Chapter 3 Notes
Note the following issues when performing the relevant operation.
3.1 SAS Card Notes
Check the BIOS and firmware versions for the SAS cards being used. If these are different from
the versions in the "Server Support Matrix", download and install the appropriate BIOS or firm-
ware version from the SAS card vendor's web-site.
3.2 Server Startup and Power Supply Control Notes
Before turning the server on, check that the ETERNUS Disk storage systems 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 connected
server, make sure that the ETERNUS Disk storage system does not shut down before the con-
nected servers.
If turned off, data writes from the running server cannot be saved to the ETERNUS Disk storage
systems, and already saved data may also be affected.
3.3 RHEL Notes
For details involving RHEL, refer to the Red Hat web-site and any documentation available.
3.4 SLES Notes
For details involving SLES, refer to the Novell web-site and any documentation available.

Chapter 4 Installing and Setting Up ETERNUSmgr
If ETERNUSmgr is to be used, install it according to the directions given in the "ETERNUSmgr
Install Guide". After the installation, set up ETERNUSmgr following the instructions in the
"ETERNUSmgr User Guide".

Systems
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 "ETERNUS2000 Disk storage systems
Server Connection Guide (SAS) ETERNUS Disk Storage System Settings" and "ETERNUSmgr
User Guide".

6.1 For Fujitsu SAS Cards
Refer to the documentation provided with the SAS card for the SAS card driver installation proce-
dure.
6.2 For LSI Logic SAS Cards
The SAS card driver does not need to be installed because it is one of the OS default drivers.

Chapter 8 LUN Recognition
8.1 Making the Server Recognize the LUNs
The following procedure is used to get the server to recognize the ETERNUS Disk storage sys-
tem LUNs.
Procedure
1When the driver installation process is complete, shut down the OS and turn the
server power off.
2Turn the ETERNUS Disk storage system power off.
3Use the SAS cables to connect the Linux server to the ETERNUS Disk storage
system.
4Turn the ETERNUS Disk storage system back on.
5Turn the server power back on and boot the OS.
Check that the Linux server recognizes the ETERNUS Disk storage system LUNs.
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 Disk storage
systems' LUNs. Example: If there is one internal SCSI disk, it is assigned a SCSI device
name as follows:
End of procedure
SCSI device name by-id name (Example) Explanation
/dev/sda /dev/disk/by-id/scsi-
36003005700026cc011251e4b0b80ac59 Internal SCSI disk

P3AM-4212-02ENZ0
8.2 Displaying the Recognized Logical Units
The driver version and information of each LUN's SCSI device name, etc. are displayed in the
console message when Linux is booted up. Although this console message disappears soon
from the screen, it can be re-displayed using the following command:
8.2.1 For Red Hat Enterprise Linux
The driver version and information of each LUN's SCSI device name, etc. are displayed in the
console message when Linux is booted up. Although this console message disappears soon
from the screen, it can be re-displayed using the following command:
•"dmesg" command for LUN display
Use the "dmesg" command in order to confirm whether Linux has recognized the LUNs in the
ETERNUS Disk storage systems.
The following shows an example:
•"cat" command for LUN display
Use the "cat" command to display the "/proc/scsi/scsi" file, where you can confirm the
recognized 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 for
each connected LUN (i.e. if there are 3 LUNs, 6 SCSI devices are shown).
