In oracle, 11.2 RAC installs a new host to identify the old storage-3-configure the old Storage Database

Install the Oracle 11.2.0.4 database software and execute root. sh. This is nothing special.
Then, we need to modify the ORACLE binary file permissions of oracle RDBMS so that the oracle database process can obtain the ASM disk group.
[Root @ lunar5 ~] # Su-grid
[Grid @ lunar5 ~] $ ORACLE_HOME/bin/setasmgidwrap o =/u01/app/oracle/product/11.2.0.4/dbhome_1/bin/oracle

Note: Here/u01/app/oracle/product/11.2.0.4/dbhome_1/bin/oracle is the ORACLE_HOME for installing oracle rdbms.
Then, add the database to CRS and start the database:
[Oracle @ lunar5 ~] $ Srvctl add database-d lunar-n lunar5-o $ ORACLE_HOME-p + DATADG2/LUNAR/PARAMETERFILE/spfile.272.892409049-s OPEN-y AUTOMATIC-a "TEMPDG, DATADG1, DATADG2, DATADG3 "-t IMMEDIATE
[Oracle @ lunar5 ~] $
Check the configuration of the database in ocr:
[Oracle @ lunar5 ~] $ Srvctl config database-d lunar
Database unique name: lunar

So far, the entire process of identifying the old storage RAC (mainly recognition ASM) with the new host is complete. If it is a file system environment, it is much simpler than this, and all ASM can be omitted.
