As of August 8, 2001 IRIX 6.5.13 is releasing with all new systems
shipping from SGI worldwide manufacturing centers.
The IRIX 6.5.13 release contains updates for both the maintenance
(6.5.13m) and feature (6.5.13f) streams. This release continues the
focus on stability, reliability and compatibility required in the
IRIX 6.5.X quarterly release process.
Approximately 133 customer reported incidents are fixed in this release.
In addition to bug fixes, the IRIX 6.5.13 maintenance path delivers
several software enhancements and additional installation improvements.
Since a major goal of the IRIX 6.5.X release process is to provide a
feature stream as stable as the maintenance stream, the same bug fixes
and software enhancements are also applied to the IRIX 6.5.13 feature path.
The general distribution process is through the online ordering system.
IRIX 6.5.13m and 6.5.13f images are also available for download off Supportfolio.
Summary of Software Enhancements delivered by IRIX 6.5.13
Maintenance and Feature Stream:
- Improved exit codes for the xfsrestore and xfsdump commands.
- Changed the mkfs command to allow you to specify the size of an XFS allocation group, as an alternative to specifying the total number of allocation groups.
- Changed the mkfs command to allow you to specify the size of a stripe unit and the size of a stripe width in bytes or in filesystem blocks, as an alternative to specifying these values in 512-byte block units.
- Changed the default size of an XFS allocation group; larger filesystems
will result in larger default allocation group sizes.
- The xfsdump and xfsrestore commands will provide the VSN of the tape that reached its end-of-volume (or the VSN of a new tape that needs to be mounted) and pass this VSN to the media_change_alert_program specified with the -c option.
- Changed the default size of an XFS log. The default log size grows with the size of the filesystem up to the maximum log size, 128 megabytes, on a 1 terabyte filesystem.
- Added cpusetAttachPID() and cpusetDetachPID() functions to the Cpuset System library. These functions allow a programmer to attach/detach a currently running program to an existing cpuset.
- The following features have been moved from Enhanced DHCP to standard DHCP:
- Ping check before an address is leased to insure it is not already in use.
- MAC address filtering.
- Added implementation of End Sequence to Scheduled Transfer Protocol.
- VPro for Octane/OpenGL performance improvements have been added as
- Improved X window performance by 25 percent based on x11perf.
- Iproved performance of OpenGL glCopypixel() function.
SGI Origin 3000 servers
- The following new system controller features have been implemented
for the SGI Origin 3000 server series:
- Enabled router port security.
- Enabled system serial number security.
- Redesigned the graphical interface for the front-panel display of
the SGI 3400 and 3800 servers.
Added hotplug attach feature that allows Gigabit Ethernet cards to
be installed on a running system.
- Added Origin 3000 system partitioning support in the eoe.sw.partition
- Efficiency improvements have been made to the BTE driver layer to
reduce both latency and contention.
- The tools that report CPU utilization have been modified to correct
the sampling of %WIO to omit idle time in line with industry standards.
- Updated FLEXlm v7.2f support from GLOBEtrotter Software, Inc.
The license manager daemon and the floating license server are built
in V5 compatibility mode. For backwards compatibility, the client
libraries and header files are still based on FLEXlm v6.1g.
- The structure of the CXFS filesystem configuration has been changed.
CXFS filesystems can now be defined, modified, managed and deleted
independently of each other, and of the cluster definition.
- The XVM Volume Manager can be used when layered with the CXFS
filesystem. The XVM Volume Manager can also be used as a standalone
volume manager; this requires that you be running (6.5.13f) feature
stream. The (6.5.13m) maintenance stream does not support XVM as a
standalone volume manager; this support is planned for a later release.
- Added support for the use of mirrors in XVM logical volumes.
The mirroring feature of XVM requires the XFS Volume Plexing software
option. Customers running CXFS and who want to run mirrors will need
to purchase this license. XLV customers with plexing licenses can
upgrade to XVM without having to acquire a new license.
- The following products were updated with bug fixes only:
- SGI Web Server, based on the Apache 1.3.20
- IRIX Interactive Desktop System Administration
- Information Searching Execution Environment
- InSight Online Doc Viewer 4.4
- Netscape Communicator 4.77
By default, version 4.77 will install the new N32 version of the
browser. Any existing third-party plugins for the browser that are
O32 will no longer function. Support for the Macromedia Flash plugin
is also included.
- The following products contain enhancements or new features:
(For more information on support modes, see the Support Policy page at
- WebSetup 3.3 has been updated to support the SGI web server based
on Apache 1.3.20 and an administration GUI has been added.
- Impressario 2.9.5 to support a new HP6300 Scanner driver and an
Epson PPD bug fix.
IRIX 6.5 Application Compatibility Mandate
For those providers asking about quarterly recertification of
applications, please take a moment and become acquainted with the
application compatibility protections offered by IRIX 6.5. This is a
very powerful mandate that allows an application to be developed under
IRIX 6.5.X and be run on any IRIX 6.5.Y, regardless of whether
Y > X, Y == X, or Y < x.

IRIX 6.5.X Lookahead
IRIX 6.5.14 is in development and is planned to release mid-November, 2001
- Planned default change in IRIX 6.5.14
In the IRIX 6.5.5 release, SGI introduced a new optional directory
format for XFS filesystems, referred to as the "version 2" directory
format in mkfs output.
XFS filesystems with a version 2 directory format can provide improved
reliability and performance over filesystems with a version 1 directory
format in some applications, particularly for applications that use NFS
exported XFS filesystems.
The directory format for an XFS filesystem is specified with the
-n parameter of the mkfs command. The default directory format is
currently the original version 1 directory format.
Beginning with the IRIX 6.5.14 release, version 2 directories of XFS
will be the default for all new filesystems created with mkfs.
Version 1 directory filesystem creation will still be supported, but
this will require that you specify the -n version=1 parameter of the
SGI recommends that all new XFS filesystems be created with version 2
directories. IRIX releases older than IRIX 6.5.5, however, will not be
able to mount a filesystem created with a version 2 directory and will
issue the following message when a mount is attempted:
Wrong filesystem type: xfs
Many SGI customers are currently running production servers
with version 2 directories. Should you wish to format filesystems
with the version 2 directory format prior to the 6.5.14 release
you can specify the following option of mkfs:
mkfs -n version=2
There is no means for converting a filesystem, in place, between
version 1 and version 2 directories. A filesystem can be converted
between version 1 and version 2 directories by means of an
