The following table lists Java application errors:
Table 8-2 Java application errors
Error condition Probable cause / Recommended action 1 The page is not displayed because of an
invalid syntax error. Enter the URL of the desired SVP in the Trusted sites section of the Internet Options dialog box.
2 Storage Navigator does not start even with repeated attempts.
• Close all the web browser windows and then clear the Java and web browser cache.
• Use the Task Manager to check for ‘hung” or duplicate processes.
3 A network error occurred when you log in to
Storage Navigator. Close all dialog boxes and log in to the Storage Navigator again. If the same error occurs, check the network environment.
Error condition Probable cause / recommended action 1 When you click the Storage Navigator menu,
the system does not respond. One minute later, application error (20020,10800) occurs.
The pop-up blocker function of your web browser might restrict Storage Navigator. If the problem still continues after you perform the operation multiple times, perform one or both of the following actions:
• Disable the pop-up blocker function of your web browser.
• Disable the pop-up blocker function of any browser plug-in/add-on.
If neither of the above can be performed in Internet Explorer, you can open the window by clicking the Storage Navigator menu while holding down the Ctrl key.
Another possible cause is that a Java application was not allowed to start. If a message appears and asks if you want to run an application, click Run.
If none of the above actions solve the problem, reinstall the JRE.
2 When you click the Storage Navigator menu, a message appears asking you to download the file SJsvlSNStartServlet.do or
SJsvlAppStartServlet.do. One minute later, the application error (20020,10800) occurs.
The possible causes are that the JRE is not installed in the Storage Navigator computer, the JRE installation failed, or the JRE add-on is disabled on the web browser. Cancel the message, and install the JRE. If the JRE is already installed, reinstall it.
3 • The application errors (20020, 10800 and 10,6027) occur when you click the Storage Navigator menu.
• The application error (10,6027) occurs and Storage Navigator terminates when you click the Storage Navigator menu.
If the problem continues after you perform the operation multiple times, the probable causes are as follows:
• Java on the Storage Navigator web client might have failed to start due to timeout.
Close all other applications and perform the Storage Navigator operation again.
• The version of Storage Navigator installed on the client computer might not match the SVP version. Close all the windows of your web browser and then clear the Java and web browser cache.
• The Storage Navigator computer might have entered standby or hibernate mode. Restart Storage Navigator computer.
• If a proxy server is used for network
connections, the proxy cache may be storing the older version of the program. If the problem continues after you clear the Java and web browser caches, contact your network administrator.
• The network connection between the SVP and the Storage Navigator computer might be blocked by a firewall or some kind of device.
Check the firewall settings and contact your network administrator.
If none of the above actions solve the problem, save the dump file, the Java trace file and the log file on the Storage Navigator computer, and report to the Hitachi Data Systems Support Center. Then restart the Storage Navigator.
4 When you click the Storage Navigator menu, the system does not respond.
If the problem continues after you perform the operation multiple times, close all the Storage Navigator windows and clear the Java and web browser caches.
5 The application error (1,7050) occurs when
you click the Storage Navigator menu. The version of Storage Navigator installed on the Storage Navigator computer might not match the SVP version. Close all the windows of your web browser and then clear the Java and web browser caches.
