Before upgrading the DNCS, run the Doctor report using the instructions provided 
in the DBDS Utilities Version 6.1 Installation Instructions and DNCS Utilities User’s 
Guide (part number 4020695). The Doctor report provides key system configuration 
data that might be useful before you begin the upgrade process. 

Notes:   

 

On a typical system, the Doctor report takes about 10 minutes to run. 

 

Call Cisco Services if the Doctor report indicates that the database requires 
additional data space or temporary space. 

 

When you analyze the output of the Doctor report, be certain that no disk partition is 
at over 85 percent capacity. Call Cisco Services if the Doctor report reveals that a 
disk partition is over 85 percent capacity. 

Also analyze the output of the Doctor report to verify that the inband 
SI_INSERT_RATE is not greater than 0 (zero). If the inband SI_INSERT_RATE is 
greater than 0 (zero), refer to Recommendations for Setting System Information to Out-of-
Band (part number 738143), and follow the procedures provided to disable inband SI. 

Note: If the inband SI is disabled, then the SI_INSERT_RATE is 0. 

Important!  Do not go to the next procedure until you have completed running and 
analyzing the Doctor report and correcting any problems it reports.
