110 Chapter 4 Managing Clients and Users
Setting Up Access Control Lists
You can use Mac OS X Server’s Workgroup Manager to control access to SAN volumes
and folders on those volumes using access control lists (ACLs).
To set up the access control list for a volume or folder:
m Make sure ACLs are enabled on the volume. For help, see “Enabling or Disabling Access
Control Lists” on page 100. Then open Workgroup Manager and click Sharing. Select
the SAN volume or folder, click Access, and drag user or group names to the access
control list. For more information, see the Workgroup Manager onscreen help.
Unmounting a Volume on a Client
To prevent a client from accessing a volume, you can unmount the volume from the
client. Clients can’t mount SAN volumes themselves; only an administrator can mount a
SAN volume on a client.
To unmount a volume:
1 Open Xsan Admin, select the volume, and click Clients.
2 Select the client computer in the list and click Unmount.
Restricting a Client to Read-Only Access
To prevent a user logged in to a client computer from modifying data on a SAN
volume, you can mount the volume on the client with read-only permissions.
To grant read-only volume access:
1 Open Xsan Admin, select the volume, and click Clients.
2 Select the client computer.
3 If the volume is already mounted on the client, click Unmount.
