are…​ Then…

    The same as the ones you that captured on the original nodes

    Go to Step 9.

    Different from the ones that you captured on the original nodes

    Go to Step6.

  6. Exit Maintenance mode:

    halt

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

  8. Boot node4 by entering the following command at the boot environment prompt:

    boot_ontap

  9. 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 enables 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 can check the configuration of the UTA/UTA2 ports on node4 and change it, if necessary.

Warning Enter the commands in this section at the cluster prompt unless directed to enter Maintenance mode. If you have a MetroCluster FC system, you must be in Maintenance mode to configure UTA/UTA2 ports.
Steps

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

    system node hardware unified-connect show

  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. Examine the output of the system node hardware unified-connect show or ucadmin show command and determine whether the UTA/UTA2 ports have the personality you want.

  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 12 and go to Step 13.

  5. If the system has storage disks and is running Data ONTAP 8.3, boot node4 and enter maintenance mode:

    boot_ontap maint

  6. Verify the settings by entering the following command and examining its output:

    ucadmin show

  7. Take one of the following actions:

    If you are configuring…​ Then…​

    Ports on a UTA/UTA2A card

    Go to Step 8.

    Onboard UTA/UTA2 ports

    Skip Step 8 and go to Step 9.

  8. 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.

  9. If the current configuration does not match the desired use, enter the following command to 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 the FC target for SAN clients.

  10. If the system has storage disks, enter the following command:

    halt

    The system stops at the boot environment prompt.

    1. Enter the following command:

      boot_ontap

  11. If the system has storage disks, enter the following command:

    system node hardware unified-connect show

    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.

    cluster1::> system node hardware unified-connect show
               Current  Current   Pending  Pending    Admin
Node  Adapter  Mode     Type      Mode     Type       Status

f-a    2a      fc       target    cna      -          online
f-a    2b      fc       target    cna      -          online
4 entries were displayed.

  12. Place any target ports online by entering one of the following commands, once for each port:

    network fcp adapter modify -node node_name -adapter adapter_name -state up

  13. Cable the port.
