2.3 Connecting the InServ Storage Server to the Host Server
During this stage connect the InServ Storage Server to the host server directly or to the fabric.
This set of tasks includes physically cabling the InServ Storage Server to the host server or
fabric.
2.4 Setting Up and Zoning the Fabric
Fabric zoning controls which devices have access to each other on the fabric. The required use
of single initiator to single target zoning isolates the host server and InServ Storage Server
ports from Registered State Change Notifications (RSCNs) that are irrelevant to these ports.
You can set up fabric zoning by associating the device World Wide Names (WWNs) or ports
with specified zones in the fabric. Although you can use either the WWN or the port zoning
methods with the InServ Storage Server, the WWN zoning method is recommended because
the zone survives the changes of ports when cables are reconnected on a fabric.
Use the methods provided by the switch vendor to create relationships between host server
HBA ports and storage server ports before you connect the host server HBA ports or InServ
Storage Server ports to the fabric(s).
After connecting each host server HBA port and InServ Storage Server port to the fabric(s),
verify the switch and zone configurations using the InForm CLI
showhost command, to ensure
that each initiator is zoned with the correct target.
In the following explanations an initiator port (initiator for short) refers to a host server HBA
port and a target port (target for short) refers to an InServ Storage Server HBA port.
REQUIRED: When you establish zoning with the InServ Storage Server, there must
only be a single initiator zoned with a single target. If an issue occurs using
another zoning approach, 3PAR may require that you implement this zoning
approach as part of troubleshooting and/or corrective action.
NOTE: In the examples in the following sections, a fabric can be one or more Fibre
Channel switches or directors.
