10 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.
