小机上做raid5 如何操作

这是针对以前老机器的配置方法，现在的都应该是SAS接口的，有所变化，但原理都没变，先做Pdisk，再做Raid。
RAID5安装
       厂家在出厂前应该把RAID卡安装在计算机内。

These programs contain diagnostics, service aids, and tasks for
the system.
These procedures should be used whenever problems
with the system occur which have not been corrected by any
software application procedures available.

In general, the procedures will run automatically.
However,
sometimes you will be required to select options, inform the
system when to continue, and do simple tasks.

Several keys are used to control the procedures:
- The Enter key continues the procedure or performs an action.
- The Backspace key allows keying errors to be corrected.
- The cursor keys are used to select an option.

To continue, press Enter.

      a 查看raid卡的型号
         lsdev  -Cc disk
      b 配置raid
         smit dev -->disk aray--> 选择相应的磁盘阵列-->阵列管理-->Create an Array Candidate pdisk and Format to 522 Byte Sectors-->然后按提示创建阵列收起

还真没做过这样的RAID5，学习了收起

不知raid card bad OS正常嗎?收起

实际操作，不是很复杂收起

好复杂啊收起

一般做mirror 做raid硬盘坏掉数据会丢失的。收起

先做RAID再做系统收起

都是做mirror镜像玩的收起

真不知道在内置盘里面配置raid5会怎么样收起
