Managing Serviceguard Nineteenth Edition, Reprinted June 2011

NOTE: cmquerycl (1m) detects first-level routers in the
cluster (by looking for gateways in each node's routing
table) and lists them here as polling targets. If you run
cmquerycl with the -w full option (for full network
probing) it will also verify that the gateways will work
correctly for monitoring purposes.
Can be changed while the cluster is running; must be
removed if the preceding SUBNET entry is removed.
MAX_CONFIGURED_PACKAGES This parameter sets the maximum number of packages that
can be configured in the cluster.
The minimum value is 0, and the maximum value is 300.
The default value is 300, and you can change it without
halting the cluster.
WEIGHT_NAME, WEIGHT_DEFAULT Default value for this weight for all packages that can have
weight; see “Rules and Guidelines” (page 141) under“About
Package Weights” (page 135). WEIGHT_NAME specifies a
name for a weight that exactly corresponds to a
CAPACITY_NAME specified earlier in the cluster
configuration file. (A package has weight; a node has
capacity.) The rules for forming WEIGHT_NAME are the same
as those spelled out for CAPACITY_NAME earlier in this list.
These parameters are optional, but if they are defined,
WEIGHT_DEFAULT must follow WEIGHT_NAME, and must
be set to a floating-point value between 0 and 1000000.
If they are not specified for a given weight, Serviceguard
will assume a default value of zero for that weight. In either
case, the default can be overridden for an individual
package via the weight_name and weight_value
parameters in the package configuration file.
For more information and examples, see “Defining Weights”
(page 139).
IMPORTANT: CAPACITY_NAME, WEIGHT_NAME, and
weight_value must all match exactly.
NOTE: A weight (WEIGHT_NAME, WEIGHT_DEFAULT)
has no meaning on a node unless a corresponding capacity
(CAPACITY_NAME, CAPACITY_VALUE) is defined for that
node.
For the reserved weight and capacity package_limit,
the default weight is always one. This default cannot be
changed in the cluster configuration file, but it can be
overridden for an individual package in the package
configuration file.
cmapplyconf will fail if you define a default for a weight
but do not specify a capacity of the same name for at least
one node in the cluster. You can define a maximum of four
WEIGHT_DEFAULTs per cluster.
Can be changed while the cluster is running.
