The following task map identifies the procedures that are needed to manage solaris volume manager's 5 volumes:
1,create RAID-5 volumes:use the solaris volume manager GUI or the metainit command to create RAID-5 volumes
2,check the status of RAID-5 volumes:use the solaris volume manager GUI or the metastat command to check the status of RAID-5 volumes
3,expand a RAID-5 volume:use the solaris volume manager GUI or the metattach command to expand RAID-5 volumes
4,enable a slice in a RAID-5 volume:use the solaris volume manager GUI or the metareplace command to enable slices in RAID-5 volumes
5,replace a slice in a RAID-5 volume:use the solaris volume manager GUI or the metareplace command to replace slices in RAID-5 volumes
创建RAID-5卷的步骤：
# metainit volume-name -r component component component -i interlace-value
例如：
# metainit d45 -r c2t3d0s2 c3t0d0s2 c4t0d0s2
检查一个RAID-5卷的状态的步骤：
# metastat [-s diskset] [volume]
扩展一个RAID-5卷的步骤：
# metattach volume-name name-of-component-to-add
例如：
# metattach d2 c2t1d0s2
HOW TO ENABLE A COMPONENT IN A RAID-5 VOLUME:
# metareplace -e volume-name component-name
例如：
# metareplace -e d20 c2t0d0s2
HOW TO REPLACE A COMPONENT IN A RAID-5 VOLUME:
1，确保当前的所有数据都已经做好备份
2，查看卷的状态来判断卷的哪个分区需要被移除
# metastat volume
3，用新的分区替换坏的分区
# metareplace volume-name failed-component new-component
4，用命令metastat查看新更换的分区是否运行良好
# metastat volume
例如：
# metastat d1
