You can duplicate a specified port configuration on specified target ports using the
clone config port command. The following example configures ports 8–19 based on port 0:
8/20q FC Switch #> admin start
8/20q FC Switch (admin) config edit
8/20q FC Switch (admin) #> clone config port 0 8-19
8/20q FC Switch (admin-config)#> config save
8/20q FC Switch (admin)#> config activate
8/20q FC Switch (admin)#> admin end
The following example temporarily changes the administrative state of port 1 to down:
8/20q FC Switch #> admin start
8/20q FC Switch (admin) #> set port 1 state down

Configuring transparent routing

IMPORTANT:
8/20q Fibre Channel Switches with active TR_Ports; however, SSCM cannot manage or discover remote
switches or devices in the remote fabric. Use QuickTools or Enterprise Fabric Management Suite and the
storage management interface to present Logical Unit Numbers (LUNs) to remote devices. SSCM version
2.0 and earlier versions do not support the management of fabrics that include 8/20q Fibre Channel
Switches with active TR_Ports and may disrupt communication between the 8/20q Fibre Channel Switch
and the remote fabric.
The transparent routing feature provides inter-fabric routing to allow controlled and limited access between
devices on a 8/20q Fibre Channel Switch (local) fabric and devices on a remote fabric consisting of
switches made by other vendors. For a list of switches that are supported in a remote fabric, see the HP
StorageWorks 8/20q Fibre Channel Switch release notes, and the HP StorageWorks SAN Design
Reference Guide located at the HP website: http://www.hp.com/go/sandesignguide. This type of
inter-fabric connection uses the Fibre Channel industry N-Port ID Virtualization (NPIV), and makes local
and remote devices accessible to each other while maintaining the local and remote fabrics as separate
fabrics.
You can connect multiple 8/20q Fibre Channel Switches to one or more remote fabrics using multiple
TR_Ports. Local and remote devices are identified by their respective port worldwide names. Consider the
following mapping rules:
A TR_Port can support a maximum of 32 local device/remote device mappings.
A specific local device can be mapped to devices on only one remote fabric. Local devices on the same
8/20q Fibre Channel Switch can each be mapped to different remote fabrics.
For mappings between a specific 8/20q Fibre Channel Switch and a remote fabric, each local device
or remote device can be mapped over only one TR_Port. Additional mappings to either device must use
that same TR_Port.
Mulitple local devices connected to different local switches can be mapped to the same remote device
over one TR_Port on each local switch.
A local device cannot be mapped over an E_Port to another local switch, then over a TR_Port to the
remote device. The local switch to which the local device is connected must connect directly to the
remote fabric over a TR_Port.
NOTE:
TR_Port appear as an NPIV connected device in the remote fabric. It is possible, though not
recommended, to map such a local device over a second TR_Port to a local device in a second
local fabric. In this case, if you merge the two local fabrics, the transparent route becomes inactive
for the devices that now have a path over an ISL, and an alarm is generated.
