IBM SAN48B-5, Installation, Service And User Manual

Page: 48 / 84

– For general information and details on using Access Gateway, refer to the
Access Gateway Administrator’s Guide .
– For specific instructions to prepare the edge fabric before connecting it to
Access Gateway (since Access Gateway relies on NPIV technology for its
connection to the edge fabric), refer to the
Access Gateway Administrator’s Guide
Note: Access Gateway cannot be connected directly into an array. It requires a
fabric to support NPIV.
v Fabric OS features available to the switch depend on whether the switch is
configured in Access Gateway or Fabric OS Native mode. For a list of available
features for each mode, refer to the
Access Gateway Administrator’s Guide .
v
In Access Gateway mode, cascading is not available for the SAN48B-5. Refer to
the latest
Access Gateway Administrator’s Guide for details on any other
restrictions specific to the SAN48B-5.
v
In Fabric OS Native mode, the switch provides up to eight external Fibre
Channel ports. These universal and self-configuring ports are capable of
becoming one of the following port types:
– F_Port (fabric enabled)
– FL_Port (fabric loop enabled)
– E_Port (expansion port)
– M_Port (mirror port)
v
In Access Gateway mode, the switch also provides up to eight external Fibre
Channel ports. However, these ports are configured as N_Ports, and you cannot
reconfigure these as any other port type.
Disabling and enabling Access Gateway mode
This section provides steps to disable and enable Access Gateway mode using
Fabric OS commands. For more information on using these commands, refer to the
“Enabling and disabling Access Gateway mode” section in the
Access Gateway
Administrator’s Guide or the Fabric OS Administrator’s Guide .
Note: You can also disable and enable Access Gateway mode using Web Tools. See
the
Web Tools Administrator’s Guide for more information.
Enabling Access Gateway mode
Note the following information when enabling Access Gateway (AG) mode:
v
After you enable AG mode, some fabric information is erased, such as the zone
and security databases.
v
Enabling AG mode is disruptive because the switch is disabled and rebooted.
v
Ensure that no zoning or Admin Domain (AD) transaction buffers are active. If
any transaction buffer is active, enabling Access Gateway mode will fail with the
error, “Failed to clear Zoning/Admin Domain configuration.”
Use the following steps to enable Access Gateway mode using Fabric OS
commands. For more information on enabling Access Gateway mode, refer to
“Enabling and disabling Access Gateway mode” in the
Access Gateway
Administrator’s Guide .
1. Before disabling a switch to enable Access Gateway mode, save the current
configuration file using the
configUpload command in case you need this
configuration again.
2. 2. Enter the switchShow command to verify the switch mode.
