1. Patch SG0003374 Release Note

       This release note describes patch SG0003374 to IRIX 6.2.

       Patch SG0003374 replaces patch SG0001397.

       This patch contains bug fixes for all platforms.

       This patch contains bug fixes for IRIX 6.2 (version
       1232792137).  The software cannot be installed on other
       configurations.

       This patch contains fixes for the following bugs in IRIX
       6.2.  Bug numbers from Silicon Graphics bug tracking system
       are included for reference.

          o The XFS filesystem superblock version number has
            changed in patch 3289 XFS rollup #14 for 6.2 (or one of
            its successors) so that if the new XFS feature is used,
            the resulting XFS filesystem will not be readable by
            the sash in IRIX 6.2.  The feature in question is the
            XFS unwritten extent feature (PV 705217). Root
            filesystems created with the -dunwritten=1 mkfs option,
            or modified to use the new unwritten extent feature via
            the xfs_chver command, cannot be read by sash without
            this patch. Root filesystems created prior to the
            installation of XFS patch 3289, or created with the
            default mkfs -dunwritten=0 option, can be read
            successfully without the installation of this sash
            patch.

            Administrators should also be aware of the new
            xfs_chver command released with the XFS unwritten
            extent feature. The xfs_chver command allows
            administrators to rewrite an XFS superblock version
            number which will enable the unwritten extent feature
            on existing XFS filesystems. Please refer to the
            xfs_chver man page for more information. Administrators
            creating new filesystems should also be aware of the
            new mkfs option "-dunwritten=[0|1]" which will
            disable|enable the XFS unwritten extent feature
            respectively.

          o The XFS filesystem superblock version number has
            changed in patches to IRIX 6.2, so that if the new XFS
            features are used, the resulting XFS filesystem will
            not be readable by the sash in IRIX 6.2.  The primary
            feature in question is quotas; also, any filesystem
            made by a release following IRIX 6.2 would not be
            readable without this patch, but may be readable if
            this patch is installed.  (bug 385316)

       This patch release includes these subsystems:

          o patchSG0003374.eoe_sw.unix

       Because you want to install only the patches for problems
       you have encountered, patch software is not installed by
       default.  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> quit

       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.

No Requirements Information Available.

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):

37072     11 patch/README.patch.3374
01089      1   patchSG0003374
61479    857   patchSG0003374.eoe_sw
