# *********************************************************************
#
# RPO_Target
#
# "rpo_target" is used to specify the Recovery Point Objective Target.
# This refers to the maximum time window allowed after which the raid
# system will be disabled to prevent large data loss, resulting in the
# package not being able to start. This is by default set to 0.
# Recommended value is more than the value set for "raid_monitor_interval".
#
# Possible values are:
# 1. -1 - To ignore the rpo_target check during startup
# 2. Any positive integer including zero.
#
# For example, to ignore rpo_target check, configure
# rpo_target -1
# To allow only a maximum of 10 seconds of data loss, configure
# rpo_target 10
#
# Legal values for xdc/xdc/rpo_target: (value >= -1).
xdc/xdc/rpo_target 0
#
# Raid Monitor Interval
#
# "raid_monitor_interval" is the time interval, in seconds, the raid
# monitor script will wait between checks to verify the accessibility
# of the component mirror disks. If the component mirror disk becomes
# accessible, the raid monitor script will add it back to the MD device.
#
# The default value of "raid_monitor_interval" is set to 30 seconds.
#
# Legal values for xdc/xdc/raid_monitor_interval: (value > 0).
xdc/xdc/raid_monitor_interval 30
#
# "raid_device" is used to specify the mirror devices that are used by
# this package.
#
# "device_0" and "device_1" are used to specify the first and the second
# mirror components of the mirror device "raid_device".
#
# The keywords "raid_device", "device_0" and "device_1" are used to specify
# a mirror device and its two component devices. Enter these three parameters
# for each mirror device that this package will use.
#
# The value for "raid_device" is the name of the md mirror device.
#
# The value for "device_0" is the name of the first component mirror half of
# the mirror device defined in the "raid_device"
#
# The value for "device_1" is the name of the second component mirror half of
# the mirror device defined in the "raid_device"
#
# Note: Only persistent device names created using udev must be used as the
# names of the component mirror halves of the raid device.
#
# For example, if this package uses raid devices /dev/md0, having its first
# and second mirror component as /dev/hpdev/mylink-sda and /dev/hpdev/mylink-sdc,
# and /dev/md1, having its first and second mirror component as
# /dev/hpdev/mylink-sdb and /dev/hpdev/mylink-sdd.
#
# enter:
# xdc/xdc/raid_device /dev/md0
# xdc/xdc/device_0 /dev/hpdev/mylink-sda
# xdc/xdc/device_1 /dev/hpdev/mylink-sdc
#
# xdc/xdc/raid_device /dev/md1
# xdc/xdc/device_0 /dev/hpdev/mylink-sdb
# xdc/xdc/device_1 /dev/hpdev/mylink-sdd
