This topic provides considerations for updating the zoning of the metadata server zones and LUN masking.
In version 1 of the SAN File System, it was recommended that you implement a zone containing the metadata servers in the cluster, the volumes (LUNs) comprising the system storage pool, and volumes comprising the user storage pools. In version 2 of the SAN File System, metadata servers no longer need access to the volumes comprising the user storage pools. It is recommended, but not required, that you modify the metadata server zones to remove all user data LUNs.
Refer to the documentation for your SAN switches and storage subsystems for information about zoning.
