After reading the descriptions of the bugs fixed in this patch (see Section 1.3), determine the patches that meet your specific needs. If, after reading Sections 1.1 and 1.2 of these release notes, you are unsure whether your hardware and software meet the requirements for installing a particular patch, run inst. The inst program does not allow you to install patches that are incompatible with your hardware or software. Patch software is installed like any other Silicon Graphics software product. Follow the instructions in your Software Installation Administrator's Guide to bring up the miniroot form of the software installation tools. Follow these steps to select a patch for installation: 1. At the Inst> prompt, type install patchSGxxxxxxx where xxxxxxx is the patch number. 2. Initiate the installation sequence. Type Inst> go 3. You may find that two patches have been marked as incompatible. (The installation tools reject an installation request if an incompatibility is detected.) If this occurs, you must deselect one of the patches. Inst> keep patchSGxxxxxxx where xxxxxxx is the patch number. 4. After completing the installation process, exit the inst program by typing Inst> quit1.6 Patch Removal Instructions To remove a patch, use the versions remove command as you would for any other software subsystem. The removal process reinstates the original version of software unless you have specifically removed the patch history from your system. versions remove patchSGxxxxxxx where xxxxxxx is the patch number. To keep a patch but increase your disk space, use the versions removehist command to remove the patch history. versions removehist patchSGxxxxxxx where xxxxxxx is the patch number.1.7 Known Problems 1.7.1 Bug 284409 The fixes for bug 284409 require that patch #2400 (or later) also be installed. patch #2400 and patch #2054 (or later) may be installed in either order. If patch #2400 is not installed, then the complete fixes for bug# 284409 will not be present and there is the possibility that the kernel may panic when svr4net is enabled (rpcbind) and used under load. INST SUBSYSTEM REQUIREMENTS No Requirements Information Available. INST SUBSYSTEM CHECKSUMS These checksums help to provide a 'signature' for the patch inst image which can be used to authenticate other inst images. You can obtain this kind of output by running sum -r on the image (from the command line): 38616 2252 patchSG0003255.eoe_sw 42842 5 patchSG0003255.eoe_hdr 00549 11 patch/README.patch.3255 53193 6 patchSG0003255 03519 1 patchSG0003255.nfs_sw INST SUBSYSTEM FILE LISTINGS The following lists the files which get installed from each subsystem in the patch:
