由于某种故障导致crs的OCR_0001盘掉线，votedisk从3个变为了2个

在第一次掉盘之后rebalance完成之后，又掉一块盘,ocr磁盘组正常,表决盘因为就只有一个磁盘,无法在ocr磁盘组中refresh到其他磁盘上

查询这个时候的ocr磁盘组相关信息

---

可以明显的看到，ocr磁盘组只剩余1个disk,查询表决盘信息

node1-> crsctl query css votedisk

 2. ONLINE   00bc3e79f7404ff2bf60925a7b8a5a6d (/dev/emcpowere) [OCR]
Located 2 voting disk(s).

可以发现表决盘中的两个disk一个属于ocr磁盘组，一个是被ocr磁盘组drop掉的磁盘，尝试增加以前离线的磁盘到ocr磁盘组

由于ORA-600 kfdvfGetCurrent_baddsk错误导致增加磁盘失败,通过上面查询的votedisk的信息,可以发现emcpowerc这个盘虽然ocr中离线,但是依旧还是votedisk盘,因此无法增加到该磁盘组中,采用变通方法,先加另外一块盘

增加成功emcpowerd之后,emcpowerc已经不再是表决盘，变为了emcpowerd,再次增加emcpowerc
