**************> QUESTION level 1 --> level 2 SPECIALIST <**************         
Question:                                                                       
Environment: RISC/6000 model F30, AIX 4.1.4, X25 Link,                          
             Communication Server for AIX 4.1                                   
             (X.25 Coprocessor/1 ISA adapter)                                   
RISC/6000 is connected to a remote system over a switched                       
X.25 line to run a LU6.2 application.                                           
We are not able to start the linkstation and tried to                           
activate the x25mon to locate the problem:                                      
when starting "x25mon -s -p -n x25s0" we get the following                      
message: x25mon: cannot retrieve data from ODM : 23                             
From a device point of view everything seems OK:                                
- adapter available                                                             
- port available                                                                
- COMIO available                                                              
- dlc available                                                                 
Any idea on what causes our problem?                                            
Thanks in adavance, best regards, Marina.

RESPONSE:                                                                       
                                                                                
In review of this item, I have found no history of this error for               
running x25mon.  From the general text of it, it appears that                  
entries in the ODM database for the sx25a0 necessary for x25mon are             
missing.  I would remove and build you configuration from X.25 from             
scratch.  Make sure you save your previous configuration information.           
Stop all activity over the X.25 link such as SNA, COMIO/NPI                     
applications, and TCP/IP interfaces. Do the following.                          
                                                                                
rmdev -l xs0 -d (if you have xs0)                                               
rmdev -l sx25a0 -d (and other ports if your are using portmaster)               
rmdev -l twd0 -d                                                                
rmdev -l ampx0 -d (amp0 for portmaster)                                         
cfgmgr                                                                          
Add twd0 and the port back                                                      
                                                                                
Thank you for using AIX Support services.
