Chapter 4132
service_fail_fast_enabled
For each service, indicates whether or not the failure of
the service will result in the failure of the node. Valid
values are yes or no.
If the parameter is set to yes, and the service fails,
Serviceguard will halt the node on which the service is
running (system halt). The default is no.
service_halt_timeout
In the event of a service halt, Serviceguard will first
send out a SIGTERM signal to terminate the service. If
the process does not terminate, Serviceguard will wait
for the specified timeout before sending out a SIGKILL
signal to force termination.
Define one service_halt_timeout entry for each
service. If you do not provide a value, Serviceguard will
not allow any timeout (0 seconds). The maximum value
is restricted only by the operating system parameter
ULONG_MAX, for an absolute limit of 4,294 seconds.
vgchange_cmd Specifies the method of activation for LVM volume
groups. Details in Chapter 6, under vgchange_cmd
(see page 211), and in the package configuration file.
vg An LVM volume group that will be activated by the
package.
concurrent_fsck_operations
The number of concurrent fsck operations allowed on
file systems being mounted during package startup.
Legal value is any number greater than zero. The
default is 1.
concurrent_mount_and_umount_operations
Specifies the number of concurrent mounts and
umounts to allow during package startup or shutdown.
The default is 1; considering increasing it if the
package will mount a large number of file systems.
