# NOTE: The Raid Manager command device (RORCM_CMD) cannot be used for
# data storage (it is reserved for private Raid Manager usage).
#/************************ HORCM_MON *************************************/
#
# The HORCM_MON parameter is used for monitoring and control of device groups
# by the Raid Manager.
# It is used to define the IP address, port number, and paired volume error
# monitoring interval for the local host.
# <ip_address>
# Defines a network address used by the local host. This can be a host name
# or an IP address.
# <service>
# Specifies the port name assigned to the Raid Manager communication path,
# which is must also be defined in /etc/services. If a port number, rather
# than a port name is specified, the port number will be used.
# <poll_interval>
# Specifies the interval used for monitoring the paired volumes. By
# increasing this interval, the Raid Manager daemon load is reduced.
# If this interval is set to -1, the paired volumes are not monitored.
# <timeout>
# Specifies the time-out period for communication with the Raid Manager
# server.

#/************************* HORCM_CMD *************************************/
#
# The HORCM_CMD parameter is used to define the special files (raw device
# file names) of the Raid Manager command devices used for the monitoring
# and control of Raid Manager device groups.
# Define the special device files corresponding to two or more command devices
# in order to use the Raid Manager alternate command device feature. An
# alternate command device must be configured, otherwise a failure of a
# single command device could prevent access to the device group.
# Each command device must have alternate links (PVLinks). The first command
# device is the primary command device. The second command device is a
# redundant command device and is used only upon failure of the primary
# command device. The command devices must be mapped to the various host
# interfaces by using the SVP (disk array console) or a remote console.
