Planning and Documenting an HA Cluster
Package Configuration Planning
Chapter 4182
Specifies the number of concurrent fsck commands to
allow during package startup. The default is 1. (See the
package control script template for more information).
CONCURRENT_MOUNT_OPERATIONS
Specifies the number of mounts and umounts to allow
during package startup or shutdown. The default is 1.
(See the package control script template for more
information).
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 460.
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 in 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
in the package control script. It must be the same as
the name specified for the service in the package ASCII
configuration file.
For each service, enter a SERVICE_NAME,
SERVICE_CMD, and SERVICE_RESTART parameter,
following the directions and examples in the package
control script template. (See the Service Command and
Service Restart Parameter descriptions that follow.)
