Migrate OCR and VOTEDISK in 11g Rac

Migrate the OCR and VOTEDISK environments in 11g Rac: OEL + oracle rac 11.2.0.3 migration Description: migrate ocr and votedisk from + DATE to + OCR_VOTE. The operation is as follows:

[root@ora2 ~]$ /u01/app/11.2.0/grid/bin/ocrcheckStatus of Oracle Cluster Registry is as follows :         Version                  :          3         Total space (kbytes)     :     1469612         Used space (kbytes)      :       3784         Available space (kbytes) :     1465828         ID                       :  1820175369         Device/File Name         :      +DATA                                    Device/File integrity check succeeded                                    Device/File not configured                                    Device/File not configured         Cluster registry integrity check succeeded         Logical corruption check bypassed due to non-privileged user

 

Here we can see that ocr is placed in + DATA and then Add a new OCR device/file:

[root @ora2 ~]/u01/app/11.2.0/grid/bin/ocrconfig -add +OCR_VOTE[root @ora2 ~]$ /u01/app/11.2.0/grid/bin/ocrcheckStatus of Oracle Cluster Registry is as follows :         Version                  :          3         Total space (kbytes)     :     1469612         Used space (kbytes)      :       3784         Available space (kbytes) :     1465828         ID                       :  1820175369                                    Device/File integrity check succeeded                                    +OCR_VOTE                                    Device/File integrity check succeeded                                    Device/File not configured         Cluster registry integrity check succeeded         Logical corruption check bypassed due to non-privileged user

 

(At this time, ocr does not exist in + OCR_VOTE)

Migrate ocr: [root @ ora2 ~] $/U01/app/11.2.0/grid/bin/ocrconfig-replace + DATA-replacement + OCR_VOTE and migrate votedisk: [root @ ora2 ~] $ Su-grid [grid @ ora2 ~] $ Crsctl replace votedisk + OCR_VOTE query the storage directory of votedisk: [grid @ ora2 ~] $ Crsctl query css votedisk; query the resource status: [grid @ ora2 ~] $ Crsctl status resource-t

 

Then log on to asm to view the information of asmdisk:

[sql] sqlplus / as sysasm  SQL> select group_number,name,state,type from V$asm_diskgroup;  SQL> select group_number,name,path from v$asm_disk;  

 

Use show parameter spfile to view the path. If it is stored in + DATA, you can recreate the spfile:

[sql] SQL>create pfile='/u01/11.2.0/grid/dbs/asmpfile.ora' from spfile;  SQL>create spfile='+OCR_VOTE' from pfile='/u01/11.2.0/grid/dbs/asmpfile.ora';  

 

Then restart crs with the root user.

[root @ora2 ~]$/u01/app/11.2.0/grid/bin/crsctl stop crs[root @ora2 ~]$/u01/app/11.2.0/grid/bin/crsctl start crs

 

Then use the grid user

[sql] su - grid  SQL>alter diskgroup OCR_VOTE mount;  

 

Switch root User

/u01/app/11.2.0/grid/bin/ocrconfig -delete +DATA

 

Delete a disk group + DATA:

[sql] SQL>alter diskgroup DATA dismount;  SQL>drop diskgroup DATA including contents
