Oracle RAC rebuilds OCR and Votedisk

Haha, just said the last one, idle bored and got a test.

Environment:
Os:redhat 5.8
Db:oracle 10.2.0.5 Raw Device

We should develop the habit of often backing up OCR and Votedisk. However, OCR and Votedisk are not backed up and can be rebuilt. Just like the control file. But the process is more troublesome. The following are the detailed steps:

First back up OCR with Votedisk:

[[email protected] ~]#[[email protected] ~]# ocrcheckstatus of Oracle Cluster Registry is as Follows:v       Ersion:2 Total Space (Kbytes): 1048296 used Space (Kbytes): 3292 Available Space (Kbytes): 1045004 id:1891074113 device/file Nam E:/dev/raw/raw1 device/file integrity check succeeded Device/file Nam E:/dev/raw/raw2 device/file integrity check succeeded Cluster Registr Y integrity check succeeded[[email protected] ~]# crsctl qeury CSS Votediskunknown parameter:qeury[[email      Protected] ~]# crsctl query css Votedisk0.     0/dev/raw/raw31.     0/dev/raw/raw42. 0/dev/raw/raw5[[email protected] ~]# dd if=/dev/raw/raw3 of=/opt/votedisk.bak2097152+0 Records in2097152+0 Recor DS out1073741824 Bytes (1.1 GB) copied, 462.285 seconds, 2.3 mb/s[[email protected] ~]# ocrconfig-export/opt/ocr.bak[[email protected] ~]# cd/opt/[[email  Protected] opt]# Lsocr.bak orclfmap Votedisk.bak

To delete a configuration:
