在存储上划分LUN并map到主机，用format命令已经识别出map过来的LUN。

但用vxdisk list命令查看磁盘时，磁盘状态为error。

root@node1:/ #> vxdisk list

c2t0d3s2     auto:none       -            -            online invalid
c3t0d4s2     auto            -            -            error

用vxdisksetup初始化磁盘时，显示"dmpnode xxxxx is disabled”。

root@node1:/ #> vxdisksetup -i c3t0d4
VxVM vxdisksetup ERROR V-5-2-3628 The dmpnode c3t0d4s2 is disabled.Can not
proceed with vxdisksetup.

再次使用format命令查看error对应的磁盘时，发现磁盘未做label。
