Chapter 3 Notes Note the following issues when performing the relevant operation. 3.1 Connection Notes 3.1.1 SCSI Devices and Linux The ETERNUS DX Disk storage systems represented to the server as set of Fibre Channel connected SCSI disks. The server then handles the ETERNUS DX Disk storage systems’ disks as LUN (logical units). Under Linux, SCSI disk devices have the following definitions in "/dev": Device (LUN) Partition sda sdb sda1, sda2,. . . . sda15 sdb1, sdb2,. . . .
Chapter 3 Notes > 3.2 Fibre Channel Card Notes 3.2 Fibre Channel Card Notes 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.
Chapter 3 Notes > 3.5 Design Sheet Notes 3.5 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. 3.
Chapter 3 Notes > 3.7 VERITAS Cluster Server (VCS) Notes 3.7 VERITAS Cluster Server (VCS) Notes • Installing VERITAS Cluster Server VERITAS Cluster Server should be installed according to the directions given in the documentation provided with VERITAS Cluster Server. 3.
Chapter 4 Installing and Setting Up the 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".
Chapter 5 Setting Up the ETERNUS DX Disk Storage Systems Set up the ETERNUS DX Disk storage systems using Web GUI or ETERNUSmgr. ETERNUS DX Disk storage systems' setup can be performed independently of server setup.
Chapter 6 Setting the Fibre Channel Switches This chapter describes about the required settings for connecting ETERNUS DX Disk storage system via Fibre Channel switches. Set the Fibre Channel switches according to "ETERNUS DX Disk storage systems Server Connection Guide (Fibre Channel) Fibre Channel Switch Settings". 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.
Chapter 7 Installing and Setting Up the Drivers Install the Fibre Channel Card driver, and set up the server environment. Refer to each "ETERNUS DX Disk storage systems Server Connection Guide (Fibre Channel) for Linux Driver Settings" for detailed setting procedures.
Chapter 8 Connecting the Server to the ETERNUS DX Disk Storage Systems After all the required drivers have been installed, shut down the OS and make sure the server is turned off. Connect the shutdown server to the ETERNUS DX Disk storage systems using Fibre Channel cables, then restart the OS. The server and ETERNUS DX Disk storage systems must be connected for the procedures that follow.
Chapter 9 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.
Chapter 9 Logical Unit Recognition > 9.1 Displaying the Recognized Logical Units • "dmesg" command for LUN display Use the "dmesg" command in order to confirm whether Linux has recognized the LUNs in the ETERNUS DX Disk storage systems. The following shows an example: #dmemsg|less : Emulex LightPulse FC SCSI/IP 4.21q PCI:Found IRQ 10 for device 03:06.0 !lpfc0:031:Link Up Event received Data:1 1 1 2 PCI:Found IRQ 5 for device 04:02.0 IRQ routing conflict for 04:02.
Chapter 9 Logical Unit Recognition > 9.1 Displaying the Recognized Logical Units 9.1.2 For SUSE Linux Enterprise Server • Checking for LUNs in the boot message Open the /var/log/boot.msg file to confirm that Linux has recognized the ETERNUS DX Disk storage systems' LUNs. The following shows an example (Messages can be scrolled (back and forth) using the arrow keys).
Chapter 10 Setting Up and Checking the Multipath Driver 10.1 ETERNUS Multipath Driver or GR Multipath Driver Refer to either the "ETERNUS Multipath Driver" or "GR Multipath Driver" manual (as applicable) for the setup and confirmation procedures. 10.2 device-mapper multipath Set up and confirm the device mapper multipaths. Refer to the "ETERNUS DX Disk storage systems Server Connection Guide (Fibre Channel) for Linux device-mapper multipath" for the setup and confirmation procedures.
Chapter 11 Setting Up the File System 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.
Appendix A Restoration Procedure for when a Path Degrades in a VERITAS Volume Manager Environment > 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.
Appendix A Restoration Procedure for when a Path Degrades in a VERITAS Volume Manager Environment > 4 Check the volume status. Check that the status of a volume that was "DISABLED" in Step 1-2 is changed to "ENABLED".
