Chapter 3
Notes
Note the following issues when connecting the ETERNUS DX/AF to a server.
3.1 Installation Notes
To ensure reliable access to ETERNUS DX/AF storage systems, multipath configuration is recommended.
•
Setting up multiple access paths between the server and the ETERNUS DX/AF storage systems, then using
•
the XenServer multipath, provides improved access redundancy.
Enable the virtualization support functions (Intel VT or AMD-V) of the server before installing XenServer.
•
For details on the settings, refer to the relevant manual of the server to be used.
Install XenServer when the ETERNUS DX/AF is not connected to the server.
•
The ETERNUS Multipath Driver does not need to be installed on the XenServer Virtual Machine. The Xen-
•
Server multipath provides path redundancy.
When multiple paths are used, a multipath driver must be set. If a multipath driver is not set, the XenServ-
•
er multipath does not perform proper load balancing for the ETERNUS DX/AF.
Before setting a multipath configuration, create Storage Repositories for all the LUNs that exist in the
•
ETERNUS DX/AF.
3.2 Operating Notes
If a path error occurs in a multipath configuration using XenServer, the status of the failed multipath may
•
not be displayed. The status is displayed again when the failed path recovers.
When XenServer is managed and operated with XenCenter, multipath errors may not be detected properly
•
by XenCenter. When checking multipath status, also check the status on the XenServer host side.
3.3 ETERNUS DX/AF Setup Notes
Host Response must be set before the ETERNUS DX/AF is connected to the XenServer host.
•
Even if the Eco-mode of the ETERNUS DX/AF is enabled for a multipath configuration with XenServer, disk
•
motors may not stop according to the Eco-mode settings.

Chapter 3 Notes
3.4 Server Startup and Power Supply Control Notes
3.4 Server Startup and Power Supply Control Notes
Before turning the server on, check that the ETERNUS DX/AF 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/AF storage systems.
Also, when the ETERNUS DX/AF power supply is being controlled by a connected server, make sure that the
ETERNUS DX/AF 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/AF storage systems, and already saved data may also be
affected.

Chapter 4
Checking Fibre Channel Card Information
The WWNs of Fibre Channel cards are necessary when a system error occurs, when server access to the ETERNUS DX/AF is limited (such as when using the Host Affinity function), or when the ETERNUS DX/AF is connected to the server via Fibre Channel switches.
Use the methods described in the following examples to obtain the WWN information of the Fibre Channel
card to be used.
Example 1:
Check the WWN using the utilities that are provided by the Fibre Channel card vendors.
Emulex: LightPulse BIOS Utility
QLogic: Fast!UTIL
Example 2:
When XenServer is already installed, a WWN can be checked using the following tools that are installed in
XenServer.
Emulex: OneCommand Manager Command Line Interface (XenServer 5.6 or later)
HBAnyware Command Line Interface (XenServer 5.5)
QLogic: SANsurfer FC HBA CLI (XenServer earlier than 6.5)
QConvergeConsole CLI (XenServer 5.6 or later)

8.2 Turning On the Devices
Setting Up XenServer
The setting value for X depends on the ETERNUS DX/AF model. Refer to the following tables.
Driver parameter Setting value
ql2xmaxqdepth Arbitrary (*1)
*1: Recommended value = 1024 ¸ (number of Fibre Channel ports that are connected to a single CA
Example (when "8" is set for "ql2xmaxqdepth")
(Up to 1024 for each FC port of the ETERNUS DX/AF)
port) ¸ number of LUNs
(Round the result down)
• Use the value of "8" if the actual result is lower. Use the maximum value if the actual result ex-
ceeds the maximum value for the driver.
• To achieve maximum system performance, this value can be changed according to the server
load and the peak operating times.
• The number of simultaneous command executions per CA port for the ETERNUS DX/AF is limited
to 1024. This value is used by multiple servers that share the CA port. A maximum of 1024 commands can be executed per CA port.
options qla2xxx ql2xmaxqdepth=8
• After the driver parameter settings are complete for XenServer 7.0, create an initial RAM disk.
Create an initial RAM disk image file to match the kernel being used. Refer to the QLogic Fibre
Channel card manual for details on the creation method.
• Creating an initial RAM disk is not required for XenServer 7.1 and later.
3 Shut down the server.
After the driver parameter settings are complete, shut down the XenServer host, and then connect the
ETERNUS DX/AF to the XenServer host with cables.
8.2 Turning On the Devices
To turn on the connected devices, use the following procedure:
1 Turn on the Fibre Channel switch power (if used).
2 Check that the Ready LED (or equivalent) is lit on the Fibre Channel switch.
3 Turn on the ETERNUS DX/AF.

Check that the number of recognized LUNs is correct.
The SCSI disks for the number of connected LUNs
for each path are recognized. (In this example,
four SCSI disks are recognized since there are
two LUNs in the two-path configuration.)
Check that the connected
ETERNUS DX/AF model
is correct.
For a multipath configuration,
check that the same number of LUNs is
recognized for each path.
