Refer to the documentation that came with your CD-ROM writer for details on how to create a CD from an ISO image. If a CD writer is not available and the CD is lost, defective, or destroyed, contact the IBM HelpCenter for a replacement "IBM ServeRAID Support" CD. 2.0 Change History __________________ 2.1 ServeRAID Family 4.70 to 4.80 __________________________________ o Support for new operating systems: + Caldera OpenLinux 3.1 + Caldera Open UNIX 8.0 + Microsoft Windows XP Professional + Novell NetWare 6.0 + SuSE Linux 7.1 + Turbolinux 6.5 o A new Configuration wizard for ServeRAID configuration that provides an easier-to-use interface, better access to status indicators, and enhanced functionality that eliminates potential configurations that are not valid. o New and expanded context-sensitive online assistance that is displayed within the ServeRAID Manager interface rather than in a separate window. o Reporting of physical drive field replaceable unit (FRU) information within events. IBM service representatives use the FRU information to identify the physical drive model replacement without opening the server cover. o Enhanced functionality in the ServeRAID Manager to include accessibility features and functions so that the Manager is directly accessible without regard to the ability of the user. o Enhanced functionality in the ServeRAID Manager to establish a compatibility baseline, so that future releases will be able to connect and manage this release. o Added ability to set online physical drives to the defunct state. o Fixed problem with data coming from the serial port when using the IBM ServeRAID Support CD. o Fixed problem when starting the "IBM ServeRAID Support" CD and an Adaptec 29160 is installed in a higher priority 32-bit PCI slot than the ServeRAID controller. o Fixed problem with controller timeouts when writing large sequential blocks of data, such as a database initialization. o Fixed spurious interrupts on SCO OpenServer. o Fixed problem when configuring for a cluster where user could enter more than 12 characters for the controller names. The maximum length for controller names is 12 characters. o Fixed intermittent problem where hot-swap rebuild did not start. o Fixed problem in NetWare 5.1 when issuing IPSSEND CREATE on ServeRAID-3 controllers. Output displays an error message that says: "Could not send the command to the controller." 2.2 ServeRAID Family 4.50 to 4.70 __________________________________ o Support for the new IBM ServeRAID-4Mx Ultra160 SCSI controller and the IBM ServeRAID-4Lx Ultra160 SCSI controller. o Fixed problem with hard disk drives that were intermittently marked defunct in IBM xSeries 240 servers that were installed with a pair of ServeRAID controllers that were: o Configured for failover AND o Both installed in hot-swap PCI slots. o Fixed problem with FlashCopy that caused systems with heavy input/output (I/O) activities to hang. If a logical drive was undergoing both of the following: o Extremely heavy system I/O activities o A FlashCopy operation the ServeRAID controller resources were significantly reduced. When controller resources are scarce, the following can occur: o The ServeRAID controller resets o The system hangs. o Fixed problem that occurred when installing the IBM ServeRAID Cluster Solution. The IBM ServeRAID Windows NT Cluster Solution program (the cluster wizard) did not detect IPS shared resource. o Fixed problem where, during disk-stress testing, the ServeRAID-4M controller installed in an IBM OS/2 system stopped responding. o In a TPC-C benchmark cluster, IBM ServeRAID software version 4.30.04 outperformed version 4.70 by 4%. When the maximum number of flushes is set to either 12 or 16 for TPC-C for 64 KB stripe-unit size, the performance will improve to the normal range. For more information about TPC-C, visit the following address: http://www.tpc.org/information/benchmarks.asp o The time stamp function that was introduced in Microsoft Windows NT 4.0 has been fixed. o Removed call to the unsupported ZwOpenKey function during crash dump. o Fixed intermittent problem associated with synchronizing a logical drive after importing spanned arrays. o Fixed problem where, after restoring the ServeRAID controller to the factory-default settings, the hard disk drive light remained on. o Improved rebuild time when background input/output (I/O) is in progress. o Improved recovery from 0311 unrecoverable storage disk media errors. o For Microsoft Windows NT 4.0, fixed problems where, when called during a crash dump, the scsiportgetbusdata function returned bad data. o Fixed problem where, after completing multiple hot-add operations to add ServeRAID controllers to the server, one or more of the ServeRAID controllers might stop responding. o For Microsoft Windows 2000 installed on xSeries 370 or Netfinity 8500R servers, fixed intermittent blue screen on servers with more than 4 GB of RAM installed. o For Microsoft Windows 2000, fixed blue screen that occurred after