Create an Xsan SAN in macOS Server
These instructions assume that you’ve already gone through the initial steps of setting up your SAN environment. If you aren’t sure, see First-time Xsan SAN setup in macOS Server for a list of prerequisites to this task.
You should already have:
The physical networking infrastructure properly installed
The storage devices prepared as LUNs
The Open Directory Master domain enabled on the primary controller (optional)
The planning questions in Plan your Xsan SAN answered.
Important: Some types of SAN reconfiguration destroys the SAN and the stored data. Plan carefully so you can avoid data loss.
Set computer sleep to Never in the Energy Saver pane of System Preferences.
In the Server app sidebar, select Xsan from the list of advanced services.
Turn on the service.
The Xsan setup assistant appears.
Choose “Create a new SAN,” then click Next.
If you start to create a SAN without Open Directory enabled, the Xsan setup assistant will also include Open Directory setup steps.
Give the SAN a unique name on your network.
Enter the directory administrator’s login name and password.
This login was specified when you created the Open Directory Master.
When setup completes, you should add at least one volume.
For volume creation options and instructions, see Create an Xsan volume in macOS Server.
The controller has an Xsan configuration profile generated as part of creating the SAN. Similar to clients, removing the configuration profile from a controller removes it from the SAN. This operation cannot be undone.
