一、通过串口（使用180-0055转接头）接入node的MFG口，3paradm用户登录系统，使用showpd -c命令查看硬盘状态，确认状态为failed.

二、使用servicemag status -d命令确认servicemag start操作已经完成。
SS7400 cli% servicemag status -d
Cage 5, magazine 17:
The magazine was successfully brought offline by a servicemag start command.
The command completed Sat Aug 16 21:13:33 2014.
The output of the servicemag start was:
servicemag start -pdid 131
... servicing disks in mag: 5 17
... normal disks:
... not normal disks: WWN [5000CCA0224BCD63] Id [131] diskpos [0]
... relocating chunklets to spare space...

... bypassing mag 5 17

servicemag start -pdid 131 -- Succeeded

三、换盘，等待几分钟后，系统自动执行servicemag resume操作，可以看到chunklet迁移耗时。
SS7400 cli% servicemag status -d
Cage 5, magazine 17:
The magazine is being brought online due to a servicemag resume.
The last status update was at Thu Aug 21 15:29:38 2014.
Chunklets relocated: 10 in 7 minutes and 3 seconds
Chunklets remaining: 258
Chunklets marked for moving: 258
Estimated time for relocation completion based on 42 seconds per chunklet is: 3 hours and 36 seconds
The cumulative output so far is:
servicemag resume 5 17
... mag 5 17 already onlooped
... firmware is current on pd WWN [5000CCA02263CCBB]
... firmware is current on pd WWN [5000CCA0224BCD63] Id [131]

四、确认新盘状态为degraded，需要等到chunklets迁移完成，盘的状态才会变normal，旧盘标记会自动消失。
