Chapter 4
Setting Up the Server
The server setup will vary according to how the ETERNUS DX/AF storage systems and server are to be connec-
ted. Edit the server's configuration file to match the chosen topology. Configuration files may also differ de-
pending on which Fibre Channel cards are to be used.
There are two possible connection topologies: direct connection and switch connection. Procedures are de-
scribed below. Also refer to the FUJITSU PCI Fibre Channel manuals as necessary.
●For direct connection
Instance name data of the Fibre Channel card is necessary. Refer to the following sections to set.
•"4.1 Creating a WWN Instance Management Table for the Server" (page 9)
•"4.2 Creating a WWN Instance Management Table for Storage System" (page 12)
•"4.4 Setting the Configuration File (fjpfca.conf)" (page 14)
•"4.5 Re-checking the Settings" (page 14)
●For switch connection
The Fibre Channel card Instance name, target WWN, and target ID information are necessary. Check each
item and enter them in the table. Edit the configuration file according to those information and make set-
tings.
Refer to the following sections to set.
•"4.1 Creating a WWN Instance Management Table for the Server" (page 9)
•"4.2 Creating a WWN Instance Management Table for Storage System" (page 12)
•"4.3 Creating a Target Binding Table" (page 13)
•"4.4 Setting the Configuration File (fjpfca.conf)" (page 14)
•"4.5 Re-checking the Settings" (page 14)
4.1 Creating a WWN Instance Management Table for the Server
Create a "WWN instance management table for the server" with information regarding the Fibre Channel
card.
Determine the following information for each Fibre Channel card installed in the server and enter it into a
copy of the "WWN instance management table for the server" (provided in "Appendix A Various Management
Table Templates" (page 25)).
•Physical slot name
•WWN
•Instance name
•Physical path name

Table 4.1 WWN Instance Management Table for the Server
Physical slot name WWN Instance name Physical path name
1Check the instance names.
"fjpfca + instance number" is the format used to represent Fibre Channel card instance names.
The instance number that corresponds to the physical path in which the Fibre Channel card is installed
is stored in the "/etc/path_to_inst" file at the Fibre Channel card driver installation. Extract the necessary
lines using the "grep" command.
# grep "fjpfca" /etc/path_to_inst
Example:
"/pci@6,4000/fibre-channel@2" 1 "fjpfca"
"/pci@4,2000/fibre-channel@1" 0 "fjpfca"
(1) (2)
(1) indicates the physical path name and (2) indicates the instance number.
"fjpfca1" is the instance name of the "/pci@6,4000/fibre-channel@2" path Fibre Channel card.
"fjpfca0" is the instance name of the "/pci@4,2000/fibre-channel@1" path Fibre Channel card.
2Enter the results in "Instance name" and "Physical path name" columns of the "WWN instance manage-
ment table for the server".
Physical slot name WWN Instance name Physical path name
/pci@4,2000/fibre-channel@1
/pci@6,4000/fibre-channel@2
fjpfca0
fjpfca1
3Check the WWN of each Fibre Channel card.
Execute the following command to check the WWN that corresponds to the Fibre Channel card instance
name.
# /usr/sbin/FJSVpfca/fc_info -a
"adapter=fjpfca#x" ("x" is instance number) is the format used to represent Fibre Channel card instant
names. The WWN corresponding to the instance name is displayed after "wwn=".

own_port=NL other_port=FL e_d_tov=2000ms
r_a_tov=10000ms
bb_credit=0x0 bb_frame_size=2112byte
The WWN for Fibre Channel card instance name "fjpfca0" is "100000000e248434" and WWN for
"fjpfca1" is "100000000e24846f".
4Enter the results in the "WWN" column of the "WWN instance management table for the server".
Example:
Physical slot name WWN Instance name Physical path name
/pci@4,2000/fibre-channel@1
/pci@6,4000/fibre-channel@2
fjpfca0
fjpfca1
100000000e248434
100000000e24846f
5Check the physical slot positions that correspond to the instance names.
(1) Execute the following command to check the physical slots where the Fibre Channel cards corre-
sponding to each instance name are installed. (Execute this command for all Fibre Channel
cards.)
# /usr/sbin/FJSVpfca/fc_adm -l Instance_name
For the "Instance_name", use the Fibre Channel card instance names identified in Step 1 (in this
case, "fjpfca0" and "fjpfca1").
(2) Executing the command causes the LINK and CHK LEDs of the Fibre Channel card corresponding to
the specified instance name to blink. Check the blinking LEDs.
To exit this command, press [Ctrl]+[C]. Alternatively, wait three minutes to exit automatically.

