Managing Serviceguard Seventeenth Edition, First Reprint December 2009
CAPACITY_VALUE specifies a value for the
CAPACITY_NAME that precedes it. It must be a
floating-point value between 0 and 1000000.
Capacity values are arbitrary as far as
Serviceguard is concerned; they have meaning
only in relation to the corresponding package
weights.
Capacity definition is optional, but if
CAPACITY_NAME is specified,
CAPACITY_VALUE must also be specified;
CAPACITY_NAME must come first.
NOTE: cmapplyconf will fail if any node
defines a capacity and any package has
min_package_node as its failover_policy
(page 268) or automatic as its failback_policy
(page 269).
To specify more than one capacity for a node,
repeat these parameters for each capacity. You
can specify a maximum of four capacities per
cluster, unless you use the reserved
CAPACITY_NAME package_limit; in that
case, you can use only that capacity throughout
the cluster.
For all capacities other than package_limit,
the default weight for all packages is zero, though
you can specify a different default weight for any
capacity other than package_limit; see the
entry for WEIGHT_NAME and
WEIGHT_DEFAULT later in this list.
See “About Package Weights” (page 176) for more
information.
Can be changed while the cluster is running; will
trigger a warning if the change would cause a
running package to fail.
MEMBER_TIMEOUT The amount of time, in microseconds, after which
Serviceguard declares that the node has failed
and begins re-forming the cluster without this
node.
Default value: 14 seconds (14,000,000
microseconds).
