Specify disk (enter its number):
c1t3d0和c1t4d0为故障盘
二 拔出故障盘,插上新盘
#devfsadm
#format</dev/null
metastat查看结果:
四 同步数据
metareplace d5 c1t3d0s0 <new device>
metareplace d5 c1t4d0s0 <new device>
五 查看同步结果
Metastat -p
以上是我问个朋友得到的,我在网上查了说 devfsadm 这个是在新加硬盘format前必须做的步骤,
请问这步是做什么的,有什么用?还有format</dev/null这个命令是做什么的?具体作用是什么啊?
请知道的大哥告诉下,谢谢!
