11gR2 modify resource to autostart after creating pfile

then modify the resource attributes to start automatically.
For ASM in 11gR2-11.2.0.2:
I created pfile from spfile and started the instance with pfile:

SQL> startup pfile='PATH/init+ASM1.ora';
ASM instance started

Total System Global Area 2120624 bytes
Fixed Size 2212656 bytes
Variable Size 27289364 bytes
ASM Cache 3214564 bytes
*ORA-15110: no diskgroups mounted*

checked the diskgroups:
check the resource is online or offline by:
crsctl status resource -t

Then add the resources that are offline to auto start by:

>crsctl modify resource "ora.DATA_01.dg" -attr "AUTO_START=1"

slpnprdb09cdp(+ASM) /export/home/oracle
>crsctl modify resource "ora.FRA_01.dg" -attr "AUTO_START=1"


SQL> startup
ASM instance started

ASM device reuse

You want to re use the ASM devices .

in of(output file) give the lun path/storage device path

>dd if=/dev/zero of=/dev/oracle/ASM09/disk16g_t1_0003 bs=1024 count=1000
1000+0 records in
1000+0 records out

Cannot configure two CRS instances on the same cluster

Error:
CRS-4000: Command Pin failed, or completed with errors.
you were not able to pin server for the crs installation.

cause:
didn't cleanup the previous Grid infrastructure software properly or existing ASM installation or previous install gone bad

resolution: Run the below as root:
/grid_install_home/crs/install/roothas.pl -delete

How to remove 11gR2 grid infrastructure.
