Maintenance operations require the use of a computer, with an Ethernet interface.
Chapter 4 Fabric Setup
4.2 Setting Up the Fibre Channel Switches
(2) Turn on the Fibre Channel switch.
The Fibre Channel switch runs POST automatically after the power is turned on. During phase, the Fibre Channel port LED blinks continuously.
2 Set the IP address of the maintenance computer.
To perform Ethernet connections with a Fibre Channel switch and cross cable, change the IP address on the maintenance computer to correspond with the IP address of the Fibre Channel switch (default). (To change, follow the instructions in the computer).
(1) Start Windows® and open the control panel.
Click [Settings]-[Control Panel] from [Start] button.
(2) Click [Network] in the [Control Panel].
(3) Select [Network Settings], then select "TCP/IP->*********" in [Current Network Components], and click [Properties].
(The (*********) part is the "TCP/IP protocol LAN controller" for the computer that you are using.) (4) Select [IP Address] in [TCP/IP Properties], check [Specify IP Address], and then enter the IP address
and the net mask that are assigned to the terminal used for maintenance.
Do not assign an IP address that has already been assigned to some other device, like a Fibre Channel switch.
(5) Click the [OK] button. The "Restart Windows?" message is displayed; click the [Yes] button.
The IP address for the maintenance computer has been set when Windows® has restarted.
Example:
For the ETERNUS SN200 series, as the default IP address for the Fibre Channel switch is "192.168.30.70", the maintenance computer should be assigned an IP address such as "192.168.30.80".
3 Set the IP address for the Fibre Channel switch (Network Settings).
For the ETERNUS SN200 series, the factory set default IP address is as follows;
• IP address: 192.168.30.70
• Netmask: 255.255.255.0
4 Start the MS-DOS prompt for the maintenance computer, and use the "ping" command to check if the Fibre Channel switch and the maintenance computer are connected.
• Example: When using ETERNUS SN200 (1) Start MS-DOS prompt.
(2) Execute the following command if the Fibre Channel switch IP address is "192.168.30.70".

Do the settings in the same way for SN200_2.
5 Check the WWN
Check the Fibre Channel switch device WWN through the device itself, and then enter it in the Fibre Channel switch settings table.
The device WWN can be checked by connecting to the Fibre Channel switch with telnet connection. If the IP address was changed in Step (2), then connect with telnet to the new IP address.
Chapter 4 Fabric Setup
4.2 Setting Up the Fibre Channel Switches
After logging in to connect to telnet, you can check the device WWN by executing the "switchShow"
command.
An example of check results is shown below.
switch:admin> switchShow switchName: switch switchType: 9.2 switchState: Online switchMode: Native switchRole: Principal switchDomain: 1
switchId: fffc01
switchWwn: 10:00:00:60:69:51:1f:f8 switchBeacon: OFF
--- Execute the "switchShow" command
--- Fibre Channel switch WWN (It means Node name)
Enter the Fibre Channel switch WWN to the Fibre Channel switch settings table.
Enter the checked device WWN into the Fibre Channel switch settings table.
The following example is for a SN200_01 based on the system configuration diagram given in
"3.1 Checking the System Configuration" (page 13) (Enter the shaded portions).
• Fibre Channel switch settings table (WWN of SN200_01)

6 Set the switch name.
To set the switch name, log in with telnet to the Fibre Channel switch, and then set each of the Fibre Channel "Switch name" that was entered in the "Fibre Channel switch settings table". Use the
"switchName" command to do the settings.
Chapter 4 Fabric Setup
4.2 Setting Up the Fibre Channel Switches
Command syntax SwitchName "(1)"
(1) Set the switch name that was entered in the Fibre Channel switch settings table.
The following shows an example of changing the switch name.
255.255.255.0
The following shows an example of executing the "switchName" command.
Switch :admin>
Switch :admin> switchName "SN200_01" ---(1) Updating flash ...
SN200_01:admin> switchName ---(2) SN200_01
SN200_01:admin>
(1) Change the switch name to "SN200_01"
(2) Check that the setting has changed 7 Set switch domain ID.
To set the switch domain ID, log in to the Fibre Channel switch with telnet, and then set the "Switch domain ID" that was entered in the "Fibre Channel switch settings table" for each Fibre Channel switch.
The setting uses the "configure" command.
However, to execute the "configure" command, the Fibre Channel switch needs to be disabled, so just before you start, execute the "switchDisable" command. Also, after changing the settings with the
"configure" command, you need to execute the "switchEnable" command.
Chapter 4 Fabric Setup
4.2 Setting Up the Fibre Channel Switches
When connecting Fibre Channel switches in a cascade configuration, assign a different switch do-main ID for each Fibre Channel switch. We also recommend that you assign each switch an individual switch ID for the future, even if the switches are not currently connected by a cascade cable. If Fibre Channel switches with identical switch domain IDs are connected in a cascade configuration, the switch domain ID will automatically be changed to an unrecognized ID, or the synchronized setting information of the switches cannot be collected. In the worst situation, the data may be lost.
A "Switch domain ID" setting modification example is shown below (the shaded cell).
255.255.255.0
The actual command flow is shown for changing the switch domain ID from "10" to "1".

