Mounting AIX 4.1 CD on a 3.2.5 system

ITEM: RTA000064099



Mounting a CD (mount /cdrom) with AIX 4.1 on a CD drive connected               
to a AIX 3.2.5 system caused the following problems:                            
                                                                                
¢ cd /cdrom                     Works ok                                        
¢ ls                            Lists the filenames on the CD, ok               
¢ ls -l (or any other option)   The following error-message occur               
                                for each file on the CD                         
                                                                                
ls:0653-341 The file ...filename... does not exist.                             
                                                                                
The 3.2.5-system should "see" the filesystem on the CD as any                   
filesystem ? Listing the files (ls -l) when the CD is mounted on                
the 4.1, the ls command works ok.                                               
                                                                                
                                                                               
                                                                                
ANSWER                                                                          
   I was not able to reproduce this situation.  Let me explain a test           
   I did.  I mounted the Infoexplorer CD on a c10 at 4.1.1.  Then               
   exported the cdrom filesystem via NFS.  Then on a 320 at 3.2.5               
   mounted the cdrom filesystem from the c10.  With this setup                  
   I was able to list all the files on either the server or the                 
   NFS client.  Are you at AIX 4.1.1?  If not,                                  
   try the same steps at the 4.1.1 level of code.                               
                                                                                
My problem where the opposite of what you tested. The AIX-CD                    
(AIX 4.1.1.1 for Clients) where mounted on a 3.2.5-system and                   
the error occured when listing the CD-ROM files on the 3.2.5-system.            
It works ok when mounting the CD on a 4.1.1.0-system.                           
                                                                               
                                                                                
ANSWER                                                                          
Response:                                                                       
                                                                                
Today, I reproduced the error that was encountered.  I mounted the 4.1.1        
for Clients CD on an AIX 3.2.5 system.  I was able to perform the 'ls'          
command that you executed.  However, I was not able to perform the 'ls-l'       
command to list the files located on the CD-ROM.  To explore the problem        
even further, I mounted the 4.1.1 for Clients CD on an AIX 4.1.1 system.        
This time the 'ls' command and the 'ls -l' command both executed                
correctly.  Similarly, I did an NFS export from the AIX 3.2.5 to the            
AIX 4.1.1 system.  The problem did occur.  I also looked and this has           
not been reported as a defect in the past.  I would have like to test           
this with a different AIX 4.1 CD, such as InfoExplorer but did not have         
one available.                                                                 
                                                                                
If you want to pursue this as a defect please contact your local Defect         
Center.                                                                         
                                                                                
Thank you.
