The following task mapidentifies the procedures needed to create solaris volume manager volumes using the metassist command. This command enables you to specify volumes based on quality-of-service characteristics and to create sets of layered volumes with a single command:
1,create volumes automatically:
enables you to use the metassist command to create one or more solaris volume manager volumes. Also, enables you to control the amount of information about the volume creation process that the metassist command provides for troubleshooting or for diagnosing problems
2,create a command file:
helps you create a shell script with the metassist command to generate the volumes that the command specifies
3,create a volume with a shell script:
shows you how to create the solaris volumes that the metassist command specified with the shell script previously generated by the command
4,create a volume configuration file:
helps you create a volume configuration file, cescribing the characteristics of the volumes you want to create
5,change the volume defaults file:
allows you to set default volume characteristics to customize the behavior of metassist command
使用metassist命令的语法：
# metassist create -s diskset-name -f -r redudancy -a device1,device2... -S size -v verbosity
其中create是用来创建卷的子命令
-s diskset-name参数是确定使用创建卷的disk set名称
-f参数用来确定和卷相联系的热插拔组件
-r redundancy参数用来确定要创建的冗余等级
用metassist命令创建一个shell脚本：
# metassist create -s diskset-name -f -r redundancy -a device1,device2... -S size -v verbosity [-c]
例如：
# metassist create -s myset -f -r 2 -S 10mb -c
(output truncated)

使用metassist命令将shell脚本保存到一个文件：
# metassist create -s myset -f -r 2 -S 10mb -c > /tmp/metassist-shell-script.sh
执行保存在文本文件里面的shell脚本：
1，确保自从上次保存了shell脚本到文本文件里面之后没有发生变化，并保证你所在路径正是文档所在点
2，执行保存的shell命令
# sh /.metassist-shell-script-name
3，检查状态
# metastat -s diskset-name
