IBM SAN24B-5 - Enabling and Disabling Access Gateway Mode

– 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 24 external Fibre
Channel ports. However, these ports are configured as N_Ports, and you cannot
reconfigure these as any other port type.
Enabling and disabling Access Gateway mode
This section provides steps to enable and disable 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 enable and disable Access Gateway mode using Web Tools. See
the Web Tools Administrator’s Guide for more information.
Enabling Access Gateway mode
Note the following when enabling Access Gateway mode:
v After you enable Access Gateway mode, some fabric information is erased, such
as the zone and security databases.
v Enabling Access Gateway 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.
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 at a later time.
2. 2. Enter the switchShow command to verify the switch mode.
v Access Gateway Mode displays for switchMode if the switch is in Access
Gateway mode.
v Native displays for switchMode if the switch is in Fabric OS Native mode.
3. Enter switchDisable to disable the switch. Access Gateway mode can only be
enabled or disabled when the switch is in a disabled state.
4. Enter ag –modeEnable to enable Access Gateway mode.
5. Enter the ag --modeShow command to verify that AG mode is enabled.
switch:admin> ag --modeshow
Access Gateway mode is enabled.
Disabling Access Gateway mode
When you disable Access Gateway mode, the switch automatically reboots and
comes back online using the fabric switch configuration. The Access Gateway
parameters, such as F_Port-to-N_Port mapping, Failover, and Failback are
automatically removed. When the switch reboots, it starts in Fabric OS Native
mode. To re-join the switch to the core fabric, refer to the Access Gateway
Administrator’s Guide.
