[Solution] Basically the SLES8.0 running kernel is 2.4.19-64GB-SMP, but the kernel source code is configured for 2.4.19-4GB by default which doesn't have symmetric multi-processing support turned on and High Memory Support is set to 4GB instead of 64GB. Here are the steps to fix this problem. - Run 'rpm -e osa_ipmi' to uninstall OSA IPMI device driver - Change directory to the Linux kernel source top directory, e.g. /usr/src/Linux. - Type 'make menuconfig' - Set the "symmetric multi-processing support" option on under "Processor type and features". - Set "High Memory Support" to 64GB under "Processor Type and features" - Save the setting before exit. - Run 'make dep' to update kernel source - Re-install the OSA IPMI device driver 2) The following message appears while trying to install the osa_ipmidrvr module: Warning: loading /lib/modules/2.4.19-SMP/misc/osa_ipmidrvr.o will taint the kernel: non-GPL license - Proprietary. Copyright 2003-2004 OSA Technologies Inc., an Avocent Company, San Jose, USA. See http://www.tux.org/lkml/#export-tainted for information about tainted modules Module osa_ipmidrvr loaded, with warnings OSA IPMI device driver is covered under OSA End User License Agreement( OSA_EULA.txt) and the shim layer (shimOS.c) which we provide source code along with the package is also covered by (OSA_EULA.txt). Please review the OSA_EULA.txt under /usr/osa/osa_ipmi-2.2.1-1 directory. If you don't accept the agreement or you are not covered by this agreement, please uninstall the OSA IPMI device driver package. This warning message should appear whenever the OSA IPMI device driver is loaded. The warning indicates that our IPMI driver module is not governed by the GPL license - it is not open source. It is covered by OSA End User License Agreement (EULA). In all other respects the driver should work as expected on your system. This warning message should have NO impact on performance or functionality of our driver. 3) For the users working on 32bit SUSE 8.2 whose gcc version is 3.3 20030226 (pre-release) the driver rpm script will complain about the gcc version mismatch and refuse to install the driver. [Solution] You can manually add '-f' option to insmod command in /sbin/ipmi_load script to force the kernel to load the ipmi driver. However, be aware that the '-f' option will cause tainted kernel warning. ====================================================================== 2.0 Linux driver installation ====================================================================== 2.1 Manifest for Linux driver This package contains the following files. build_osadrv -a script to build IPMI 32bit/64bit Linux driver ipmi-i386-redhat*.o -the 32bit pre-compiled driver core object file for Redhat Linux ipmi-i386-suse*.o -the 32bit pre-compiled driver core object file for SUSE Linux ipmi-i386-vmesx.o -the 32bit pre-compiled driver core object file for Vmware ESX server ipmi-x86_64-redhat*.o -the 64bit pre-compiled driver core object file for Redhat Linux ipmi-x86_64-suse*.o -the 64bit pre-compiled driver core object file for SUSE Linux libraw-i386-redhat.so -the 32bit IPMI driver library for Redhat Linux libraw-i386-suse.so -the 32bit IPMI driver library for SUSE Linux libraw-i386-suse9.so -the 32bit IPMI driver library for SUSE Linux Enterprise Server 9 libraw-i386-vmesx.so -the 32bit IPMI driver library for Vmware ESX server libraw-x86_64-redhat.so -the 64bit IPMI driver library for Redhat Linux libraw-x86_64-suse.so -the 64bit IPMI driver library for SUSE Linux libraw-x86_64-suse9.so -the 64bit IPMI driver library for SUSE Linux Enterprise Server 9 make.shim -makefile for "shim" layer README -this file shimOS.c -the source of Linux "shim" layer 2.2 legal and license information OSA IPMI driver is written as a kernel loadable module. It has two pieces. One piece contains a shim layer which deals with all kernel dependencies, e.g. kernel version and configuration for UP or SMP etc.. We provide source code for our shim layer. A second piece is a pre-compiled binary object file ipmi-xxx.o. It contains proprietary logic for all IPMI implementations. During driver installation, the shim code will be compiled and linked with the pre-compiled ipmi-xxx.o file to generate a final driver module, osa_ipmidrvr.o (or osa_ipmidrvr.ko), and install under /lib/modules/kernel-version/misc directory. 