       1.  Patch_SG0003374_Release_Note

       This release note describes patch SG0003374 to IRIX 6.2.

       Patch SG0003374 replaces	patch SG0001397.

       1.1  Supported_Hardware_Platforms

       This patch contains bug fixes for all platforms.


       1.2  Supported_Software_Platforms

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

       1.3  Bugs_Fixed_by_Patch_SG0003374

       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.

       1.4  Bugs_Fixed_by_Patch_SG0001397

	  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)

       1.5  Subsystems_Included_in_Patch_SG0003374

       This patch release includes these subsystems:

	  o patchSG0003374.eoe_sw.unix


       1.6  Installation_Instructions

       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



       1.7  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.
