Step 2: Disable Spotlight on all volumes
If you’re going to upgrade your SAN computers to Mac OS X v10.6, disable Spotlight on
all Xsan volumes during the upgrade. If you’re upgrading only Xsan but not Mac OS X,
skip this step.
To disable Spotlight on a volume:
Open your current version of Xsan Admin.
In Xsan Admin, select Volumes in the SAN Assets list.
Select the volume and choose Edit Volume Settings from the Action (gear) pop-up
Click to deselect “Enable on this volume” next to Spotlight.
