Perform the folowing steps to install Subsystem Device Driver 1. Configure the ESS and SAN environment. 2. Obtain the World Wide name of the Qlogic HBA you are going to boot from (the second HBA will not be configured at this time). This can be obtained by entering the Qlogic BIOS through CRTL+Q in the Adapter Setting Panel. 3. Boot the server you are setting up boot support for. Make sure there is only 1 path from your QLogic HBA to ESS storage. Hit CTRL-Q to enter the QLOGIC BIOS Fast Utility. 4. Select the boot support HBA. Select Configuration Settings. 5. Under the Host Adapter Setting Panel, Enable the BIOS for the adapter. 6. Under the Selectable Boot Settings panel, enable Selectable Boot. Select the first (primary) boot and hit Enter. Choose IBM device and hit Enter. 7. At Select LUN, choose first supported LUN, which is LUN 0. 8. Save changes and reboot system with bootable Windows Server 2003 Enterprise Edition CD. 9. At very first Windows 2003 installation screen, hit F6 to install third party device. 10. Choose S to specify additional device. Insert floppy disk contains Qlogic HBA driver and hit Enter. 11. Continue install Windows 2003 as normal. Select first ESS volume seen by Qlogic HBA as the device to install Windows 2003 on it. 12. Install Windows Server 2003 Service Pack if applicable. 13. Install SDD and reboot. You may be asked by the system to reboot 1 more time. 14. Shut down the system. Connect FC cables from other Qlogic HBA to ESS storage. Make sure BIOS of this adapter is Disable. Add multi-paths to ESS. Restart the system. 3.3.1.2 Booting from ESS device with Windows server 2003/64-bit and Subsystem Device Driver 1.5.1.2 using Qlogic HBA Perform the folowing steps to install Subsystem Device Driver 1) Load EFI code v1.07 into Qlogic HBA flash. Build the Qlogic EFI Code into CD using the iso file. Insert EFI Code CD in CD-Rom. At EFI prompt, Enter the following commands: fs0 flasutil After some time, the flash utility will start. It displays the addresses of all available Qlogic adapters. Choose address of each HBA and select f option to load code into flash memory 2) Enable boot option in Qlogic EFI Configuration. At EFI Shell, enter drivers -b A list of installed EFI drivers is displayed. Find driver with name QlcFC SCSI PASS Thru Driver. Find DRVNUM of that driver. Enter DrvCfg DRVNUM List of adapters under this driver is displayed. Each HBA has its own CTRLNUM For each of HBAs that need to configure boot option, enter Drvcfg -s DRVNUM CTRLNUM At QLcConfig> prompt, enter b to enable boot option c for connection option, and d to display storage backend WWN. Topology should be point-to-point. Exit EFI environment and reboot the system. 3) Connect USB floppy drive to the system. Insert floppy disk that contains ramdisk.efi file. This file can be obtained from Intel Application Tool Kit under binaries\sal64. Please see http://www.intel.com/technology/efi/index.html USB drive should be attached to fs0. Enter following command: fs0: load ramdisk.efi This will create virtual storage. Do map -r to refresh 4) Insert floppy disk that contains Qlogic driver for your QLA HBAs. Assume fs0 is virtual storage and fs1 is the USB drive. You can do map -b to find out fs0: copy fs1:\*.* This will copy Qlogic driver into the virtual storage. 5) Install W2003 64 bit OS onto SAN device. Procedure should be same as for 32 bit OS. When asked to hit S to Specify additional driver of HBA, skip this step to use the Qlogic driver loaded from virtual storage 6) After finish installing the OS, install SDD, and add multipaths 3.3.2 Allow disabling/enabling sddsrv tcpip port (ref CMVC 58218) Until SDD 1.5.0.X release, sddsrv by default was binding to tcpip port and listening for incoming requests. Starting from SDD 1.5.1.2 release we are providing a way to dynamically enable and disable the port binding for sddsrv. We are shipping sddsrv.conf file with the package which contains parameters to enable the port binding. By default sddsrv will not bind to any tcpip port. Sddsrv.conf file contains following parameters: 1. enableport - This parameter allows user to enable or disable sddsrv to bind to tcpip port. Default value of this parameter is set to false. User can set this parameter to true if he wants to enable the tcpip interface of sddsrv. 2. loopbackbind - If user sets enableport parameter to true, then this parameter specifies if sddsrv will listen to any Internet address or the loopback (127.0.01) address. To enable sddsrv to listen to any Internet address, this parameter must be set to false. If enableport parameter is set to false, this parameter will not have any effect. 3. portnumber - This parameter specifies the portnumber on which sddsrv will bind to. Default value of this parameter is 20001. User can modify this parameter to change the portnumber. If enableport parameter is set to true, then this parameter must be set to valid port number on which sddsrv can bind upon. Please use the port number which is not used by any other application. User can modify any of this parameters anytime while sddsrv is running and thus can enable or disable tcpip interface dynamically. Also since sddsrv tcpip interface by default is disabled, SDD provides a way to get the sddsrv trace. You will find sddsrv.log and sddsrv_bak.log files in \%windir%\system32\directory. These are wrapped around files and each are 4 MB in size at MAX. User should ensure there is at least 8 megabyte disk space available on system driver(the drive where Windows is installed). 3.3.3 Enhance SDD first time data capture (ref CMVC 59562) SDD driver code and sddsrv code have been changed to collect SDD trace periodically and write the data to the system local hard drive. Sddsrv will maintain two 4MB trace files on the hard drive, namely sdd.log and sdd_bak.log. These trace files are placed under \%windir%\system32\. Plus the space requirement for sddsrv, User should ensure there is at least 16 megabyte disk space available on system driver(the drive where Windows is installed). =============================================================================== 3.4 Known Issues 1. "datapath query wwpn" doesn't work in Windows Server 2003(64bit) with Emulex driver/HBA. ================================================================================= 3.5 Known issues and workaround details Note: User may notice many Windows Server 2003 pop-ups when installing a SDD version that does not have a digital signature or test signature. The pop-up will be displayed by the Hardware Wizard the first time LUNs being discovered. ------------------------------------------------------------------------------- 4.0 User license agreement for IBM device drivers NOTICE: PLEASE READ THIS AGREEMENT CAREFULLY BEFORE USING THE PROGRAM AND DOCUMENTATION.