This completes the "WWN instance management table for the server".
4.2 Creating a WWN Instance Management Table for Storage
System
Create a "WWN instance management table for storage system" (provided in "Appendix A Various Manage-
ment Table Templates" (page 25)) that summarizes information relating to CA in the ETERNUS DX/AF stor-
age systems.
(Example) When there are two ports on the ETERNUS DX/AF storage systems:
Channel Adapter WWN Alias name T_ID
CM0CA0Port0
CM1CA0Port0 202000e000cb0001 203000e000cb0001 DX400_CM0CA0P0 16
16
DX400_CM1CA0P0
•Channel Adapter
CA name in the ETERNUS DX/AF storage systems
•WWN
The WWN for each CA in the ETERNUS DX/AF (check using ETERNUSmgr or ETERNUS Web GUI)
•Alias name
An arbitrarily-chosen alias name for each CA that may be used when setting up the fjpfca driver
This use of "alias name" differs from the "alias name" that is specified when setting Fibre Channel switch
zoning. However, it is recommended to set both aliases to the same name.
•T_ID (SCSI target ID)
The SCSI target ID (decimal value) that is to be defined for each CA (check using ETERNUSmgr or ETERNUS
Web GUI)
For switch connections, the SCSI target ID is irrelevant to the physical protocol, however it must be defined
as a Solaris OS SCSI driver setting. Values matched to the server environment and connection state of the
devices must be set beforehand.
It is recommended to set the same target ID to CAs that configures a multipath.

4.3 Creating a Target Binding Table
This procedure is not necessary for direct connections.
Target binding logically binds the Fibre Channel card installed in the server, and the CA on the ETERNUS
DX/AF storage systems to be connected to the server. Target binding binds the instance name of the Fibre
Channel card, channel adapter name, WWN, and target ID.
1Reflect the information from the "WWN instance management table for storage system" in the "target
binding table" (provided in "Appendix A Various Management Table Templates" (page 25)).
Target Binding Table
Channel Adapter name SCSI T-ID Alias name (WWN) Instance name
CM0CA0Port0
CM1CA0Port0 0 0DX400_CM0CA0P0
DX400_CM1CA0P0
Server name: Server#0
•Name of target server
•Each "channel adapter name" and "T_ID" entered in "4.2 Creating a WWN Instance Management Table
for Storage System" (page 12)
•The alias name entered in "4.2 Creating a WWN Instance Management Table for Storage System"
(page 12)
2Confirm the connection path(s) in the system.
Example:
Server#0
Slot0 Slot1
CA0 Port0
CM0
CA0 Port1
ETERNUS DX/AF
Fibre Channel Switch A Fibre Channel Switch B
CM1
CA0 Port1 CA0 Port0
Physical slots on Server#0 and CAs on the ETERNUS DX/AF storage systems are connected in the follow-
ing paths.
•Server#0 SLOT0 - CM0CA0
•Server#0 SLOT1 - CM1CA0

