Chapter 3
Notes
Note the following issues when connecting the ETERNUS AF/DX to a server.
3.1 ETERNUS AF/DX Setup Notes
•Be sure to set the sub system parameters.
•Ensure that the ETERNUS AF/DX Loop-IDs are set to "Manual".
•The Loop-IDs must be unique within each FC-AL loop, and should be assigned in the ascending order.
•Do not assign 0x7D as an ETERNUS AF/DX Loop-ID.
3.2 Fibre Channel Switch Notes
The Fibre Channel switches that can be connected depend on the connection configuration that is used (the
OS and the ETERNUS AF/DX). Refer to the "Server Support Matrix for FC-SWITCH" before starting.
When a Fibre Channel switch (ETERNUS SN200 series, Brocade series) is to be used between the server and
ETERNUS AF/DX, follow the preparation-in-advance and Fibre Channel switch setup procedures given in the
"Configuration Guide -Server Connection- (Fibre Channel) Fibre Channel Switch Settings".
•Set the Fibre Channel switch domain ID, to anything other than "8".
When the domain ID is set to "8", the device cannot be recognized correctly.
•When carrying out maintenance on the Fibre Channel switches, the switch domain ID must be the same
after maintenance as it was before.
•Make certain that reconnection is made to the correct port after carrying out the maintenance of the ETER-
NUS AF/DX by using the same port number as it was used before maintenance.
•Set the link speed of the Fibre Channel switch ports according to the link speeds of the server-side Fibre
Channel cards, as follows:
Combination of devices Set the Fibre Channel switch port link
speed to...
Maximum link speed of Fibre Channel
card
Maximum link speed of Fibre Channel
switch
8Gbit/s 32Gbit/s 8Gbit/s fixed
16Gbit/s 8Gbit/s fixed
8Gbit/s 8Gbit/s fixed
4Gbit/s 4Gbit/s fixed
2Gbit/s 2Gbit/s fixed

Combination of devices Set the Fibre Channel switch port link
speed to...
Maximum link speed of Fibre Channel
card
Maximum link speed of Fibre Channel
switch
4Gbit/s 32Gbit/s —
16Gbit/s 4Gbit/s fixed

2Gbit/s 2Gbit/s fixed
2Gbit/s 32Gbit/s —
16Gbit/s —
8Gbit/s 2Gbit/s fixed
4Gbit/s 2Gbit/s fixed
2Gbit/s 2Gbit/s fixed
When connecting to a 1Gbit/s-only Fibre Channel card, the "Automatic" (default) Fibre Channel switch port
link speed must be used.
If the devices being connected together both have automatically set link speeds, the resulting link speed
may be less than optimal. The default link speed setting for Fibre Channel switch ports is "Automatic". The
link speed setting of a true HP Fibre Channel card cannot be changed to other than "Automatic", so the
Fibre Channel switch port link speeds must be fixed to match the actual speed of the server-side Fibre
Channel cards, as per the above table, so that the same link speed is always used.
•Set AD355A and AD299A Fibre Channel card connected Fibre Channel switch ports to not LinkUp via the L-
Port. This is because AD355A and AD299A Fibre Channel cards do not support PublicLoop LinkUp, and this
setting prevents them from attempting to do so.
Example:
When an AD355A is connected to switch port 4 of an ETERNUS SN200 series, execute the following com-
mand to disable LinkUp via the L-Port on port 4:
portCfgGPort 4 1
3.3 LVM Notes
•A mirrored LVM configuration using the ETERNUS AF/DX storage systems' LUNs is not recommended.
•[Bad Block Relocation] attribute must be disabled on LVM Logical volume which resides on the ETERNUS
AF/DX storage systems' LUNs.
-Example:
# lvchange -r N /dev/vg01/lvol_name
Execute this command for all logical volumes created on ETERNUS AF/DX storage systems' LUNs to disable
[Bad Block Relocation]. If [Bad Block Relocation] is not disabled, file system may be damaged.
•Raw device access to an LVM logical volume must use an I/O block size that is a multiple of 1024bytes.

