Deinstalling Oracle ASMLIB On Oracle Database

If Oracle ASM library driver (Oracle ASMLIB) is installed but you do not use it for device path persistence, then deinstall Oracle ASMLIB:

1. Stop Oracle ASM and any running database instance:

   $ srvctl stop asm
   

   $ srvctl stop instance -d db_unique_name
   

2. Log in as root.
3. Stop the Oracle Restart stack:

   # cd Grid_home/bin
   

   # crsctl stop has
   

4. Stop Oracle ASMLIB:

   # /etc/init.d/oracleasm disable
   

5. Remove the oracleasm library and tools RPMs:

   # rpm -e oracleasm-support
   

   # rpm -e oracleasmlib
   

6. Check if any oracleasm RPMs are remaining:

   # rpm -qa| grep oracleasm
   

7. If any oracleasm configuration files are remaining, remove them:

   # rpm -qa| grep oracleasm | xargs rpm -e
   

   Oracle ASMLIB and associated RPMs are now removed.
