Recently, i was installing 11g grid infrastructure on Oracle Enterprise Linux 5 and due to some reason i have to remove that installation from server and start a fresh installation. This installation was for migrating a existing database to ASM. Following are the process which are active on server after completing the grid infrastructure installation first time. These process are related to ASM only.
[root@NODE1 ~]# ps -ef|grep grid grid 3890 1 0 06:27 ? 00:00:02 /u01/app/grid/product/11.2.0/grid/bin/ohasd.bin reboot grid 4444 1 0 06:28 ? 00:00:05 /u01/app/grid/product/11.2.0/grid/bin/oraagent.bin grid 4457 1 0 06:28 ? 00:00:00 /u01/app/grid/product/11.2.0/grid/bin/tnslsnr LISTENER -inherit grid 4469 1 0 06:28 ? 00:00:00 /u01/app/grid/product/11.2.0/grid/bin/evmd.bin grid 4476 1 0 06:28 ? 00:00:00 /u01/app/grid/product/11.2.0/grid/bin/cssdagent grid 4501 1 0 06:28 ? 00:00:00 /u01/app/grid/product/11.2.0/grid/bin/ocssd.bin grid 4523 4469 0 06:28 ? 00:00:00 /u01/app/grid/product/11.2.0/grid/bin/evmlogger.bin -o /u01/app/grid/product/11.2.0/grid/evm/log/evmlogger.info -l /u01/app/grid/product/11.2.0/grid/evm/log/evmlogger.log grid 4586 1 0 06:29 ? 00:00:00 asm_pmon_+ASM grid 4588 1 0 06:29 ? 00:00:00 asm_psp0_+ASM grid 4590 1 0 06:29 ? 00:00:09 asm_vktm_+ASM grid 4594 1 0 06:29 ? 00:00:00 asm_gen0_+ASM grid 4596 1 0 06:29 ? 00:00:00 asm_diag_+ASM grid 4598 1 0 06:29 ? 00:00:01 asm_dia0_+ASM grid 4600 1 0 06:29 ? 00:00:00 asm_mman_+ASM grid 4602 1 0 06:29 ? 00:00:00 asm_dbw0_+ASM grid 4604 1 0 06:29 ? 00:00:00 asm_lgwr_+ASM grid 4606 1 0 06:29 ? 00:00:00 asm_ckpt_+ASM grid 4608 1 0 06:29 ? 00:00:00 asm_smon_+ASM grid 4610 1 0 06:29 ? 00:00:00 asm_rbal_+ASM grid 4612 1 0 06:29 ? 00:00:00 asm_gmon_+ASM grid 4614 1 0 06:29 ? 00:00:00 asm_mmon_+ASM grid 4616 1 0 06:29 ? 00:00:00 asm_mmnl_+ASM grid 4618 1 0 06:29 ? 00:00:00 oracle+ASM (DESCRIPTION=(LOCAL=YES)(ADDRESS=(PROTOCOL=beq))) root 4851 4810 0 07:05 pts/2 00:00:00 grep grid
Database server is already down on this server. Now, i want to remove above grid infrastructure installation. First, of all shutdown the ASM instance which was created during the earlier installation. Remember that DB is still not migrated to ASM.
SQL> conn sys as sysasm Enter password: Connected. SQL> shutdown immediate; ORA-15100: invalid or missing diskgroup name ASM instance shutdown SQL> exit Disconnected from Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - Production With the Automatic Storage Management option
After shutting down the ASM instance, only the below process exists on server.
[grid@NODE1 grid]$ ps -ef|grep grid grid 3890 1 0 06:27 ? 00:00:03 /u01/app/grid/product/11.2.0/grid/bin/ohasd.bin reboot grid 4444 1 0 06:28 ? 00:00:05 /u01/app/grid/product/11.2.0/grid/bin/oraagent.bin grid 4457 1 0 06:28 ? 00:00:00 /u01/app/grid/product/11.2.0/grid/bin/tnslsnr LISTENER -inherit grid 4469 1 0 06:28 ? 00:00:00 /u01/app/grid/product/11.2.0/grid/bin/evmd.bin grid 4476 1 0 06:28 ? 00:00:00 /u01/app/grid/product/11.2.0/grid/bin/cssdagent grid 4501 1 0 06:28 ? 00:00:00 /u01/app/grid/product/11.2.0/grid/bin/ocssd.bin grid 4523 4469 0 06:28 ? 00:00:00 /u01/app/grid/product/11.2.0/grid/bin/evmlogger.bin -o /u01/app/grid/product/11.2.0/grid/evm/log/evmlogger.info -l /u01/app/grid/product/11.2.0/grid/evm/log/evmlogger.log root 4854 4810 0 07:05 pts/2 00:00:00 su - grid grid 4855 4854 0 07:05 pts/2 00:00:00 -bash grid 4894 4855 0 07:06 pts/2 00:00:00 ps -ef grid 4895 4855 0 07:06 pts/2 00:00:00 grep grid
To remove these process gracefully, follow the steps as below.

Above process is for deinstalling the grid infrastructure gracefully. In case this is not working for you and want to remove all the things forcefully by just deleting the directories from OS, then in that case, it’s a bit pain to remove all the files having information of old installation. I found a good link to manually clean up the installation. Please found link here.
Happy deinstallation 😉
