Issue:

 

 

Unisphere may report the following issues if an IO Module or CNA commit operation does not complete successfully   

         
  •         SP shutting down, degraded (one or both), or in critical failure (one or both)     
  •      
  •         One SP may report rebooting     
  •      
  •         Storage Pool reports "An operation is in progress. Please wait"     
  •      
  •         When creating new objects the status is OK, Needs Attention / An operation is in progress.     
  •      
  •         IO Module commit from GUI or CLI is failing     
  •    
   
    To confirm where the issue resides, we can start my confirming if the array is still reporting any uncommitted ports use the following command.   
           uemcli /net/port/unc show -detail   
   
   
    If the commit is for an IO Module we can use the following command to confirm it is present.   
           uemcli /env/iomodule show -detail    
   
   
    Finally we can use the following log file to determine what the last reported step of the commit was. In the below log we can see that the IO module or CNA commits last completed task was the 16th of the total 22 tasks needed to complete the commit.
