Change cluster IP address to different network

Japanese_human8888 — Wed, 04 Jun 2025 10:27:12 GMT

I'm new to NetApp and I'm looking for the procedure to change the IP address of the cluster network on a NetApp FAS 2552.

now cluster IP address:169.254.0.0/16
new cluster IP address:192.168.10.0/24

The problem is the following.
===
FAS2552-02-cluster::*> network interface modify -vserver Cluster -lif FAS2552-02-cluster-01_clus1 -address 192.168.10.0 -netmask 255.255.255.0

Warning: Changes to a cluster LIF can affect the health of the Cluster. Are you sure you want to
continue? {y|n}: y

Error: command failed: Since masking an address with a netmask represents an entire IP subnet, the
masked and unmasked IP addresses cannot be the same.

===
FAS2552-02-cluster::*> network interface show -role cluster

up/up 169.254.249.1/16 FAS2552-02-cluster-02
e0f true
4 entries were displayed.

Is there a way to achieve my goal?
Thank you in advance.

Hi there,

The cluster network is internal only - it is created using setup, and uses IPSpaces, so it doesn't matter if you are using the same IP space on another part of your network (which you shouldn't be anyway, since it's in the link local scope, which should never be routed..).

I strongly caution you not to change the Cluster IP addresses.

..that said, as the CLI says, the error with the commands you have provided is that you are not specifying the IP address you want to change it to, just the subnet.

Can I ask why you want to change the IPs?

Cluster IPs are used for backend communication between nodes - for administration of nodes, you want to have Node Management IPs and a Cluster Management IP. Those ones you can change if you want.

Hello.
Thank you for your answer.

I'm sorry.
I was pasting different results.
What I wanted to show is the following result.
===
FAS2552-02-cluster::> network interface modify -vserver Cluster -lif FAS2552-02-cluster-01_clus1 -address 192.168.10.1 -netmask 255.255.255.0

Warning: Changes to a cluster LIF can affect the health of the Cluster. Are you sure you want to
continue? {y|n}: y

Error: command failed: Cluster LIFs must be in the same subnet. Verify the address and netmask
are set to the correct values.
===

The reason I want to change IPs is because I want to change the address to something other than a link-local address in order to migrate from a switchless cluster to a switched cluster.

Ah.

Please follow the instructions in this document to move from a switchless to switched cluster - https://library.netapp.com/ecm/ecm_get_file/ECMP1140535 if you have CN1610 switches, or https://docs.netapp.com/platstor/index.jsp?topic=%2Fcom.netapp.doc.hw-sw-ix8-migrate-2n%2FGUID-81FD5EDF-8902-40EA-9050-69358426CB6F.html&lang=en for BES53248 switches (or review these search results for Cisco switches)

You will not need to change the Cluster IPs. Please follow the instructions exactly, or there may be a data service or cluster outage.

Hope this helps!

hello.

Even if I didn't change the cluster IPs, I success it according to the instructions you taught me.

I'd like to thank you from the bottom of my heart.
