Rename Oracle ASM Disk Group On Exadata

When Oracle ACS build Exadata Database Machine, they use the OEDA file that you sent them over for Exadata Install. The Exadata is built with default ASM Disk Group name DATAC1, RECOC1 & DBFS_DG. If you want to rename the DATAC1 and RECOC1 to something different to match your Organization standards you can do that by using the Oracle renamedg utility. The number Database version required to rename an ASM Disk Group is 11.2.

 In this article we will demonstrate how to rename ASM Disk Group on Exadata Database Machine running Oracle Database 11.2

 Here we want to change the following ASM Disk Group Names:
DATAC1 to DATA
RECOC1 to RECO

 Steps to rename ASM Disk Group
  • Get the Database version

ORACLE_SID = [+ASM1] ? dbm011
The Oracle base remains unchanged with value /u01/app/oracle

  • Check the versions

ASMCMD [+] > lsct

DBM01    CONNECTED        11.2.0.4.0          11.2.0.4.0  dbm011         DATAC1

  • Check the database status

[oracle@dm01db01 ~]$ srvctl status database -d dbm01
Instance dbm011 is running on node dm01db01
Instance dbm012 is running on node dm01db02
Instance dbm013 is running on node dm01db03
Instance dbm014 is running on node dm01db04

  • Make a note of the control files, Datafiles, Redo logfiles before stopping the database.

SQL> select name from v$controlfile;
SQL> select name from v$datafile;
SQL> select member from v$logfile;
SQL> select * from v$block_change_tracking;

  • Stop database database

[oracle@dm01db01 ~]$ srvctl stop database -d dbm01

 [oracle@dm01db01 ~]$ srvctl status database -d dbm01
Instance dbm011 is not running on node dm01db01
Instance dbm012 is not running on node dm01db02
Instance dbm013 is not running on node dm01db03
Instance dbm014 is not running on node dm01db04

  • Umount the ASM disk group(s) that you want to rename. Connect to ASM command prompt and umount the disk group. umount the disk group from all nodes.

ASMCMD [+] > umount DATAC1

 ASMCMD [+] > umount RECOC1

 ASMCMD [+] > lsdg

Conclusion

 In this article we have learned how to rename an ASM Disk group on Exadata running Oracle Database 11.2. Starting with Oracle Database 11.2 you can use the renamedg command to rename an ASM Disk Group. renamedg utility cannot rename the associated ASM/Grid disk disk name. Also renamedg cannot rename/update the control files, datafiles, redo log files and any other files that reference ASM DG for all databases. You must update database files manually after renaming ASM disk groups.
