— md0 consisting of devices /dev/hpdev/sde and /dev/hpdev/sdf
and
— md1 consisting of devices /dev/hpdev/sdg1 and
/dev/hpdev/mylink-sdh1
use
# md0
RAID_DEVICE[0]=/dev/md0;
DEVICE_0[0]="/dev/hpdev/sde";
DEVICE_1[0]="/dev/hpdev/sdf"
#md1
RAID_DEVICE[1]=/dev/md1;
DEVICE_0[1]="/dev/hpdev/sdg1";
DEVICE_1[1]="/dev/hpdev/sdh1"
The MD RAID device names and the component device names must
be unique across the packages in the entire cluster.
• RAID_MONITOR_INTERVAL
This parameter defines the time interval, in seconds, the raid
monitor script waits between each check to verify accessibility of
both component devices of all mirror devices used by this package.
By default, this parameter is set to 30 seconds.
IMPORTANT After you edit the parameters, ensure that you copy the package control
script and the edited raid.conf file to all nodes in the cluster. All the
nodes in the cluster must have the identical copy of the files.
Although legacy packages are supported, HP recommends that you
configure modular packages in your environment. HP Serviceguard
A.11.18 supports modular packages. For more information on modular
packages see “Configuring Modular Packages for Extended Distance
Cluster Software” on page 88.
