100 Chapter 3 Managing SAN Storage
Enabling or Disabling Access Control Lists
You can use Xsan Admin to specify whether the Xsan file system uses access control
lists (ACLs) on a volume.
To use ACLs, your SAN controller must be running Xsan 1.4. Only Xsan 1.4 clients and
Windows StorNext clients recognize ACLs. (ACLs on Xsan volumes are ignored by UNIX
clients as well as clients running Xsan 1.3 or earlier.) If you have a mix of Windows
clients and Xsan clients, they must all be bound to the same directory domain, whether
provided by Open Directory configured as a Primary Domain Controller (PDC), by
Windows Active Directory, or by Windows NT PDC.
Note: If you enable ACLs but your SAN includes clients that don’t support them, don’t
use those clients to change ownership information or inconsistencies might result.
To enable or disable ACLs:
1 In Xsan Admin, select the volume in the SAN Components list, click Clients, and
unmount the volume from all clients and controllers.
2 Click Stop Volume.
Important: If you forget to unmount the volume (in step 1) before you stop it, be sure
to click Disconnect in the “server no longer available” alert that appears on any
computer that has the volume mounted.
3 Select the SAN that the volume belongs to, click Setup, and click Storage.
4 Double-click the volume in the list.
5 Set or clear the checkbox next to Access Control Lists and click OK.
