Publication Date:  2012-07-25 Views:  61 Downloads:  0
Issue Description
One day, engineer did the inspection for whole Network by the Inspector tools,found out a Critical problem for many NEs (attached):
 OptiX OSN 3500   Others_State_Checking  Checking task status of control board  Important  008_JKT_BRTO_00(9-2008) " Abnormal.
  VOS_Entry    SUSPEND  70 "
The version of NE is 5.21.19.22 and the NE does not enable the ASON function.
Alarm Information
 Abnormal.
  VOS_Entry    SUSPEND  70 
Handling Process
1.Check the inspector log, and find out the logs of  all tasks information:
<Message cmd = ":sys-get-alltaskinfo;">
 SYSTEM-TASK-LIST                                    
               Task-Name        Mod-Name         State          Prio  
               tClrDog                                           DELAY           5                       
               tChkAux                                          DELAY         100                     
               VOS_Entry                                     SUSPEND    70                      
               OSPCLK                                          DELAY           1                       
               tVosClearDog                                 DELAY         250    
               tIonNbsSch               ION                SUSPEND  70   
 ....
 Total records :182 
  2. We find there are two tasks have been suspended:  
         VOS_Entry  &  IonNbsSch
  The VOS_Entry task is a an entry task for the SCC software program,so it is only running at the begining of SCC startup. It would be suspended after SCC is 
running normal.
   The IonNbsSch is only running at NEs which enable the ASON fuction.
 
3. It is normal that these two tasks are suspended.
     If  other task is also suspended, we need investigate.
Root Cause
This item "Checking task status of control board"  is checking  all the task running on the SCC board.
If the state of task is SUSPEND, the abnormal event would be reported by the inspector. 
Suggestions

For the running equipment, the VOS_Entry should be suspended always. It is normal and no need do any operation. If  other task is also suspended except VOS_Entry  &  IonNbsSch, we need investigate.
