# #
# Module: stoprpdomain #
# #
# Purpose: #
# stoprpdomain - brings an online RSCT peer domain offline. #
# #
# Syntax: #
# stoprpdomain [-h] [-f] [-w [-s Seconds]] [-TV] PeerDomain #
# #
# Flags: #
# -h Help. Writes the command's usage statement to standard #
# output. #
# -f Force. Forces the subsystems to accept the stop request #
# when it otherwise would not, as when resources are #
# allocated, for example. #
# -w Wait. When -w is specified, the command will wait for #
# the peer domain to be offline before the command #
# completes. Use the -s flag to specify how long the #
# command waits. #
# -s Seconds. Used with the -w flag to specify how long in seconds#
# the command is to wait for the peer domain to be offline.#
# If the waiting exceeds the number of seconds, the #
# command returns, but the offline operation continues. The#
# default is 300 seconds (5 minutes). Use 0 to specify #
# that the command should not return until the peer #
# domain is offline (no timeout on waiting). #
# -T Trace. Writes the command's trace messages to standard #
# error. For your software-service organization's use only.#
# -V Verbose. Writes the command's verbose messages to #
# standard output. #
# #
# Operands: #
# PeerDomain The name of the online peer domain to be brought #
# offline. #
# #
# Description: #
# The stoprpdomain command brings all the nodes which are currently#
# online in the peer domain offline. The peer domain definition #
# is not removed from the nodes. #
# #
# The command must be run on a node that is online in the peer #
# domain. If the command is run on a node that is offline to the #
# peer domain, no action is performed. #
# #
# The -f force flag must be used to override a subsystem's #
# rejection of the request to take the peer domain offline. A #
# subsystem may reject the request if a peer domain resource is #
# busy, for example. Specifying the -f force flag in this #
# situation indicates to the subsystems that the peer domain must #
# be brought offline. #
# #
# Exit Values: #
# 0 CRM_CLI_SUCCESS Command completed successfully. #
# 1 CRM_CLI_RMC_ERROR Command terminated due to an underlying #
# RMC error. #
# 2 CRM_CLI_ERROR Command terminated due to an underlying #
# error in the command script. #
# 3 CRM_CLI_BAD_FLAG Command terminated due to user #
# specifying an invalid flag. #
# 4 CRM_CLI_BAD_OPERAND Command terminated due to user #
# specifying a bad operand. #
# 5 CRM_CLI_USER_ERROR Command terminated due to a user error, #
# for example specifying a name that #
# already exists. #
# #
# Examples: #
# 1. To bring the peer domain ApplDomain offline and nodeA is one #
# of the nodes defined and online to this peer domain, run the #
# following command on nodeA: #
# stoprpdomain ApplDomain #
# #
# 2. To bring the peer domain ApplDomain offline, nodeA is one of #
# the nodes defined and online to this peer domain, and the stop#
# request is not to be rejected by any subsystem, run the #
# following command on nodeA: #
# stoprpdomain -f ApplDomain #
# #
# Man Page: #
# For the most current detailed description of this command see #
# the stoprpdomain man page in /opt/rsct/man. #

# General Program Flow/Logic: #
# #
# 1. Parse command line flags and operands. #
# 2. Print usage if -h specified #
# 3. Make sure the cluster exists and is not already offline. #
# 4. Check to see if the force flag was set. #
# 5. Call RMC command stoprsrc. Also pass along -VT if necessary. #
# 6. Return back any errors. #
