HP Serviceguard Version A.11.18 Release Notes, September 2008

NOTE: Remember to do this exercise not only on the node on which the package will
normally run, but also on the node with the least resources in the cluster, as a failover
or other unexpected circumstances could result in that node running the package.
For more information, see the section “Optimizing for Large Numbers of Storage Units”
in Chapter 6 of the latest edition of Managing Serviceguard (in the High Availability
collection on docs.hp.com) and the comments in the package configuration file.
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.
