HP Serviceguard A.11.20.10 for Linux Release Notes, December 2012

Legacy packages
In A.11.20, you can create new packages using the legacy method (the method used before
Serviceguard A.11.18; see Chapter 7: Configuring a Legacy Package of Managing HP
Serviceguard for Linux). In some cases new capabilities provided in modular packages (those
created by the method introduced in A.11.18) have been added to legacy packages as well.
Use the modular method to create new packages whenever possible. See Chapter 6 of Managing
HP Serviceguard for Linux for more information.
.rhosts deprecated using the .rhosts file as a means of allowing root access to an unconfigured
node is deprecated as of Serviceguard A.11.19. You should use $SGCONF/cmclnodelist
instead. See Chapter 5: Allowing Root Access to an Unconfigured Node of Managing HP
Serviceguard for Linux for more information.
NOTE: Legacy packages will be obsolete from the next major version of Serviceguard.
Quorum server upgrade required if you are using an alternate address
If you are using an Alternate Quorum Server Subnet, you must upgrade the Quorum Server to
version A.04.00 before you upgrade the cluster to Serviceguard A.11.20.00.
CAUTION: If you fail to do this, the upgraded cluster will be running without a cluster lock until
you have upgraded the Quorum Server.
High Availability consulting services
Because Serviceguard configurations can be complex to configure and maintain, HP 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.