disabling any of the ServeRAID device drivers. o For Microsoft Windows 2000, when the ServeRAID failover device driver is installed, Windows 2000 might fail to recognize the physical drives attached to other SCSI controllers. o Removed the feature that determines the friendly slot number. This feature is unreliable when using Microsoft Windows 2000. o The IBM Hot Plug for Windows NT 4.0 Package (version 4.2) has added support for the ServeRAID-4M, ServeRAID-4Mx, ServeRAID-4L, and ServeRAID-4Lx controllers. Download this software from the IBM Support Web site at http://www.ibm.com/pc/support. o Fixed problem where the IPSSEND SYNCH command would stop at 99%. This problem occurred when a logical drive was undergoing a synchronization operation and the logical drive contained a bad stripe. 2.3 ServeRAID Family 4.40 to 4.50 __________________________________ o Support for OS/2 SMP and OS/2 e-business. o Added support for uninstalling the IBM ServeRAID Failover Virtual Adapter in Windows 2000. o Fixed the BIOS error reporting function to the service processor. o Fixed intermittent failure during startup of Windows NT. Previously, a blue screen occurred after loss of power to the server. o Fixed failure to rebuild hot-spare physical drive. 2.4 ServeRAID Family 4.30 to 4.40 __________________________________ o Fixed ServeRAID problem associated with loading (booting) from a SCSI CD-ROM drive. This problem affected only ServeRAID-3, ServeRAID-II, and ServeRAID controllers. o Fixed tape backup problems associated with Microsoft Windows 2000. o Fixed system diagnostic problems associated with ServeRAID-4M and ServeRAID-4L controllers. o Fixed diskette drive access problem. This problem occurred when a Netfinity Fibre Channel PCI Adapter or a Netfinity FAStT Host Adapter was installed in the server. 2.5 ServeRAID Family 4.00 to 4.30 __________________________________ o Support for the new IBM ServeRAID-4M Ultra160 SCSI controller and the IBM ServeRAID-4L Ultra160 SCSI controller o ServeRAID Manager has the following new features: - Enhanced reporting and troubleshooting for defunct drives - Setting a physical drive marked with a PFA to defunct. This new action makes drive replacement easier. - Starting the IBM ServeRAID Hot Replace Wizard from a remote connection. This feature is useful when replacing a controller in a server that does not have a monitor attached. 3.0 Installation and setup instructions ________________________________________ NOTE: If your operating system is already installed on a ServeRAID controller, update the ServeRAID device driver before updating the BIOS and firmware. Refer to section 3.3 of this readme.txt file for more information. 3.1 Updating the BIOS and firmware ___________________________________ NOTES: o The ServeRAID-4 controller does not support SCSI CD-ROM drives. o To install a ServeRAID-4 controller in a server with one or more existing ServeRAID controllers, do the following: * Update the BIOS and firmware on the existing controllers using the ServeRAID 4.80 software. * Install the ServeRAID-4 controller in the server. 1. Insert the "IBM ServeRAID Support" CD into the CD-ROM drive or insert the "IBM ServeRAID BIOS and Firmware Update (1 of 2)" diskette into the diskette drive; then, turn on the server. NOTE: When starting the "IBM ServeRAID Support" CD in startable (bootable) CD mode, the ServeRAID ROM Update Wizard might hang if the ServeRAID BIOS level is 3.50 or earlier. To prevent this potential problem, update the ServeRAID BIOS and firmware with the "IBM ServeRAID BIOS and Firmware Update" diskette. 2. Wait for the IBM ServeRAID ROM Update Wizard to start and follow the instructions on the screen. 3.2 Creating logical drives ____________________________ NOTES: o Skip this step if your ServeRAID controller already has been configured with logical drives. o You must create logical drives on the ServeRAID controller before you can use it. 1. After the "IBM ServeRAID Support" CD updates the BIOS and firmware, the ServeRAID Manager will start. You will see an Express/Custom choice on the screen. Choose Express for the ServeRAID Manager to automatically create your logical drives. Choose Custom to manually create your logical drives. 3.3 Installing or updating the device driver _____________________________________________ Install the ServeRAID device drivers that are provided with the IBM ServeRAID controllers on the "IBM ServeRAID Support" CD. Refer to the IBM ServeRAID-4 Ultra160 SCSI Controller Device Driver Installation Instructions (4DEVDRV.PDF) in the /BOOKS directory on the "IBM ServeRAID Support" CD. 3.4 Installing the ServeRAID Manager _____________________________________ Install the ServeRAID Manager that is provided with the IBM ServeRAID controllers on the "IBM ServeRAID Support" CD or from the IBM Support Web site. Refer to the IBM ServeRAID-4 Ultra160 SCSI Controller User's Reference (4SRAIDUR.PDF) in the /BOOKS directory on the "IBM ServeRAID Support" CD for more installation information. To install the ServeRAID Manager from the World Wide Web, use the following instructions: 1. Download the Linux version of the ServeRAID Manager file into a temporary directory, such as /tmp. 2. Type: rpm --install /tmp/.rpm where /tmp is the directory used for the download in step 1 and is the name of the file that was downloaded from the Web. 3. Press Enter. 