Apple Xsan 2 - Manual (Page 82)

Enable or disable access control lists
You can use Xsan Admin to specify whether the Xsan file system uses access control
lists (ACLs) on a volume.
Xsan 2 clients and Windows StorNext clients recognize ACLs. UNIX clients ignore ACLs
on Xsan volumes. 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) or by Windows Active Directory.
Note: If you enable ACLs but your SAN includes clients that don’t support them, don’t
use those clients to change file or folder ownership information, or inconsistencies
might result.
Enable or disable ACLs:
1 In Xsan Admin, select Volumes in the SAN Assets list.
2 Select the volume and choose Edit Volume Settings from the Action pop-up menu (gear).
3 Select or deselect the checkbox next to Access Control Lists and click OK.
Note: After you click OK, the volume is unmounted from all SAN computers, and then
remounted.
Change filename case sensitivity
If all the computers on your SAN have Mac OS X Lion or Lion Server, you can specify
whether a volume ignores capitalization in filenames. For example, a volume can
consider myfile, MyFile, and MYFILE to be the same or different filenames. This option is
on by default if the SAN consists only of Macs with Lion.
For best performance with volumes that you share using the SMB protocol, make them
case insensitive.
Change filename case sensitivity for a volume
1 In Xsan Admin, select Volumes in the SAN Assets list.
2 Select the volume and choose Edit Volume Settings from the Action pop-up menu (gear).
3 Select or deselect the checkbox next to Case Insensitivity and click OK.
When you change case sensitivity, Xsan checks all existing filenames to make sure the
change won’t result in filenames being considered the same. This check can take a while.
If Case Insensitivity is selected, the volume considers filenames to be the same if they’re
spelled alike but capitalized differently.
If Case Insensitivity is not selected, the volume considers filenames to be different if
they’re spelled alike but capitalized differently.
Note: After you click OK, the volume is unmounted from all Xsan computers, and then
remounted..
