Hi

No, I ralize now that is was a bit short on information.
As I said, I wanted to create a second diskgroup and did what I should
first with
/etc/init.d/oracleasm createdisk

and after it was marked as a candidate i started dbca to ad it to the
asm, but instead of adding a diskgroup I added the disk to the
existing group. When I hit ok button it gave me an ora error
(ORA-15075 disk(s) are not visible cluster-wide) and I realized it was
wrong action I had taken and that I only could se the disk from first
node in cluster, I then tried to remove the disk from the group which
I so far haven't managed.

unfortunately, still on 10.2.0.1...

Hi,

It is not clear from your mail what is the exact operation which has led to
this issue.
Are there any errors in the alert.log of the ASM instance?

You can try to force a rebalance on this node and check if it helps

alter diskgroup ORADATA1 rebalance power 11;

Also I hope u are on 10.2.0.2

Hi

In our RAC environment (oracle 10.2 on linux, storage is in ASM, 2
node cluster) I should add a second diskgroup so that we could run
some bigger tests but instead of creating a new diskgroup I added it
to the existing group. Now I dont know how to remove it from the
group.

At the moment only one node is working , probably due to this error i made.

from sqlplus i get:
system@msrac1> select name, state from v$asm_disk;

NAME STATE
------------------------------ --------
ORADATA1 NORMAL


but when looking in EM I also have a second disk ORADATA2 in state
FORCING, it shows 100% used but should have no data in it.
