raid

添加阵列：

如果机器支持 hard swap ，直接将第二块硬盘接上去，然后依次执行如下命令，不用重新启动机器。  

第一种方式：

# modunload -i 0  

# drvconfig 

# devlinks  

# disks 

 

第二种方式：

如果新增加了光驱、硬盘、网卡或是更换了显卡、网卡、硬盘等，需要让操作系统重新配置硬件信息。  

#reboot -- -r  

 

命令reboot -- -r用于通知系统重新启动并配置系统的硬件信息。

 

或者在OK模式下boot -r

devfsadm：扫描硬件设备驱动并加载

 devfsadm(1M) maintains the /dev namespace. It  replaces  the

previous  suite  of  devfs  administration  tools  including

drvconfig(1M),     disks(1M),     tapes(1M),      ports(1M),

audlinks(1M), and devlinks(1M).

 

The default operation is to attempt to load every driver  in

the  system  and  attach  to  all possible device instances.

Next, devfsadm creates logical links to device nodes in /dev

and /devices and loads the device policy.

 

devfsadmd(1M) is the daemon  version  of  devfsadm(1M).  The

daemon  is  started during system startup and is responsible

for handling both reconfiguration boot processing and updat-

ing /dev and /devices in response to dynamic reconfiguration

event notifications from the kernel.

 

For  compatibility   purposes,   drvconfig(1M),   disks(1M),

tapes(1M),  ports(1M),  audlinks(1M),  and  devlinks(1M) are

implemented as links to devfsadm.

 

In addition to managing /dev, devfsadm  also  maintains  the

path_to_inst(4) database.

 

 

cfgadm：显示配置信息

                 显示系统组件状态

                 测试系统组件

                 更改组件配置

                 显示配置帮助消息

 

 

 

           The cfgadm  command  provides  configuration  administration

     operations on dynamically reconfigurable hardware resources.

     These operations include displaying status, (-l), initiating

     testing,  (-t),  invoking configuration state changes, (-c),

     invoking hardware specific functions,  (-x),  and  obtaining

     configuration  administration help messages (-h). Configura-

     tion administration is performed at attachment points, which

     are  places  where system software supports dynamic reconfi-

     guration of hardware resources during continued operation of

     Solaris.

 

     Configuration administration  makes  a  distinction  between

     hardware  resources  that  are  physically  present  in  the

     machine and hardware resources that are configured and visi-

     ble  to  Solaris. The nature of configuration administration

     functions are hardware specific, and are performed  by  cal-

     ling hardware specific libraries.

 

     Configuration  administration  operates  on  an   attachment

     point.  Hardware  resources located at attachment points can

     or can not be physically replaceable  during  system  opera-

     tion,  but are dynamically reconfigurable by way of the con-

     figuration administration interfaces.

 

     An attachment point defines two unique elements,  which  are

     distinct  from  the hardware resources that exist beyond the

     attachment point. The two elements of  an  attachment  point

     are  a  receptacle  and  an  occupant. Physical insertion or

     removal of hardware resources occurs  at  attachment  points

     and  results  in a receptacle gaining or losing an occupant.

     Configuration administration supports the physical insertion

     and  removal  operations  as  well  as  other  configuration

metadb：数据区，存放服务器磁盘的所有配置信息

 

阵列中有2块磁盘，将其中一块盘分一个大区作为数据盘，对数据盘做镜像

 

c1t9d0(数据盘)：

用format将c1t9d0分区，本次测验将c1t9d0s5分区为5G空间，将c1t9d0s7分了100m空间作为metadb数据区

 

将c1t9d0s5建立文件系统文件：

newfs /dev/rdsk/c1t9d0s5

 

在/下建一test目录作为挂载点

mkdir /test
