I am a bit confused.

11g ASM supports 10G RDBMS
If I was running an 11g ASM instance I would start the occsd using  the 11G 
binaries whether or not the 10G occsd binary worked
Remember to get you compatibility settings correct


col COMPATIBILITY form a10

col DATABASE_COMPATIBILITY form a10

col NAME form a20

col VALUE form a10

select group_number, name, compatibility, database_compatibility

from v$asm_diskgroup;



alter diskgroup data set attribute 'compatible.rdbms'='10.2';



alter diskgroup data set attribute 'compatible.asm'='11.1';


(or whatever is appropriate)

Listers,

On our non-rac environment we have upgraded 10g ASM home to 11g ASM home.Can we 
mount diskgroup belonging to 10g RDMS  from 10g ASM home even though the 
ocssd.bin process is running out of 11g ASM home. In our testing it looks like 
it is working. I would like to know from support and configuration point of 
view whether this i ok.
In other words does ocssd.bin started from 11gASM home support diskgroups 
mounted by 10g ASM instance.

Regards,
Sanjeev.
