HP Tru64 UNIX and TruCluster Server Version 5.1B-5 Patch Summary and Release Notes (March 2009)

• Ports in the same link aggregation group must operate at the same data rate.
• Ports in a link aggregation group must be attached to the same system, either
server-to-server or server-to-switch.
Link aggregation enables system administrators to combine two or more physical
Ethernet Network Interface Cards (NICs) and create a single virtual link. Upper-layer
software sees this link aggregation group as a single virtual interface for example: lag0.
The single virtual link can carry traffic at higher data rates than a single interface because
the traffic is distributed across all of the physical ports that make up the link aggregation
group.
For more information see the Tru64UNIX Technical Overview and the Network
Administration: Connections manual. For tuning and configuration information see the
lag(7), lagconfig(8), sys_attrs_ee(5), sys_attrs_lag(5), and inet_local(4) reference pages.
3.2.1.4 NetRAIN over LAG Supported.
With this release, it is now possible to run NetRAIN over link aggregation (LAG).
Previously, you could not simultaneously use NetRAIN for redundant network devices
and LAG (trunking) on the same network cards. Although the use of LAG provided
redundancy, it could not provide a redundant switch solution because all devices must
be connected to the same switch.
With the installation of this kit, you can run NetRAIN over LAG; that is, have two or
more LAG trunk groups contained within a NetRAIN set. Although only one LAG
group will be active at one time, the benefit is that it allows the use of redundant
switches with a high bandwidth LAG group.
To configure this support, first create your LAG groups, then place each group (lag0,
lag1) into a newly configured NetRAIN set. Refer to the lagconfig(8) and nr(7) reference
pages for details.
3.2.1.5 Support Provided for 2007 Changes to U.S. Daylight Savings Time
This kit updates/etc/zoneinfo time zone data files to incorporate the most recent
changes in various time zones around the world, most notably the US Daylight Saving
Time (DST) rule changes that were passed into law on August 8, 2005 and take effect
in 2007.
That law moves the start of DST from the first Sunday of April to the second Sunday
of March. It moves the return to Standard Time from the last Sunday of October to the
first Sunday of November. These changes affect all US time zones and a number of
other North American time zones in other countries as well.
3.2.1.6 BIND Updated to Version 9.2.5
This kit replaces the current version of BIND (V8.2.2) with BIND Version 9.2.5. (See
the “Commands Must Be Run on BIND Systems After Kit Installation” (page 25)
sections for information about BIND actions to take when installing this kit.) This new
