HP Serviceguard Version A.11.19 Release Notes, March 2009

High Availability Consulting Services
Because Serviceguard configurations can be complex to configure and maintain, HP
strongly recommends that you use its high availability consulting services to ensure a
smooth installation and rollout; contact your HP representative for more information.
You should also work with your HP representative to ensure that you have the latest
firmware revisions for disk drives, disk controllers, LAN controllers, and other
hardware.
Announcements for HP-UX 11i v2
Possible Problem when Upgrading from HP-UX 11i v1 to 11i v2
Under certain rare conditions the Serviceguard daemon /usr/lbin/cmclconfd
could abort with a core dump during a system update from HP-UX 11i v1 to 11i v2 on
a system on which EMS is installed.
This can happen if the Serviceguard node being updated receives a Serviceguard probe
request from another Serviceguard node on the subnet while the EMS product is being
updated.
During the EMS product update, the EMS libraries on which cmclconfd depends are
removed and re-installed, leaving a very short period during which the system does
not have an EMS library.
If the node receives a Serviceguard probe request during this time, the system will fail
to load the EMS library and will send a SIGABORT signal to cmclconfd. The core
dump created as a result of this is harmless and does not affect the product or system
functionality in any way.
Once the EMS library is installed, cmclconfd will provide normal functionality.
Use -T option to identd
A new option, -T, is available for the HP-UX daemon identd. You can obtain this
version of identd for an HP-UX 11i v2 system by downloading Sendmail release 8.13.3
(version B.11.23.1.005 or later): go to http://www.software.hp.com -> Internet
ready and networking and choose Sendmail 8.13.3 Special Release
Upgrade.
The download includes Release Notes; follow directions in that document to install
the upgrade.
Once you have downloaded the software, set the identd -T option to 120 (-T120);
this ensures that a connection inadvertently left open will be closed after two minutes.
identd is usually started by inetd from /etc/inetd.conf, so you would normally
edit that file to set the identd -T option.
The -T option may also be available in the form of a patch to earlier Sendmail versions;
or for later HP-UX versions. (And if you are still running some clusters under
