This document presents a step by step approach to reinitialize the OCR and Vote Disks without performing a full reinstallation of the 10gR2 or 11Gr1 Oracle Clusterware binaries on Windows platforms.
Note that the procedure in this document is only useful in cases where the Oracle Clusterware Services (including: OracleCSService, OracleEVMService, OracleCRService are intact). If any of these services are missing (such as in the case during a failed upgrade attempt to a higher clusterware version), Oracle Clusterware reinstall will be required.
These steps may be necessary in the following scenarios:
1. To troubleshoot an installation where the Cluster Configuration Assistant (which calls crssetup.config.bat ) has errored out
2. For a cluster that was running fine, but the OCR and/or Vote disks have become damaged or unusable
