Chapter 3 Setting Up a Storage Area Network 47
Spotlight: Enable this if you want Macintosh clients to search the contents of the
volume using Spotlight.
Extended Attributes: Select this option if all computers on your SAN are running
Xsan 2.2 and you want to ensure the best possible performance by storing related
information for each le inside the le itself instead of in separate hidden les.
This option is enabled by default if the SAN consists of all Xsan 2.2 systems.
Access Control Lists: Leave this enabled if you want to use access control lists to
control access to the volume and its contents.
Windows ID Mapping: If you have Windows clients on your SAN, choose how they
map user and group information to the Xsan-compatible user IDs and group IDs they
need to access this volume. For more information, see “Mapping Windows User and
Group IDs” on page 78.
3 In the Congure Volume Anities pane (or the Congure Volume Storage pane,
if you’re conguring a custom volume type), drag LUNs from the left column to the
corresponding anity tag (or custom storage pool) in the right column.
a Drag the special metadata LUN you created (in Step 6, “Create a Metadata Array”) to
the MetadataAndJournal anity tag (or custom storage pool).
b Drag your other LUNs to the other anity tags (or storage pools). To avoid
wasting storage, all LUNs assigned to an anity tag (or storage pool) should be
the same size.
c When you nish, click Continue.
For information about the optimal number of LUNs to assign to an anity tag,
see “Assigning LUNs to Anity Tags” on page 29.
4 Optionally, you can select an anity tag and click Settings to change the anity tag
name or other settings listed below. If you’re creating a custom volume, you can select
it and click Storage Pool Settings to change the storage pool name or other settings
listed below.
Anity Tag (or Storage Pool Name): Enter the name for the anity tag (or custom
storage pool). If the OK button is disabled when you nish entering the name, the
name is reserved; try another. For a list of reserved names, see Chapter 8, “Solving SAN
Problems.”
Use for: Choose the types of data that can be stored on storage pools that have this
anity tag (or that can be stored on the custom storage pool). If the “Only data with
anity” checkbox is disabled, this might be the only storage pool in the volume that
can store user data without an anity. You must have at least one storage pool that
isn’t exclusive, that is, a storage pool that can store user data that has no anity.
