IRIX 6.5.28 Released

SGI has updated IRIX to version 6.5.28 which is now available for download from SGI's Supportfolio website.

As of this posting Techpubs and the SGI Products page hasn't been updated to reflect the 6.5.28 release. Here's a list of new features as posted in the forum:

IRIX 6.5.28 Key New Features

The following changes have been incorporated into the core IRIX 6.5.28 overlay CDs and the Applications CD.
New Software Enhancements

* Expanded support for diskless workstation
For the IRIX 6.5.28 release, the diskless workstation feature is now supported with the following systems:

o Regular Origin 300/350/3000 servers

o IP35 machines with KONA graphics

o IP35 machines with VOYAGER graphics

IP35 machines with ODYSSEY graphics were supported prior to this release.

For information on diskless workstations, see the Diskless Workstation Administration Guide.

* Increased maximum allocation group size in XFS filesystems
For the IRIX 6.5.28 release, xfs filesystems support a maximum allocation group size of up to 1 terabyte. This requires that you use the -d largeag option of the mkfs command. For information on allocation groups see the mkfs(1M) man page and IRIX Admin: Disks and Filesystems.

* Directory quotas
For the IRIX 6.5.28 release, you can set quotas on a per-directory basis. This allows you to have a quota for all files and subdirectories starting at any given directory. For information on setting directory quotas, see IRIX Admin: Disks and Filesystems.

* Audit logs
In the IRIX 6.5.28 release, an audit record is added to the audit log when a user logs in or logs out from ftp.

* Improved netgather script
In the IRIX 6.5.28 release, the netgather script now collects additional NFS information about mounted filesystems that can aid in customer support.

* Symbolic links in AutoFS filesystems
In IRIX 6.5.28, support for symbolic links has being added to the AutoFS filesystem. This new feature allows users to avoid using LoFS filesystems for accessing directories on the local host via autofs mounts. For information, see the -L option in the autofsd(1M) man page.

* ISO 9660 filesystem support for large filesystems
IRIX 6.5.28 adds support for ISO 9660 filesystems larger then 2GB.

* Failsoft support
The Irix 6.5.28 release supports failsoft modes of operation. With the incorporation of failsoft operation modes, certain fatal hardware errors are able to be confined, affecting only the work running in a cpuset, and therefore do not result in system crash. The running job on the affected cpuset is suspended, and no further work is allowed to be submitted to the cpuset. The other cpus within the cpuset are released from the cpuset to be rescheduled by the system to continue doing useful work. The failed CPU is held in an isolated, unusable state pending administrative action to remedy. This feature does not require any user or administrative intervention to take effect.

For information on cpusets, see IRIX Admin: Resource Administration and the cpuset(5) man page.
