Chapter 2 Setting Up a Storage Area Network 37
Step 14: (Optional) Set User and Group Quotas
You can set up quotas to control how much space in each SAN volume is used by each
user or group.
1 If the volume is not already started, select it in the SAN Components list and click Start
Volume.
2 With the volume still selected, click Quotas.
3 Click the Add (+) button, then drag a user or group from the drawer to the quotas list.
If you don’t see the SAN users in the drawer, open Directory Access (in
/Applications/Utilities) and make sure you’re using the correct directory for user
authentication.
4 Select the user or group in the quotas list and adjust their quota settings in the lower
half of the window.
Soft Quota: The user’s recommended working maximum. The user can exceed this
limit as needed, but only for the length of time specified following “Quota locked after.”
Hard Quota: The absolute maximum amount of storage the user’s data can occupy.
“Quota locked after...”: The length of time the user can exceed their soft quota before
it automatically becomes a hard quota.
Step 15: Start the Volumes and Mount Them on Clients
To make a volume available to a user or application on a client computer, you must use
Xsan Admin to start the volume and mount it on the client. Users logged in to client
computers can’t browse for or mount SAN volumes themselves.
1 In Xsan Admin, select each new volume in the SAN Components list and click Start
Volume.
If you set up affinities or quotas on the volume, you have already started it.
2 With the volume still selected, click Clients.
3 Select a client computer and click Mount Read & Write.
To prevent the client from modifying the volume, click Mount Read Only after you click
Mount Read & Write.
Shift-click computers to mount on more than one at a time.
An icon for the mounted volume appears in the Finder on each client computer.
If you’re unable to mount volumes on any client, try shutting down all clients and
controllers, restarting the controller first and then the clients, and mounting again. If
you still have trouble, check your Fibre Channel switch configuration to be sure that the
SAN’s clients, controllers, and storage devices are in the same Fibre Channel zone.
