Package dependency problem

Mauro Gatti — Fri, 24 Jul 2009 07:44:13 GMT

Hi all,
I'm trying to configure package "B" to be dependent from package "A" in this way:

DEPENDENCY_NAME A_dep
DEPENDENCY_CONDITION A=UP
DEPENDENCY_LOCATION SAME_NODE

But when i run cmcheckconf I get the error:
Cannot add a dependency on the failover package A to the package B.

What is wrong?

Thank You

Regards

Oh dear...

So you didn't see this note in the package config file:

# NOTE:
# Dependencies should be used only for a CFS cluster, or by
# applications specified by Hewlett-Packard.
# These are automatically set up in the SYSTEM-MULTI-NODE
# and MULTI-NODE packages created for disk groups and mount points.
# Customers configure dependencies for FAILOVER type
# packages only; and the dependency would be on a MULTI+NODE mount
# point (MP) package

In 11.17 package dependencies were only supported when the package that was "depended" on was a multi-node or system-multi-node package. There was no support for dependencies on standard failover packages.

11.18 removed this restriction:

So yes, I'm afraid I *am* telling you to upgrade to a newer version of Serviceguard... although if you *have* to do this anyway, you should skip straight past 11.18 and go straight to 11.19 which is the latest version...

My eyes read that but my mind filtered it! ;-)
Ok I have to notice my users I'm going to stop their packages to upgrade ServiceGuard.

Thank You
