Managing Serviceguard 11th Edition, Version A.11.16, Second Printing June 2004

Planning and Documenting an HA Cluster
Package Configuration Planning
Chapter 4174
Specifies the number of mounts and umounts to allow
during package startup or shutdown. The default is 1.
Setting this variable to a higher value may improve
performance while mounting or unmounting a large
number of file systems. If a value less than 1 is
specified, the script defaults the variable to 1 and
writes a warning message in the package control script
log file.
IP Addresses and SUBNETs
These are the IP addresses by which a package is
mapped to a LAN card. Indicate the IP addresses and
subnets for each IP address you want to add to an
interface card. Package IP addresses may be either
IPv4 addresses or IPv6 addresses. For more details of
IPv6 address format, see the Appendix , “IPv6 Address
Types,” on page 424
In the package control script file, these variables are
entered in pairs. An IPv4 example is
IP[0]=192.10.25.12 and SUBNET[0]=192.10.25.0.
(In this case the subnet mask is 255.255.255.0.) An
IPv6 examples is IP[0]=2001::3 and
SUBNET[0]=2001::/64. (In this case the subnet mask
is ffff:ffff:ffff:ffff::.)
Service Name
Enter a unique name for each specific service within
the package. All services are monitored by
Serviceguard. You may specify up to 30 services per
package. Each name must be unique within the cluster.
The service name is the name used by cmrunserv and
cmhaltserv inside the package control script. It must
be the same as the name specified for the service in the
package ASCII configuration file.
In the package control script file, enter values into an
array known as SERVICE_NAME. Enter one service name
for each service. The SERVICE_NAME, SERVICE_CMD, and
SERVICE_RESTART parameters are set in the package
control script in groups of three.
