  双机热备份软件(MC/Lock Manager)的几个常用命令
  MC/Lock Manager (Multi-Computer/Lock Manager) 是惠普公司推出专门用 来保护关键业务应用免遭软、硬件故障影响的特殊应用软件。
  使用MC/Lock Manager,多个节点(系统)被组织成一个企业群集,为局域网(LAN) 上的客户机提供高可用性的服务。
  MC/Lock.Manager监控程序监控每一个节点的状态,并且对出现的故障很快 做出反应,使对应用程序的影响减小到最低。

  1. 如何手动启动MC/Lock Manager?
  Start Lock Manager daemons and form a new cluster
  #cmruncl [-f] [-v] [-n NN...]
  [-f] Force cluster startup without warning message
  [-v] Verbose output
  [-n ] specific name(s) of node(s) to
  
  2. 单点启动后如何加入另一个节点?
  Start Lock Manager daemon on node(s) and join a cluster
  cmrunnode [-v] [NN...]
  [-v] Verbose output
  
  3. 如何实现节点切换?
  切换分两种:本地切换 ( Local Switch ) 和 切换 ( Switch )
  当主节点出现网卡故障 ( MAC address or Hardware State Down ) 时,首 先会进行本地切换,备份网卡开始工作;如果此时备份网卡也有故障, 则系统会进行切换,备份节点接管系统工作。
  可以手工模拟这些故障以进行故障诊断或检测。
  
  4. 如何监测 Cluster 运行状态?
  view information about the current Lock Manger cluster
  cmviewcl [-v] [-n NN]... [-p PN]... [-l {package|cluster|node}]
  [-v] Verbose output
  [-n] View information only about the specific node_name(s).
  [-p] package_name... View information only about the specific package_name(s).
  [-l] pkg|clus|node Display only package, cluster or node specific information.
  
  5. 如何停止 Cluster 运行?
  halt Lock Manager cluster daemons
  cmhaltcl [-f] [-v]
  [-f] Force the cluster to shutdown even if packages are currently running.
  [-v] Verbose output
  
  6. 如何停止运行某个节点而 Cluster 在其它节点继续运行?
  
  halt Lock Manager daemon on node(s) and leave the cluster
  cmhaltnode [-f] [-v] [NN...]
  [-f] Force the node to halt even if there are packages running on it.
  [-v] Verbose output
  7. 如何在 Running Cluster 中运行某一个包?
  run a Lock Manager package
  cmrunpkg [-n NN] [-v] PN...
  [-n ] Act on a specific node.
  [-v] Verbose output
  
  8. 如何停止一个运行中的包?
  halt a Lock Manager package
  cmhaltpkg [-n NN] [-v] PN...
  [-n ] Act on a specific node.
  [-v] Verbose output
  
  9. 如何改变一个包的切换属性?
  
  enable or disable switching attributes for a Lock Manager package
  cmmodpkg [-v] [-n NN]... {-e|-d} PN...
  [-v] Verbose output
  [-n ] Modify attributes on specific node(s) - else globally mod.
  -e enable
  -d disable
  PN - package(s) whose switching attributes are changed
