Abstract

LIC-DISK-OTHER -RC1310 MSGCPDB8E3 ERROR2 VARY ON SOURCE IASP
AFTER SUCCESSFUL CFGGEOMIR

Error Description

When configuring geographic mirror (CFGGEOMIR) and there are    
multiple paths to the disks and more than one disk              
controller is involved, attempting to vary on the source IASP  
after a successful CFGGEOMIR could result in CPDB8E3 with error
2 and reason code 1310 indicating that there is an error on the
mirror copy and the disk unit is missing from the configuration.
                                                               
It was discovered that an internal cleanup step was missed. A  
code update will occur to ensure that cleanup is performed      
correctly and the result will prevent the CPDB8E3 from          
occurring in this scenario.                                    
                                                               
Work around: End the mirror node from the cluster, IPL the      
mirror node, restart cluster and attempt to vary on the source  
IASP again.                                                    

Problem Summary

Please see the ERROR DESCRIPTION section.                      

Problem Conclusion

At one point, several devices were in a format corrupt state and
we had our xMediaError flag turned on. After the disks were    
initialized, the xMediaError flag was turned off on the primary
path, but not on the secondary path, thus preventing the iASP  
from varying on. A change will be made to ensure the            
xMediaError flag is reset on all paths after a disk is          
successfully formatted.
