遷移前確定所有磁盤組在各個節點都已經mount
1、OCR遷移
必須使用root用戶，否則報錯
進入/u01/app/11.2.0/grid/bin目錄
檢查目前ocr配置
./ocrconfig -add +CRS --添加磁盤組到ocr配置，成功時無提示
./ocrcheck --檢查添加結果
![]()
./ocrconfig -replace +DATA -replacement +CRS --替換磁盤組
![]()
./ocrconfig -delete +DATA
./ocrcheck --檢查刪除結果
2、VOTE DISK遷移
查詢表決磁盤位置
crsctl query css votedisk
![]()
crsctl replace votedisk +CRS --遷移命令
3、常見問題：
1、添加CRS到ocrconfig時報錯
PROT-30: The Oracle Cluster Registry location to be added is not usable
PROC-50: The Oracle Cluster Registry location to be added is inaccessible on nodes node2.
solution：檢查磁盤組名稱，掛在狀態是否正確
2、添加CRS到ocrconfig時報錯
PROT-30: The Oracle Cluster Registry location to be added is not usable
PROC-8: Cannot perform cluster registry operation because one of the parameters is invalid.
ORA-15056: additional error message
ORA-17502: ksfdcre:4 Failed to create file +CRS.255.1
ORA-15221: ASM operation requires compatible.asm of 11.1.0.0.0 or higher
ORA-06512: at line 4
使用的asm磁盤組的兼容性屬性的版本太舊
SELECT group_number, name, compatibility, database_compatibility FROM v$asm_diskgroup;
GROUP_NUMBER NAME COMPATIBILITYDATABASE_COMPAT
------------ -------------------------------------------------- --------------- ---------------
1 DATA 11.2.0.0.0 10.1.0.0.0
2 DATAVOTE 10.1.0.0.0 10.1.0.0.0
3 DATAOCR 10.1.0.0.0 10.1.0.0.0
最低要求是11.1.0.0.0
solution：
ALTER DISKGROUP CRS SET ATTRIBUTE 'compatible.asm' = '11.2';
ALTER DISKGROUP CRS SET ATTRIBUTE 'compatible.rdbms' = '10.1';
