解決方法一：
進入Navisphere，點擊Storage Groups -> 選擇你出現鬼盤的Group -> Hosts ->選擇出現鬼盤的host -> 點擊鼠標右鍵 -> Connectivity Status
-> 是不是會看到一個“~management”組
如果看到，選擇WWN地址，然後點擊reconnect按鈕，會把這個WWN地址註冊到你選擇的Group裏。
然後再運行下列步驟刪除鬼盤：
powermt remove dev=all
lsdev -Ct power -F name | xargs -n1 rmdev -dl
lsdev -Ct CLAR_* -F name | xargs -n1 rmdev -dl
/usr/lpp/EMC/CLARiiON/bin/emc_cfgmgr
powermt config
處理“~management”組，方法二（待驗證，慎用）：
go to storage group properties, host tap, enter enginneerit mode (CNTRL+SIFT+F12 ..password "messner"), You will see "Advanced botton". Select it and then look at your host, if there are paths that are not selected go ahead and select them and hit OK.
