This topic provides information to help you determine whether you
need to a default storage pool and what storage pools can be used.
If you intend to configure all SAN File System clients to see all storage
volumes, you can set one storage pool to be the default storage pool. Files
created by a client that do not meet any of the rules in the active policy
set will be stored in this storage pool.
If you configure your SAN clients and storage volumes into zones so that
clients can see only a subset of all storage volumes, you will not be able
to set a default storage pool. In this case, you can choose between two
options:
- Configure a single storage pool that is accessible from all client zones
(each of the volumes in that storage pool must be accessible from all clients).
Then, you can define a default rule in the active policy set so that if a
file does not meet any of the other rules in the policy set, it is stored
in the default storage pool.
- Create a single storage pool for each client zone that can be used like
a default storage pool. Again, you must define a default rule in the active
policy set for each set of clients in each zone so that if, for a particular
zone, a file does not meet any of the other placement rules, it will be placed
in this storage pool.
If a client attempts to create a file and there is no policy set rule for
placing that file into a storage pool, the SAN File System will generate an
error.
