Before you begin
A SAN created in OS X Yosemite or later automatically selects the server’s public network for Xsan metadata traffic. You can select a private metadata network after a SAN has been created using the steps in this article.
All Xsan metadata controllers must be using OS X Yosemite 10.10.2 or later before performing these steps. When using a private metadata network, all members of the SAN must be connected to both your public and private networks.
Change the Xsan metadata network
Use the following terminal command on each Xsan MDC in your SAN. Replace oldIP with the IP address of the MDC on your public network and newIP with its IP address on the private network you want to use for your Xsan metadata traffic.
sudo xsanctl changeIP oldIP newIP
