ASMCA needs Oracle Grid Infrastructure to configure ASM

Question

Hi,
I am trying to install ASM 11gR2 on RHEL5. I am using VMWare Workstation for this.
I have already installed Oracle database software and Grid Infrastructure on this machine.While installing Grid Infrastructure, I chose install Grid Infrastructure software only.
Once this was successfull I am trying to create ASM instance using asmca.
Regarding the disks, I am using raw devices. I created a virtual disk which I have partitioned but haven't formatted it. Done this to create raw device
[root@localhost sysconfig]# /bin/raw /dev/raw/raw1 /dev/sdb
/dev/raw/raw1: bound to major 8, minor 16
and have added
ACTION=="add",KERNEL=="sdb",RUN+="/bin/raw /dev/raw/raw1 %N"
to /etc/udev/rules.d/60-raw.rules
Then I tried creating the disk but it failed. So I did the following steps to fix it
[root@dhcppc2 Softwares]# /etc/init.d/oracleasm createdisk VOL1 /dev/sdb
Marking disk "VOL1" as an ASM disk: [FAILED]
[oracle@oracle11gR2 grid]$ tail -f /var/log/oracleasm
Device "/dev/sdb" is not a partition
To fix this
[root@localhost ~]# /usr/sbin/asmtool -C -l /dev/oracleasm -n VOL1 -s /dev/sdb -a force=yes
asmtool: Device "/dev/sdb" is not a partition
asmtool: Continuing anyway
Now I am able to view the asmdisk through listdisks option.
Have set following environment variables before running asmca
[oracle@oracle11gR2 ~]$ export ORACLE_HOME=/u01/app/oracle/product/11.2.0/Grid
[oracle@oracle11gR2 ~]$ export PATH=/u01/app/oracle/product/11.2.0/Grid/bin:/usr/sbin:/usr/kerberos/bin:/usr/local/bin:/usr/bin:/bin:/usr/X11R6/bin:/home/oracle/bin
When I am running ASMCA I am facing this error - Oralce Grid Infrastrcture is not configured properly. ASMCA needs Oracle Grid Infrastructure to configure ASM
Any thoughts?

Hi Aman,
Thanks for the reply.
Is it possible to configure 11gR2 ASM on single instance databases ? I have done the config with 10g but I am struggling with the Grid Infrastructure. For eg: when I do deinstall of Grid Infrstructure
+[oracle@oracle11gR2 deinstall]$ ./deinstall -home /u01/app/oracle/product/11.2.0/Grid+
ORACLE_HOME = /u01/app/oracle/product/11.2.0/Grid

Press Enter after you finish running the above commands
+<----------------------------------------+
I don't see any commands to run but the deinstall blindly says that
"Press Enter after you finish running the above commands"
and while looking at the net I found out it might be something similar to this
/u01/Softwares/oracle11gR2/deinstall/perl/bin/perl -I/u01/Softwares/oracle11gR2/deinstall/perl/lib -I/u01/Softwares/oracle11gR2/deinstall/crs/install /u01/Softwares/oracle11gR2/deinstall/crs/install/rootcrs.pl -force -delete -paramfile /u01/Softwares/oracle11gR2/deinstall/response/deinstall_Ora11g_gridinfrahome1.rsp
Should I run the previous command as root.
Am I doing things in the right way or am I missing something here?
