So, we need brand new 72G FC-AL disk, model ST373307
First try to save old VTOC.

//保持VTOC。如果有必要，应把故障盘的镜像拆除，并清除。

bash-2.05# prtvtoc /dev/rdsk/c0t3d0s2 &gt; /root/c0t3d0s2.vtoc

Now, stop, remove and insert new disk.

sh-2.05# luxadm stop 2000000c508510d4
sh-2.05# luxadm remove_device 2000000c508510d4

//luxadm reove_device -F　也可以接逻辑路径或物理路径。