8 If you have multiple Fibre Channel switches, perform the procedures in Step 1 through Step 7 for each switch.
Do the procedures in Step 1 through Step 7 before connecting the cascade cable.
Chapter 4 Fabric Setup
4.2 Setting Up the Fibre Channel Switches
9 Cascade connect the Fibre Channel switches (if cascade connection is to be used).
When connecting Fibre Channel switches in a cascade configuration, connect the cables before doing the zone settings.
If the cascade connections have been made, by setting the zoning for one Fibre Channel switch, the same settings will be automatically propagated to the other Fibre Channel switches.
Connect the Fibre Channel switches in a cascade configuration.
If you have set different zones for the multiple Fibre Channel switches before connecting them in a cascade configuration, the setting information will not be propagated and synchronicity will not be achieved, even if you connect the cascade cable after that.
10 Set the Fibre Channel switch port speed.
For some Host Bus Adapter (HBA) to Fibre Channel switch connections, the link speed is not operator settable. When connecting such an HBA to a Fibre Channel switch, try setting the connected Fibre Channel switch port to the expected link speed.
Use the "portcfgspeed" command to set the connected Fibre Channel switch port. The new speed setting is enabled after the affected port link has been shutdown and restarted.
• Command syntax
portcfgspeed [slotnumber/]portnumber speed_level
slotnumber
Specifies the slot number of the port being set.
Required for switches such as SilkWorm 12000, 24000 and 48000 which have director-type slots.
portnumber
Specifies which port is to be set.
speed_level
Specifies the speed level of the port.
0: Automatic mode. Speed is set automatically, usually to the maximum available speed. May re-sult in an undesired speed being set in some cases.
1: 1Gbit/s mode. Port speed is fixed at 1Gbit/s.
2: 2Gbit/s mode. Port speed is fixed at 2Gbit/s.
4: 4Gbit/s mode. Port speed is fixed at 4Gbit/s.
8: 8Gbit/s mode. Port speed is fixed at 8Gbit/s.
• Example:
Chapter 4 Fabric Setup
4.2 Setting Up the Fibre Channel Switches
The current port speed settings can be checked by executing the "portcfgshow" command. Executing this command displays the status of each port, with the current port speed setting shown in the "Speed"
line as follows:
AN: Automatic mode. Port speed is set automatically.
1 : 1Gbit/s mode. Port speed is fixed at 1Gbit/s.
2 : 2Gbit/s mode. Port speed is fixed at 2Gbit/s.
4 : 4Gbit/s mode. Port speed is fixed at 4Gbit/s.
8 : 8Gbit/s mode. Port speed is fixed at 8Gbit/s.
For example, a fixed Port#3 speed of 4Gbit/s, with all the other port speeds set to Automatic, will result in the following output:

4.3 Setting Up the Fibre Channel Switch Zoning Functions
Refer to the zoning settings table, WWN instance management table for the server, and WWN instance man-agement table for storage system that you made in the preliminary setup and perform the zone settings. If the Fibre Channel switches are connected in a cascade configuration and you set the zoning for one Fibre Channel switch, the setting information is automatically propagated to the other Fibre Channel switches. So, it is not necessary to duplicate the zone settings for the other Fibre Channel switches.
The following shows the complete flow when doing zone settings connected to telnet.
1 Alias settings
Set symbol names that are intuitive and easy to understand for each port of each Fibre Channel switch.
2 Zone settings
Create the zone using zone members (alias names) set in Step 1.
3 Set the zone configuration
Set one configuration for some zones that were created in Step 2.
4 Enable the zone configuration
Enable the configuration created in Step 3.
Chapter 4 Fabric Setup
4.3 Setting Up the Fibre Channel Switch Zoning Functions
We recommend connecting the Fibre Channel switch cables with cascade connection before setting the zoning. If you have set different zones for the multiple Fibre Channel switches before connecting them in a cascade configuration, the setting information will not be propagated and synchronicity will not be ach-ieved, even if you connect the cascade cable after that.
A setting example based on the zoning settings table created in "3.4.9 Zoning Settings Table" (page 28) is shown.
• Alias settings
Alias member (port number) Alias name (zone member)
SERV1_SLOT0
Zone member (Enter alias name) Zone number Zone name

• Zone configuration settings
Configuration member Configuration name
CONFIG ZONE0; ZONE1; ZONE2; ZONE3
4.3.1 Setting the Alias
Refer to the zoning settings table (alias settings) that you made in the preliminary setup to set an alias for each of the Fibre Channel switches.
Log in to the Fibre Channel switch with telnet to do the alias settings, and register the alias members with the "alias name" that was entered in the "zoning settings table". Use the "aliCreate" command for the set-tings.
Creating, editing and checking aliases are done with the following commands.
• aliCreate
