Managing HP Serviceguard for Linux, Tenth Edition, September 2012

below. If HOSTNAME_ADDRESS_FAMILY is set to
IPV6, all the IP addresses used by the cluster must
be IPv6 addresses.
If you want to separate application data from
heartbeat messages, define one or more
monitored non-heartbeat subnets here. You can
identify any number of subnets to be monitored.
A stationary IP address can be either an IPv4 or
an IPv6 address. For more information about IPv6
addresses, see “IPv6 Address Types” (page 328).
For information about changing the configuration
online, see “Changing the Cluster Networking
Configuration while the Cluster Is Running”
(page 267).
CAPACITY_NAME,
CAPACITY_VALUE
Node capacity parameters. Use the
CAPACITY_NAME and CAPACITY_VALUE
parameters to define a capacity for this node.
Node capacities correspond to package weights;
node capacity is checked against the
corresponding package weight to determine if the
package can run on that node.
CAPACITY_NAME name can be any string that
starts and ends with an alphanumeric character,
and otherwise contains only alphanumeric
characters, dot (.), dash (-), or underscore (_).
Maximum length is 39 characters.
CAPACITY_NAME must be unique in the cluster.
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.
