HP Tru64 UNIX and TruCluster Server Version 5.1.B-4 Patch Summary and Release Notes (13156)

• NetRAIN virtual interfaces cannot be included in link aggregation groups.
• Ports must be operating in full duplex mode.
• 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 Adminstration:
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.
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.
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 Savings 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.
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 (new) ” (page 34) sections for
information about BIND actions to take when installing this kit.) This new version from the
Internet Software Consortium represents a major rewrite of nearly all aspects of the underlying
BIND architecture. Some of the important features of BIND 9 are:
• DNS Security
— DNSSEC (signed zones)
— TSIG (signed DNS requests)
• IP version 6
— Answers DNS queries on IPv6 sockets
— IPv6 resource records (AAAA)
• DNS Protocol Enhancements