3.4 HP Serviceguard Notes
"HP Serviceguard" is HP-UX cluster software. For details on how to configure an HP Serviceguard system, refer
to the relevant HP-UX manual.
3.5 HP Integrity VM Notes
Apply the settings described in this manual for a VM Host, which is an OS for operating Integrity VM.
3.6 Veritas Volume Manager (VxVM) Notes
•Confirm and acquire the ASL required for using the ETERNUS AF/DX storage systems from the following Ver-
itas web-site.
https://sort.veritas.com/asl
•Install Veritas Array Support Library (ASL) after installing VxVM.
•For VxVM 5.1 or later
ASL does not need to be installed.
3.7 Notes for Veritas Volume Manager Dynamic Multipathing
(VxVM DMP)
When using the VxVM DMP function, do not use it with a single path configuration.
3.8 Veritas Cluster Server (VCS) Notes
Veritas Cluster Server should be installed according to the directions given in the documentation provided
with Veritas Cluster Server.
3.9 Server Startup and Power Supply Control Notes
Before turning the server on, check that the ETERNUS AF/DX 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 AF/DX storage systems.
Also, when the ETERNUS AF/DX power supply is being controlled by a connected server, make sure that the
ETERNUS AF/DX 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 run-
ning server cannot be saved to the ETERNUS AF/DX storage systems, and already saved data may also be
affected.

Chapter 4
Checking the Server Information
Check the World Wide Name (WWN).
When using the "Security" function (Affinity Mode) of the ETERNUS AF/DX storage systems, it is necessary to
specify the WWN of the Fibre Channel card. Use the "fcmsutil" command to specify the device file of the Fibre
Channel card, and the WWN of the Fibre Channel card can be checked.
A WWN is not required if the "Host Affinity" function is not used.
1Use the "ioscan" command to check the Fibre Channel card device files.
# ioscan -funC fc
The format of the device file name will vary according to the Fibre Channel cards being used.
In the following example, the recognized Fibre Channel card's device files are "/dev/fcd0", "/dev/fcd1",
"/dev/fcd2", and "/dev/fcd3".
# ioscan -funC fc

Installing Drivers and Setting Up the Server
7.1 Installing the Driver
Install the necessary drivers and patches following the Fibre Channel card installation guide.
7.2 Setting Up the Server
The server control environment now needs to be set up.
Set the command queue depth and the maximum number of volume groups for the server environment.
7.2.1 Setting Up the Command Queue Depth
Set the number of commands allowed to be queued (command queue depth) on each LUN in the ETERNUS
AF/DX storage systems from the Fibre Channel card. This setting optimizes the connection between the ETER-
NUS AF/DX storage systems and the server.
Model Setting value
Command queue depth
ETERNUS AF/DX Arbitrary (*1)
*1: Recommended value = (maximum number of simultaneous command processes per CA port) ¸ (num-
ber of Fibre Channel ports connected to a single CA port) ¸ (number of LUNs)
(Round the result down to the nearest whole number)
•The maximum number of simultaneous command processes per CA port is as follows:
The value is used by multiple servers that share the CA port. The commands are processed until the
limit is reached.
Model Maximum number of simultaneous command processes

For connection schemes in which an ETERNUS AF/DX FC port is shared by multiple servers, the command
queue depth is again determined by the number of LUNs recognized by each server on the single path. In
this example, "51" is set as the command queue depth for server A and "42" for server B.

For multipath connection, the command queue depth is determined similarly.
For the multipath connection example shown below, 20 LUNs are recognized on each path, so the command
queue depth is set to "51". For all types of multipath, the command queue depth is always decided by the
number of LUNs recognized on each individual path.

Command queue depth setting procedure depends on the HP-UX version:
•For HP-UX11iv3
Set the command queue depth using the LU property "max_q_depth". The "max_q_depth" is set using the
"scsimgr" command.
-Example:
Setting the command queue depth of disk20 to 8
# scsimgr save_attr -D /dev/rdisk/disk20 -a max_q_depth=8
Refer to the HP-UX manuals for details of the "scsimgr" command.
