1.你可以会遇到如下问题
你已经分配磁盘给主机系统,但是在format时无法发现:
# format
Searching for disks...done
AVAILABLE DISK SELECTIONS:
0. c1t0d0
/pci@9,600000/SUNW,qlc@2/fp@0,0/ssd@w500000e0106d9781,0
1. c1t1d0
/pci@9,600000/SUNW,qlc@2/fp@0,0/ssd@w500000e0106ef871,0
Specify disk (enter its number): 1
selecting c1t1d0

2.此时可以使用powermt来检测PowerPath连接状态
Powermt means:PowerPath 4.x Management Utility

这些active dead的状态都是错误的.
3.执行重新配置

此时的active alive状态正常.
