Modifying metadata server zoning and LUN masking

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.

If you are using LUN masking, you want to unassign the volumes comprising the user storage pools from the metadata servers.
Attention: You must not unassign or zone off a system storage pool LUN from the metadata server or you will lose your SAN File System cluster.

Refer to the documentation for your SAN switches and storage subsystems for information about zoning.
