Fault Isolation And Security - HP StorageWorks 2/16 - SAN Switch User Manual

If legacy private hosts or private storage devices have difficulty with U_Port
initialization, use the portCfgLport command to configure the port as a loop-only
port.

Fault Isolation and Security

The components of the Fabric Assist mode zone can be specified as either a port
address (hard zoning) or as a WWN (soft zoning). If you specify a WWN, the
Name Service guarantees that the associated device is automatically configured
into the zone wherever it is found in the Fabric. Currently, hard zoning is more
secure than soft zoning.
The creation of separate Fabric Assist mode zones for each host provides superior
fault isolation over emulated loop environments.
Quickloop Fabric Assist User Guide
A fabric can have virtually unlimited number of Fabric Assist host loops.
A Fabric Assist zone is defined by listing zone members by World Wide
Name (WWN) or by fabric port number. If defined with a fazoneCreate
telnet command, the private host is identified with "H{ }" notation in its
WWN or fabric port designation. If the private host WWN is used, a Fabric
Assist zone is automatically configured when that comes online anywhere in
the fabric.
A Fabric Assist mode private host may or may not be registered in the Name
Server, allowing the user to monitor its status. This depends on whether or not
the private host responds to the switch's PLOGI request.
Fabric Assist mode supports all Zoning features such as Zoning
Configurations, Zone Aliases to specify common elements, and fabric-wide
distribution.
A Fabric Assist zone may be grouped with other zones and placed within
various configurations. The Fabric Assist zone telnet commands are described
in Using QuickLoop Fabric Assist Mode,
