URGENT!!! PROBLEMS WITH MODE3 FOR HACMP/6000.

ITEM: RTA000052747



QUESTION:                                                                       
I have two 570s configured for concurrent access using HACMP/6000. We           
have one 9333-501 disk drive subsystem being shared by both machines.           
The name of the volume group that is being shared by both systems is            
9333raw and it contains no filesystems. I can bring up HA on either             
machine separately but when I try to bring up HA for both machines              
to concurrently access volume group 9333raw, HA fails. The error msgs           
I get are as follows:                                                           
                                                                                
Right after HA runs "/usr/sbin/cluster/mode3 -c 9333raw" I get                  
mode3: ioctl (9333raw, DIOCONCURRENT): Bad address.                             
Also in looking at the /tmp/hacmp.out I get a lot of messages of                
" failed mode3 -c of 9333raw" and " /usr/sbin/cluster/utils/cl_mode3:           
failed mode3 -c 9333raw".                                                       
                                                                               
I am using HA 2.1 and right now I cannot start both machines in mode3           
because of this error.                                                          
                                                                                
Please let me know how I can fix this.

A: This problem was fixed by removing the shared VG from both machines,        
   removing the disks in the VG, removing the HA config, then re-adding         
   all of the information.
