Upgrade RCF files on MetroCluster IP switches
You might need to upgrade an RCF file on a MetroCluster IP switch. For example, an ONTAP upgrade or a switch firmware upgrade both require a new RCF file.
Ensure that the RCF file is supported
If you are changing the ONTAP version running on the switches, you should ensure that you have an RCF file that is supported for that version. If you use the RCF generator, the correct RCF file will be generated for you.
Use the following commands from the switches to verify the version of the RCF file:
From this switch…
Issue this command…
(IP_switch_A_1) # show clibanner
IP_switch_A_1# show banner motd
For either switch, find the line in the output that indicates the version of the RCF file. For example, the following output is from a Cisco switch, which indicates the RCF file version is “v1.80”.
Filename : NX3232_v1.80_Switch-A2.txt
To check which files are supported for a specific ONTAP version, switch, and platform, use the RcfFileGenerator. If you can generate the RCF file for the configuration that you have or that you want to upgrade to, then it is supported.
To verify that the switch firmware is supported, refer to the following:
Upgrade RCF files
If you are installing new switch firmware, you must install the switch firmware before upgrading the RCF file.
This procedure disrupts traffic on the switch where the RCF file is upgraded. Traffic will resume once the new RCF file is applied.
Verify the health of the configuration.
Verify that the MetroCluster components are healthy:
metrocluster check run
cluster_A::*> metrocluster check run
The operation runs in the background.
metrocluster check runoperation completes, run
metrocluster check showto view the results.
After approximately five minutes, the following results are displayed:
----------- ::*> metrocluster check show Last Checked On: 4/7/2019 21:15:05 Component Result ------------------- --------- nodes ok lifs ok config-replication ok aggregates warning clusters ok connections not-applicable volumes ok 7 entries were displayed.
Check the status of the running MetroCluster check operation:
metrocluster operation history show -job-id 38
Verify that there are no health alerts:
system health alert show
Prepare the IP switches for the application of the new RCF files.
Follow the steps for your switch vendor:
Download and install the IP RCF file, depending on your switch vendor.
Update the switches in the following order: Switch_A_1, Switch_B_1, Switch_A_2, Switch_B_2
Downloading and installing the Cisco IP RCF files
If you have an L2 shared or L3 network configuration, you might need to adjust the ISL ports on the intermediate/customer switches. The switchport mode might change from 'access' to 'trunk' mode. Only proceed to upgrade the second switch pair (A_2, B_2) if the network connectivity between switches A_1 and B_1 is fully operational and the network is healthy.
