When a Fibre Channel card is installed in the server after installation of the OS, it should be automatically recognized the next time the OS is restarted. Proceed as follows:
• Red Hat Enterprise Linux
The kudzu starts automatically during the system reboot. Select "Ignore".
• SUSE Linux Enterprise Server
The "New hardware detection" window appears during the system reboot. Select "No".
3.3
Fibre Channel Switch Notes
• When using a Fibre Channel switch (ETERNUS SN200 series, Brocade DCX series) between
the server and ETERNUS DX Disk storage systems, it is necessary to prepare and set the
Fibre Channel switch in advance. When using a Fibre Channel switch (ETERNUS SN200
series, Brocade DCX series), be sure to read the "ETERNUS DX Disk storage systems
Server Connection Guide (Fibre Channel) Fibre Channel Switch Settings".
• When 4Gbit/s QLogic Fibre Channel cards are connected to the ETERNUS SN200 series or
Brocade DCX series via Fibre Channel switch, and the SFP produces an incorrect linkup,
change the Fibre Channel card BIOS settings. Contact your maintenance engineer for SFP
details.
3.4
Server Startup and Power Supply Control Notes
Before turning the server on, check that the ETERNUS DX Disk storage systems and Fibre
Channel switches are all "Ready". If the server is turned on and they are not "Ready", the server
will not be able to recognize the ETERNUS DX Disk storage systems.
Also, when the ETERNUS DX Disk storage system power supply is being controlled by a connected server, make sure that the ETERNUS DX Disk storage system does not shut down
before the connected servers. Similarly, the Fibre Channel switches must also be turned off after
the connected servers have been shut down.
If turned off, data writes from the running server cannot be saved to the ETERNUS DX Disk storage systems, and already saved data may also be affected.

Design Sheet Notes
The design sheet is a spreadsheet program work sheet that is used to simplify the process of
installing the ETERNUS DX Disk storage systems.
It is important to save the current environment after first installing the system and also after each
post installation system modification, addition, or maintenance operation. Creating a design
sheet makes installation and maintenance of the system easy.

VERITAS Volume Manager (VxVM) Notes
• Install VERITAS Array Support Library (ASL) after installing VxVM.
• Installing VxVM
VxVM should be installed as specified in its accompanying documentation.
• When using VxVM 5.0
If the ETERNUS DX Disk storage systems are connected to a configuration that uses the
VxVM, the VERITAS Array Support Library (ASL) will also need to be installed.
Which version of VERITAS ASL is required will depend on the storage system and version of
VxVM used. Download the VERITAS ASL version that matches your environment from the
following Symantec web-site.
Refer to the Symantec web-site for VERITAS ASL installation details.

• If a path degrades when VERITAS Volume Manager is used, some volumes may not be successfully recognized after path restoration regardless of the Linux version or VxVM version
that is installed.
In this case, volume recognition is required after restoring the LUN using the utility provided
by each Fibre Channel card vendor. Refer to "Appendix A Restoration Procedure for when a
Path Degrades in a VERITAS Volume Manager Environment" (page 35) for more details.

Notes on Connecting the ETERNUS DX Disk Storage
System to a Server
When connecting the ETERNUS DX Disk storage system to a server using a Fibre Channel
cable, make sure to confirm that all the settings on the ETERNUS DX Disk storage system are
complete. The WWN Automatic Acquisition function should not be used because it requires the
server to be connected.
Otherwise, LUNs in the ETERNUS DX Disk storage system may not be recognized properly.

Logical Unit Recognition
At boot up, Linux automatically recognizes all SCSI disks and assigns them successive device
names starting from "sda". When assigning the device names, any internal SCSI disks are
assigned first, followed by the assignment of the ETERNUS DX Disk storage systems' LUNs.
Example: If there is one internal SCSI disk, it is assigned a SCSI device name as follows:
9.1
SCSI device name
by-id name (Example)

After Linux has recognized the ETERNUS DX Disk storage systems' LUNs, access for data storage will be possible after completing the following steps:
• Setting up Partitions
• Formatting Partitions
• Mounting Partitions
If by-id names are being used with Red Hat Enterprise Linux AS v.4 Update
4 or Red Hat Enterprise Linux ES v.4 Update 4 or later, then the accessible
device names will be by-id names.

Appendix A
Restoration Procedure for when a Path Degrades
in a VERITAS Volume Manager Environment
If a path degrades when VERITAS Volume Manager is used, some volumes may not be recognized properly after path restoration.
In this case, volume recognition is required after restoring LUN recognition using the Change
LUN State Utility provided by each Fibre Channel card vendor.
Procedure
1
Check the Fibre Channel card's controller number and status.
Use the "vxdmpadm" command to check the controller number and controller status of the
Fibre Channel card that corresponds to the unrecognized volume.
1-1 Check the controller number of the Fibre Channel card in which there is a path
connected to the ETERNUS DX Disk storage system.
# vxdmpadm listctlr all
Example (for ETERNUS DX410)
# vxdmpadm listctlr all

In this example, the controller numbers of the Fibre Channel cards connected to the
ETERNUS DX410 are "c6" and "c7".

1-2 Check the status of volume paths connected to each Fibre Channel card using the
controller numbers that were checked in Step 1-1.
In this step, check the controller number corresponding to the volume for which
"DISABLED" is displayed.

In this example, "DISABLED" is displayed for the "sde" volume.
The controller number of the Fibre Channel card in which the volume cannot be recognized is "c7".
2
Obtain and apply the Change LUN State Utility.
2-1 Obtain the Change LUN State Utility provided by each Fibre Channel card vendor.
- For QLogic Fibre Channel cards
Obtain the Change LUN State Utility from the QLogic web-site
(http://www.qlogic.com/).
- For Emulex Fibre Channel cards
Obtain the Change LUN State Utility from the Emulex web-site
(http://www.emulex.com/).
Refer to each vendor web-site for details about the Change LUN State Utility.
2-2 Apply the Change LUN State Utility that is obtained in Step 2-1 according to the procedure specified by each vendor to change the state of the LUN to recognized.
Refer to each vendor web-site for details about how to apply the Change LUN State
Utility.
3
Enable VERITAS Volume Manager.
Enable VERITAS Volume Manager using the "vxdctl" command.
# vxdctl enable
