10. Reboot the host.
What Next? The next step depends on the topology:
◆ FC-AL: Proceed to Preparing the Server on page 3-18.
◆ FC-SW: Proceed to Preparing the Fabric on page 3-15.
Preparing the Fabric You can configure a switched fabric to support multiple hosts and
multiple storage systems. For this setup, we will describe only the
minimum configuration required for the boot LUN and server.
EMC recommends that you use switch zoning in all configurations to
ensure consistency if your fabric grows.
The configuration below requires an existing knowledge of zoning and
switch fabric concepts. The procedure explains the necessary steps to enable
boot functionality for the storage system. This configuration does not cover
the impact of zoning changes to other devices that will use the same
connections. You should confirm your overall topology requirements and
configuration before implementing any zoning changes.
Other devices on the fabric may introduce load and demand on the interlink
components and storage system that can affect boot LUN performance and
correct functionality.
The switch fabric must be configured initially so that the boot HBA is
visible only to a single port on the storage system. That is, there must
be only one zone containing the boot HBA and one SP port until
installation is complete, even if you will install failover software later.
This can be accomplished in one of three ways (described following
this list):
◆ Switch fabric soft zoning (by WWPN)
◆ Switch fabric hard zoning (by switch port)
◆ Physical connection of only one SP port to the fabric
