Chapter 3 Notes

P

Note the following issues when performing the relevant operation.

3.1 Connection Notes

3.1.1 SCSI Devices and Linux

The ETERNUS Disk storage systems are recognized by the server as a set of Fibre Channelconnected SCSI disks. The server then recognizes the ETERNUS Disk storage systems’ disksas LUN (logical units). For Linux, SCSI disk devices have the following definitions in "/dev":

3.2 Converged Network Adapter Card Notes

When a Converged Network Adapter card is installed in the server after installation of the OS, itshould be automatically recognized the next time the OS is restarted. Proceed as follows when aresponse is requested:

• Red Hat Enterprise LinuxThe kudzu starts automatically during the system reboot. Select "Ignore".

• SUSE Linux Enterprise ServerThe "New hardware detection" window appears during the system reboot. Select "No".

Chapter 3 Notes > 3.3 Fibre Channel Switch and CEE/FCoE Switch Notes

P

3.3 Fibre Channel Switch and CEE/FCoE Switch Notes

When using a Fibre Channel switch and a CEE/FCoE switch between the server and ETERNUSDisk storage systems, it is necessary to prepare and set the Fibre Channel switch and the CEE/FCoE switch in advance. When using a Fibre Channel switch and a CEE/FCoE switch, be sureto read the "ETERNUS Disk storage systems Server Connection Guide (Fibre Channel) FibreChannel Switch Settings" or "Converged Enhanced Ethernet Administrator’s Guide" and "FabricOS Administrator’s Guide".

3.4 Server Startup and Power Supply Control Notes

Before turning the server on, check that the ETERNUS Disk storage systems, Fibre Channelswitches, and CEE/FCoE 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 Disk storage systems.Also, when the ETERNUS Disk storage system power supply is being controlled by a connectedserver, make sure that the ETERNUS Disk storage system does not shut down before the con-nected servers. Similarly, the Fibre Channel switches and the CEE/FCoE switches must also beturned off after the connected servers have been shut down. If turned off, data writes from the running server cannot be saved to the ETERNUS Disk storagesystems, and already saved data may also be affected.

3.5 Design Sheet Notes

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

3.6 Notes on Connecting the ETERNUS Disk Storage System to a Server

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

Chapter 4 Installing and Setting Up the ETERNUSmgr

P

If ETERNUSmgr is to be used, install it according to the directions given in the "ETERNUSmgrInstall Guide". After the installation, set up ETERNUSmgr following the instructions in the "ETER-NUSmgr User Guide".



3AM-4712-01ENZ0

Chapter 5 Setting Up the ETERNUS Disk Storage Systems

P

Set up the ETERNUS Disk storage systems using ETERNUSmgr.

ETERNUS Disk storage systems' setup can be performed independently of server setup.For details on how to perform these settings, refer to the "ETERNUS Disk storage systemsServer Connection Guide (Fibre Channel) ETERNUS Disk Storage System Settings" and"ETERNUSmgr User Guide".

Chapter 6 Setting the Fibre Channel Switches and the CEE/FCoE Switches

P

This chapter describes about the required settings for connecting ETERNUS Disk storagesystem via Fibre Channel switches and CEE/FCoE switches.

Set the Fibre Channel switches and the CEE/FCoE switches according to "ETERNUS Diskstorage systems Server Connection Guide (Fibre Channel) Fibre Channel Switch Settings" or"Converged Enhanced Ethernet Administrator’s Guide" and "Fabric OS Administrator’s Guide".

When setting the access path using the ETERNUS SF Storage Cruiser,Host Response No. will be set to default values.Set the Host Response No. after setting the access path using theETERNUS SF Storage Cruiser.

Chapter 8 Connecting the Server to the ETERNUS Disk Storage Systems

P

After all the required drivers have been installed, shut down the OS and make sure the server isturned off.Connect the shutdown server to the ETERNUS Disk storage systems using Fibre Channelcables, then restart the OS.The server and ETERNUS Disk storage systems must be connected for the procedures that fol-low.

Chapter 9 Logical Unit Recognition

P

At boot up, Linux automatically recognizes all SCSI disks and assigns them successive devicenames starting from "sda". When assigning the device names, any internal SCSI disks areassigned first, followed by the assignment of the ETERNUS Disk storage systems' LUNs. Exam-ple: If there is one internal SCSI disk, it is assigned a SCSI device name as follows:

9.1 Displaying the Recognized Logical Units

The driver version and information of each LUN's SCSI device name, etc. are displayed in theconsole message when Linux is booted up. Although this console message disappears soonfrom the screen, it can be re-displayed using the following command:

9.1.1 For Red Hat Enterprise Linux

The driver version and information of each LUN's SCSI device name, etc. are displayed in theconsole message when Linux is booted up. Although this console message disappears soonfrom the screen, it can be re-displayed using the following command:

• "dmesg" command for LUN displayUse the "dmesg" command in order to confirm whether Linux has recognized the LUNs in theETERNUS Disk storage systems.The following shows an example:

• "cat" command for LUN displayUse the "cat" command to display the "/proc/scsi/scsi" file, where you can confirm therecognized SCSI devices.The following shows an example of this.

At this point the Multipath Driver has not been set up yet, so two SCSI devices are shown foreach connected LUN (i.e. if there are 3 LUNs, 6 SCSI devices are shown).
