Come on Oracle, I know there are 3 nodes Firewire out there, and there is must be a way to debug/trace the problem. So far I am disappointed by the response (or lack of it) by Oracle on this thread.
Regards.

On one node, it is:
[root at melclul14 root]# dmesg | grep sbp2
ieee1394: sbp2: Query logins to SBP-2 device successful
ieee1394: sbp2: Maximum concurrent logins supported: 4
ieee1394: sbp2: Number of active logins: 2
ieee1394: sbp2: Logged into SBP-2 device
ieee1394: sbp2: Node[04:1023]: Max speed [S400] - Max payload [2048]
ieee1394: sbp2: Query logins to SBP-2 device successful
ieee1394: sbp2: Maximum concurrent logins supported: 4
ieee1394: sbp2: Number of active logins: 1
ieee1394: sbp2: Logged into SBP-2 device
ieee1394: sbp2: Node[05:1023]: Max speed [S400] - Max payload [2048]
[root at melclul14 root]#
On another it is:
ieee1394: sbp2: Bus reset in progress - rejecting command
...... last line repeat many times......
ieee1394: sbp2: Bus reset in progress - rejecting command
ieee1394: sbp2: Reconnected to SBP-2 device
ieee1394: sbp2: Node[05:1023]: Max speed [S400] - Max payload [2048]
All has the same hardware. Does this mean anything? I am sure the one rejecting the command returned the same as another node, and I bet it will be OK if I re-boot it, and most importantly the Oracle RDBMS and CRS are running OK on both nodes.
Cheers.

More than Likely its your SAN which is causing the problem can you send
the output of the following command.
dmesg | grep sbp2

Tried it and still the same, only two out of the four nodes can run.
Any more ideas please?
Thanks in advance.

Han,
You do it as below.
Login as Oracle
su root
1) Shut down oracle database
srvctl stop database -d dubp
2) Shut down all nodes but one node
3) Execute crsctl to modify the misscount:
% $ORA_CRS_HOME/bin/crsctl set css misscount 120
4) Reboot the node where adjustment was made
5) Start all other nodes shutdown in step 2
Regards,
Khurram

Thanks a lot for the suggestion. My storage supports maximum 4
concurrent logins.
Can you tell me how to change the css timeout please?
Thanks in advance, and regards.

That's not Oracle Limitation, That's shared storage limitation, do you
know how many concurrent logins your shared storage supports. You can
check that by following command.
dmesg | grep sbp2
The output should be like this----
ieee1394: sbp2: Query logins to SBP-2 device successful
ieee1394: sbp2: Maximum concurrent logins supported: 2
ieee1394: sbp2: Number of active logins: 1
ieee1394: sbp2: Logged into SBP-2 device
ieee1394: sbp2: Node[01:1023]: Max speed [S400] - Max payload [2048]
If this command shows that your storage supports upto 4 users then you
may have to increase the css timeout to 120. It might resolve the
problem.
Regards,
Khurram

Hi all,
I replaced our Firewire cards and all 4 nodes are running OK. I
installed CRS on all 4 nodes fine. I then installed Oracle RDBMS on all
4 nodes OK. Next, I used DBCA to create a database, it almost
succussed. It hangs at the last step when try to startup the instance.
To debug it, I re-boot all 4 nodes, and manually run SQL*Plus, it hangs
as well. (I double checked the datafiles are created fine on the shared
disk)
In the /var/log/message, it has message like:
May 17 11:46:03 melclul11 kernel: ocfs: Removing melclul12 (node 0) from
clustered device (8,46)
I thought it might an Oracle limitation. So I disable the crs on two
nodes, and YES, I can startup my database fine.
Now, all 4 nodes are running, only two has crs enabled, and a database
is running on these two nodes. It is quite clear to me that this is an
Oracle limitation, Oracle only allow 2 nodes on Firewire.
My question is, is this limitation configurable? and How?
Thanks in advance.
