Hello @luciferHK 

I just tested this on my lab and this is what i got bellow; It should be possible as well as for Node

In case you dont see the screenshot, here us the output text. Might be distorted.

The cluster_mgmt_2 is the new cluster LIF(IP) i just created

I have done more than one cluster ip. Useful during migrations. Have a cluster split between two buildings. The mgmt networks are different so we have two cluster ip addresses. The nodes on either side continue with one ip. They really do not more than one. Will be removing nodes and then deleting the cluster ip in the older building

Yes, not common, but some customers have a private storage VLAN/subnet, but want access for management from the corporate network. I've seen it. I remember specifically because we had to do a perfstat with all the corporate node management LIF IPs instead of specifying cluster management IP. The perfstat was trying to connect to the storage network node-managment LIFs and taking twice as long!
