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 (适用于无CLUSTER/LSM/NIS/YP配置的系统) 假设原系统主机名为oldname, 新主机名为newname 1).使用root帐户登录 #rcmgr set HOSTNAME

2). 编辑/etc/hosts文件,做如下改变: ???

127.0.0.1 localhost 16.72.0.156 oldname ??? 改为: ???

127.0.0.1 localhost 16.72.0.156 newname ???

3). # cd /sys/conf

# cp OLDNAME NEWNAME # vi NEWNAME ?.

ident “OLDNAME” ?. 改为: ???

ident “NEWNAME” ??..

4). 编辑/etc/rc.config, 把HOSTNAME从OLDNAME改为NEWNAME 5). # cd /sys/conf

# cp OLDNAME.list NEWNAME.list # cd /sys

# mv OLDNAME NEWNAME 6) # doconfig –c NEWNAME # cp /vmunix /vmunix.bck

# cp /sys/NEWNAME/vmunix /vmunix # shutdown –r now

1. 重起机器， 自检完成后，会出现这一行 “ To discontinue, press any key in 10 seconds ”, 这时你按任意键， 系统会中止启动, 进入Main Menu.

2. 键入“ bo ”, 在系统询问“ Interact with IPL (Y or N?)?”, 输入“y”。 3. 提示符ISL> 后， 输入“ hpux - is ”, 系统进入单用户状态。
