ocr磁盘组掉盘故障处理
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

可以明显的看到,ocr磁盘组只剩余1个disk,查询表决盘信息

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

表决磁盘组从2个变为了3个,ocr磁盘组也恢复了正常的3个,至此OCR掉盘的故障处理完成
