Multi-Switch Fabrics; Software Diagnostics - HP StorageWorks Edge Switch 2/12 Installation Manual

Zones are grouped into zone sets. A zone set is a group of zones that is enabled
(activated) or disabled across all switches in a multi-switch fabric. Only one zone
set can be enabled at one time.

Multi-Switch Fabrics

A Fibre Channel topology that consists of one or more interconnected switches or
switch elements is called a fabric. Optional E_Port (Full-Fabric) feature key
provides the ability to interconnect switches (through E_Port connections) to form
a multi-switch fabric. The data transmission path through the fabric is typically
determined by fabric elements and is user-transparent. Subject to zoning
restrictions, devices attached to any interconnected switch can communicate with
each other through the fabric.

Software Diagnostics

The switch provides the following diagnostic software features that aid in fault
isolation and repair of problems:
Edge Switch 2/12 Installation Guide
Caution: If zoning is implemented by port number, a change to the switch
fiber-optic cable configuration disrupts zone operation and may incorrectly
include or exclude a device from a zone.
If zoning is implemented by WWN, removal and replacement of a device
HBA or Fibre Channel interface (thereby changing the device WWN) disrupts
zone operation and may incorrectly include or exclude a device from a zone.
In Open Fabric mode, only zoning by WWN is supported. Zoning by port
numbers is not.
SFP transceivers provide on-board diagnostic and monitoring circuits that
continuously report status to the EWS interface. The interface provides
system alerts and logs that display failure and diagnostic information.
The EWS interface that provides Ethernet access to isolate problems for a
single switch.
Unsolicited SNMP trap messages that indicate operational state changes or
failures and can be transmitted to up to six authorized management
workstations.