3Based on the connection path(s) confirmed in Step 2 and the information in the "WWN instance man-
agement table for the server", enter the instance names corresponding to the physical slot names on
the server into the "target binding table".
[WWN instance management table for storage system]
[target binding table]
SERV1_SLOT0
SERV1_SLOT1
100000000e248434
100000000e24846f

fjpfca1
Physical slot name WWN Instance name
0
0
CM0CA0Port0
CM1CA0Port0
DX400_CM0CA0P0
DX400_CM1CA0P0
Channel Adapter name SCSI T_ID Alias name (WWN) Instance name
fjpfca0
fjpfca1
From the two tables,
find the same
combination of
physical slot name
and Channel
Adapter as listed in
the path route table.
1. Record the instance
name in the same
row as the physical
slot name in the
target binding table.
2.
This completes the target binding table.
4.4 Setting the Configuration File (fjpfca.conf)
Edit the configuration file according to the "WWN instance management table for the server", "WWN instance
management table for storage system", and "target binding table".
For how to set to the configuration file and the setting example, refer to "Chapter 6 Required Driver Parame-
ters" (page 22).
Check the "WWN instance management table for the server", "WWN instance management table for stor-
age system", and "target binding table" for any omissions.
4.5 Re-checking the Settings
After setting is complete, check for incorrect settings in the configuration file.
1Use the "chk_conf" command to check for errors.
The settings in the configuration file can be checked for errors by entering the following command:
#/usr/sbin/FJSVpfca/chk_conf -v

If the settings are incorrect, different messages (incorrect setting examples 1 and 2) will be output.
If the "/kernel/drv/fjpfca.conf seems to be correct" message does not appear, checking the configura-
tion file settings, the status of each device, and the physical connections may find the problem.

The following items can be confirmed by executing the "chk_conf" command:
-Syntax check of general configuration file
-Detailed syntax check relating to the following properties
•alias
•port
•fcp-bind-target
•Reference relationship between fcp-bind-target and alias
•Whether or not the target device described in fcp-bind-target actually exists
2Re-check target binding setting
By using the "chk_conf" command, you can check any errors in the configuration file, and check the Fi-
bre Channel cable physical connections. However, you cannot confirm whether or not target binding
based upon the system configuration has been performed correctly using the "chk_conf" command.
Re-check the following points before restarting the server.
•Is the target binding set according to the system configuration?
•Is the target binding table recorded according to the information in the WWN instance management
table?
•Is "fjpfca.conf" set up according to the information of the target binding table?

Check the target binding values before rebooting the server. If the server boots with a setting error,
it may recognize a different storage system from that set in the system configuration, without gener-
ating a connection error.

Chapter 5
Setting Up the Server to Recognize the Logical
Units
Logical units need to be recognized with the sd driver or hddv driver.
Skip this chapter if using the ETERNUS Multipath Driver or GR Multipath Driver "grmpdautoconf" command.
5.1 Recognizing Logical Units with the sd Driver
Make the server recognize the ETERNUS DX/AF logical units using the sd driver.
First, confirm that the logical unit settings on the ETERNUS DX/AF storage systems are correct. Next, add the
descriptions of the logical units in the sd driver's configuration file (sd.conf) to register the units.
Then reboot the server to get it to recognize the logical units.
Refer to "5.2 Recognizing Logical Units with the hddv Driver" (page 21) when using the hddv driver.
5.1.1 Logical Unit Recognition
Add descriptions of the logical units to the sd driver configuration file (sd.conf) using a text editor, such as vi.
•Solaris 11 OS
If the "/etc/driver/drv/sd.conf” file does not exist, copy the "/kernel/drv/sd.conf" file to the "/etc/driver/drv"
directory and add the line to the newly copied "sd.conf" file.
If the "/etc/driver/drv/sd.conf” file exists, do not copy over the file but instead add the line to the existing
"sd.conf" file.
•Solaris 10 OS
Add the line to the "/kernel/drv/sd.conf" file.
Do not delete the lun=0 description for the system disk target ID.

The ETERNUS Web GUI or ETERNUSmgr Loop-ID is natively set as a hexadecimal value, which must be
converted to a decimal value for this setting.
•For switch connection
Set the "target=" value the same as the target ID of the "fcp-bind-target" parameter set in the configuration
file. Refer to "6.1 Setting Up the Parameters" (page 22).
5.1.2 Getting the Server to Recognize the Logical Units
The server now needs to use the new sd driver settings to recognize the logical units.
1Reconfigure and reboot the server to get it to recognize the listed logical units. Execute the following
command.
# touch /reconfigure
# /usr/sbin/shutdown -y -g0 -i6
