Cluster and storage switches

Install the Reference Configuration File (RCF)

Contributors netapp-jolieg

You can install the RCF after setting up the Nexus 92300YC switch for the first time.

Switch and node nomenclature

The examples in this procedure use the following switch and node nomenclature:

  • The names of the two Cisco switches are cs1 and cs2.

  • The node names are node1 and node2.

  • The cluster LIF names are node1_clus1 and node1_clus2 for node1 and node2_clus1 and node2_clus2 for node2.

  • The cluster1::*> prompt indicates the name of the cluster.

  • The cluster ports on each node are named e0a and e0b.

    See the Hardware Universe^ for the actual cluster ports supported on your platform.

Supported ports and node connections

  • The Inter-Switch Links (ISLs) supported for the Nexus 92300YC switches are ports 1/65 and 1/66.

  • The node connections supported for the Nexus 92300YC switches are ports 1/1 through 1/66.

  • The examples in this procedure use two nodes. These nodes use two 10GbE cluster interconnect ports e0a and e0b. See the Hardware Universe to verify the correct cluster ports on your platforms.

Before you begin

  • You must have the current RCF.

  • The cluster must be fully functioning (there should be no errors in the logs or similar issues).

  • You must have checked or set your desired boot configuration in the RCF to reflect the desired boot images if you are installing only NX-OS and keeping your current RCF version.

  • If you need to change the boot configuration to reflect the current boot images, you must do so before reapplying the RCF so that the correct version is instantiated on future reboots.

  • You must have consulted the switch compatibility table on the Cisco Ethernet switch page for the supported ONTAP, NX-OS, and RCF versions.

  • There can be command dependencies between the command syntax in the RCF and that found in versions of NX-OS.

About this task

The procedure requires the use of both ONTAP commands and Cisco Nexus 9000 Series Switches commands; ONTAP commands are used unless otherwise indicated.

The command outputs might vary depending on different releases of ONTAP.

Steps

  1. Connect the cluster switch to the management network.

  2. Use the ping command to verify connectivity to the server hosting the RCF.

    This example verifies that the switch can reach the server at IP address 172.19.2.1:

    cs2# ping 172.19.2.1
Pinging 172.19.2.1 with 0 bytes of data:

Reply From 172.19.2.1: icmp_seq = 0. time= 5910 usec.

  3. Copy the RCF to the Nexus 92300YC switch:

    cs2# copy sftp: bootflash: vrf management
Enter source filename: /code/Nexus_92300YC_RCF_v1.0.2.txt
Enter hostname for the sftp server: 172.19.2.1
Enter username: user1

Outbound-ReKey for 172.19.2.1:22
Inbound-ReKey for 172.19.2.1:22
user1@172.19.2.1's password:
sftp> progress
Progress meter enabled
sftp> get   /code/Nexus_92300YC_RCF_v1.0.2.txt  /bootflash/nxos.9.2.2.bin
/code/Nexus_92300YC_R  100% 9687   530.2KB/s   00:00
sftp> exit
Copy complete, now saving to disk (please wait)...
Copy complete.

  4. Merge the RCF with the running-config of the switch:

    cs2# copy bootflash:Nexus_92300YC_RCF_v1.0.2.txt running-config

Disabling ssh: as its enabled right now:
 generating ecdsa key(521 bits)......
generated ecdsa key

Enabling ssh: as it has been disabled
 this command enables edge port type (portfast) by default on all interfaces. You
 should now disable edge port type (portfast) explicitly on switched ports leading to hubs,
 switches and bridges as they may create temporary bridging loops.

Edge port type (portfast) should only be enabled on ports connected to a single
 host. Connecting hubs, concentrators, switches, bridges, etc...  to this
 interface when edge port type (portfast) is enabled, can cause temporary bridging loops.
 Use with CAUTION

Edge Port Type (Portfast) has been configured on Ethernet1/1 but will only
 have effect when the interface is in a non-trunking mode.

Copy complete, now saving to disk (please wait)...
Copy complete.

  5. Verify on the switch that the RCF has been merged successfully:

    show running-config

    cs2# show running-config
!Command: show running-config

  6. Save the running configuration so that it becomes the startup configuration when you reboot the switch:

    cs2# copy running-config startup-config

  7. For ONTAP 9.6P8 and later, enable the Ethernet switch health monitor log collection feature for collecting switch-related log files, using the commands: system cluster-switch log setup-password and system cluster-switch log enable-collection

    cluster1::*> system cluster-switch log setup-password
Enter the switch name: <return>
The switch name entered is not recognized.
Choose from the following list:
cs1
cs2

cluster1::*> system cluster-switch log setup-password

Enter the switch name: cs1
RSA key fingerprint is e5:8b:c6:dc:e2:18:18:09:36:63:d9:63:dd:03:d9:cc
Do you want to continue? {y|n}::[n] y

Enter the password: <enter switch password>
Enter the password again: <enter switch password>

cluster1::*> system cluster-switch log setup-password

Enter the switch name: cs2
RSA key fingerprint is 57:49:86:a1:b9:80:6a:61:9a:86:8e:3c:e3:b7:1f:b1
Do you want to continue? {y|n}:: [n] y

Enter the password: <enter switch password>
Enter the password again: <enter switch password>

cluster1::*> system cluster-switch log enable-collection

  8. Reboot the switch and verify that the running configuration is correct:

    reload

    cs2# reload

This command will reboot the system. (y/n)?  [n] y