2.3 Driver Building and Installation To install the driver, launch a Linux shell and type: "rpm -i osa_ipmi-x.x.x-x.i386.rpm", it will build and install the driver module on your system. If you want to rebuild the driver, change to /usr/osa/osa_ipmi-x.x.x-x and launch a Linux shell and type: "sh build_osadrv". Building Environments: 1) Please install the necessary source code packages on your system. Recommended directory: /usr/src; 2) Make sure you have gcc 3.2 available. Also remember to upgrade your binutils package (for as/ld/nm and company) if necessary. [Note] 1) For the users working on 32bit SUSE 8.2 whose gcc version is 3.3 20030226 (pre-release), insmod does not work without '-f' option. Please manually add '-f' option to insmod command in /sbin/ipmi_load script for the force loading. However, the '-f' option will cause tainted kernel warning. 2) Other gcc version may cause the same problem. 2.4 Driver uninstallation To uninstall the driver, launch a Linux shell and type: "rpm -e osa_ipmi-x.x.x-x" or "rpm -e osa_ipmi" 2.5 Linux Kernel Upgrade If you upgrade your Linux kernel, we strongly recommend you to uninstall, recompile/re-install the OSA IPMI device driver. Please refer to above section for building environments and steps to rebuild and install the driver. 2.6 Loading driver with /sbin/ipmi_load The driver will read SMBIOS record 38 (see Appendix C1 of IPMI 1.5 spec) and probe the default interface exists. 2.7 Unloading driver with /sbin/ipmi_unload To manually unload the ipmi driver, run '/sbin/ipmi_unload' from Lunix shell. 2.8 Have driver working on two or more identical platforms without re-compiling To move already compiled IPMI driver onto other identical machines, Please build the driver on one machine and then copy the following files to the target machines: /sbin/ipmi_load /sbin/ipmi_unload /lib/libraw.so /lib/modules//extra/osa_ipmidrvr.ko (or osa_ipmidrvr.o) /etc/rc.d/rc.modules (for redhat) /etc/rc.d/boot.local (for SLES) ====================================================================== 3.0 VMware ESX driver installation ====================================================================== 3.1 To install OSA IPMI driver on VMware ESX server 1) In the LILO Boot Menu, choose "ESX" to boot into VMware ESX Server. 2) Press Alt-F2 to login. 3) Make sure gcc is installed. You can verify this by issuing command "rpm -qi gcc". If gcc is not installed, you can find the gcc-x.x-x.x.x.i386.rpm package in VMware ESX CD. 4) Install OSA IPMI driver by typing "rpm -i osa_ipmi-x.x.x-x.i386.rpm", it will build and install the driver module on your system. If you want to rebuild the driver, change to /usr/osa/osa_ipmi-x.x.x-x and type: "sh build_osadrv". 5) Ignore the warning message (please refer to section 1.3-2), the driver should now be functioning. 6) To uninstall the driver, type: "rpm -e osa_ipmi-x.x.x-x" or "rpm -e osa_ipmi". ====================================================================== 4.0 Change log ====================================================================== * version 2.3.7 on 04-06-2006 * - add support for 32 bit SLES 9.2 and 9.3 -------------------------------------------------------------------- * version 2.3.6 on 03-30-2006 * - add support for RHEL 4.3 32/64 - add support for 64 bit SLES 9.2 and 9.3 -------------------------------------------------------------------- * version 2.3.5 on 12-05-2005 * - add aupport for 32 bit SLES 8 sp3 and sp4. - add support for SLES 10 beta -------------------------------------------------------------------- * version 2.3.4 on 09-06-2005 * - fixed OSA driver 2.3.3-1 uses rc.local instead of init scripts.