3.5 Installing the IPSSEND command-line program ________________________________________________ Install the ServeRAID IPSSEND command-line program that is provided with the IBM ServeRAID controllers on the "IBM ServeRAID Support" CD or from the IBM Support Web site. Refer to the IBM ServeRAID-4 Ultra160 SCSI Controller User's Reference (4SRAIDUR.PDF) in the /BOOKS directory on the "IBM ServeRAID Support" CD for more installation information. 4.0 Troubleshooting tips ________________________ 4.1 General ____________ o If you rebuild the Linux kernel, the SCSI-generic support must be included or the ServeRAID Manager program and the IPSSEND command-line program will not work properly. o If you start a server with the "IBM ServeRAID Support" CD in the CD-ROM drive, the following warning message might display: You passed an undefined mode number. Press to see video modes available, to continue or wait 30 secs Press the Spacebar to continue starting the "IBM ServeRAID Support" CD. Then, the following message displays and the CD starts: Uncompressing Linux... Ok, booting the kernel. o If you start a server with the "IBM ServeRAID Support" CD in the CD-ROM drive and a "boot:" prompt appears, then one of following might be preventing the CD from starting: o The Caps Lock or Scroll Lock is set. o The Shift or Alt keys are held. Press at the boot prompt to continue starting the "IBM ServeRAID Support" CD. o If you start a server with the "IBM ServeRAID Support" CD in the CD-ROM drive, and you are unable to eject the CD after exiting the ServeRAID Manager, do the following: 1. Turn off the server. 2. Turn on the server. 3. Press the eject button on the CD-ROM drive. o If you experience problems with SCSI CD-ROM drives connected to a ServeRAID-4 controller, do one of the following: o Use a ServeRAID-3HB or ServeRAID-3L controller instead. o Install an IDE CD-ROM drive in your server. The ServeRAID-4 controller does not support SCSI CD-ROM drives. o If you are running DOS applications in protected mode, you must add the following lines to the CONFIG.SYS: device=x:\himem.sys device=x:\emm386.exe NOEMS where x is the drive where DOS is installed. o If you are installing a ServeRAID-4 controller into a server with one or more existing ServeRAID controllers, and the server fails to start and displays POST code EF10, do the following: 1. Remove the ServeRAID-4 controller from the server. 2. Update the BIOS and firmware on the existing controllers using the ServeRAID 4.80 software. 3. Install the ServeRAID-4 controller in the server. o On a Netfinity server, if your operating system fails to start three times consecutively, the system BIOS will turn off the processor cache. When this happens the "IBM ServeRAID Support" CD behaves unexpectedly. To correct this problem, enter the system BIOS and re-enable the processor cache (or load the default settings). Refer to your system documentation for instructions on entering the system BIOS. o The ServeRAID-4 family of controllers is not compatible with the ServeRAID device driver shipped with RedHat Linux 6.2. To install RedHat Linux 6.2 using the device driver diskette, refer to the "Installation and setup instructions" section of this README.TXT file. Until the other distributions are updated to include the ServeRAID device driver version 4.40 or later, you will be unable to install the operating system to a ServeRAID 4L/4M/4H controller. You can use the ServeRAID-4L/4M/4H controller as secondary storage (non-boot controller) provided that you update the ServeRAID device driver to 4.40 or later prior to installing the ServeRAID-4L/4M/4H controller in your system. o When running the multiple processor kernel, Linux has a problem accessing controllers that are assigned IRQ 9 by the system BIOS. To correct this problem, enter the system BIOS and change the IRQ assigned to each controller. o If you previously installed version 1.00 of the ServeRAID Linux device driver on a kernel without ServeRAID support (stable kernels prior to 2.2.13 and development kernels prior to 2.3.16), you must start with a fresh set of kernel sources before applying the ServeRAID Linux device driver version 4.80 patch. o The Caps Lock key is disabled when using the ServeRAID Manager program in startable-CD (bootable-CD) mode. 5.0 Web Sites and Support Phone Number _______________________________________ o You can download new and updated files for the IBM ServeRAID and Clustering products from the IBM Support Web site: http://www.ibm.com/pc/support/ o With the original purchase of an IBM hardware product, you have access to extensive support coverage.
