Apple Xsan 2 - Manual (Page 132)

132 Appendix A Upgrade to Xsan 2.3
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.
Step 9: Reenable Spotlight
If you disabled Spotlight to upgrade SAN computers to Mac OS X Lion or Lion Server,
reenable it now.
Enable Spotlight on 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 Click to select “Enable on this volume” next to Spotlight.
Upgrade SAN hardware and software
Follow these instructions if, as part of your Xsan 2.3 upgrade, you must replace
