HP StorageWorks Fabric OS 6.x administrator guide (5697-7344, March 2008)

46 Standard features
Any number of E_Ports in a fabric can be configured for gateway links, provided the following rules
are followed:
All switches in the fabric must be upgraded to Fabric OS 5.2.0 or later.
All switches in the fabric are using the core PID format.
The switches connected to both sides of the gateway are included when determining switch count
maximums.
Extended links (those created using the Extended Fabrics licensed feature) and the security features if
you are running a Fabric OS version earlier than 6.x in Secure Fabric OS are not supported through
gateway links.
To configure a link through a gateway:
1. If you are not sure if the PID format is consistent across the entire fabric, enter the configShow
command on all switches to check the PID setting. If necessary, change the PID format on any
nonconforming switches, as described in ”Configuring the PID format” on page 463.
2. Connect to the switch on one end of the gateway and log in using an admin account.
3. Enter the portCfgIslMode command that is appropriate for your hardware model:
4/8 SAN Switch and 4/16 SAN Switch, SAN Switch 2/8V, SAN Switch 2/16V, SAN Switch 2/32,
Brocade 4Gb SAN Switch for HP p-Class BladeSystem, Brocade 4Gb SAN Switch for HP c-Class
BladeSystem, SAN Switch 4/32, 4/64 SAN Switch, SAN Switch 4/32B, and 400 Multi-protocol
Router:
portCfgIslMode <port, mode>
Specify a port number. Valid values for port number vary depending on the switch type. The mode
operand is required: specify 1 to enable ISL R_RDY mode (gateway link) or specify 0 to disable it.
4/256 SAN Director and DC SAN Backbone Director (short name, DC Director):
portCfgIslMode <slot/port, mode>
Specify a slot/port number pair. Valid values for slot and port number vary depending on the switch
type. The mode operand is required: specify 1 to enable ISL R_RDY mode (gateway link) or specify 0 to
disable it.
In the following example, slot 2, port 3 is enabled for a gateway link:
switch:admin> portcfgislmode 2/3, 1
Committing configuration...done.
ISL R_RDY Mode is enabled for port 3. Please make sure the PID
formats are consistent across the entire fabric.
switch:admin>
4. Repeat the steps for any additional ports that will be connected to the gateway.
5. Repeat the procedure on the switch at the other end of the gateway.
Checking status
You can check the status of switch operation, High Availability features, and fabric connectivity.
To check switch operation:
1. Connect to the switch and log in using an admin account.
2. Enter the switchShow command. This command displays a switch summary and a port summary.
3. Check that the switch and ports are online.
4. Use the switchStatusShow command to further check the status of the switch.
High Availability (HA) features provide maximum reliability and nondisruptive replacement of key
hardware and software modules.
To verify HA features (Directors only):
1. Connect to the switch using an account with admin role
2. Enter the chassisShow command to verify the field replaceable units (FRUs).
