General Web Tools limitations 18 TABLE 21 Area Web Tools limitations (Continued) Details Loss of Connection Non-FIPS secure mode HTTPS Out of Memory Errors Performance Monitor Performance Monitor Refresh option in browsers Refresh option in browsers Refresh option in browsers Occasionally, you might see the following message when you try to retrieve data from the switch or send a request to the switch: Switch Status Checking The switch is not currently accessible. The dialog box title may vary, because it indicates which module is having the problem. This is caused by the loss of HTTP connection with the switch, due to a variety of possible problems. Web Tools automatically tries to regain the connection. While Web Tools is trying to regain the connection, check if your Ethernet connection is still functioning. If the problem is not with the Ethernet connection, wait for Web Tools to recover the connection and display the following message: "You will have to resubmit your request after closing this message." If the temporary switch connection loss is caused by switch hot code load, or other similar operation, Switch Explorer you are currently running can be downloaded from a different firmware version than the new one. In this case the following message displays: "Switch connection is restored. The firmware version you are running is not in sync with the version currently on switch. Close your browser and re-launch Web Tools." You need to close Switch Explorer and relaunch Web Tools to reopen the connection. HTTPS supports only TLSv1 and SSLv3 protocols with !DH:HIGH:-MD5 cipher in non-fips mode. These options must be enabled in your internet browser. If you are managing fabrics with more than ten switches or more than 1000 ports, or if you are using the iSCSI Gateway module extensively, you might encounter out-of-memory errors such as the following: java.lang.OutOfMemoryError: Java heap space To avoid this problem, increase the default heap size in the Java Control Panel. Refer to "Java plug-in configuration" on page 8 for instructions. If the Web browser crashes or the Performance Monitor license is lost while the Performance Monitoring window is running, some of the Performance Monitor resources owned by Web Tools might not be cleaned up correctly. Workaround: You might need to use the CLI to manually delete these counters. For example, if you detect Web Tools owned resources (using perfshoweemonitor), but you have verified that no Web users are actually using them, use the perfdeleemonitor or perfcleareemonitor command to free the resources. The Switch Throughput Utilization, Switch Percent Utilization, and Port Snapshot Error graphs displays the faulty/powered off slot node in the Y-Axis of the graph. Workaround: Launch any port selection dialog box and load the graphs accordingly. When a pop-up window requesting a user response is pushed into the background and a refresh is requested, a fatal Internet Explorer error might occur. Workaround: Restart the browser. Web Tools must be restarted when the Ethernet IP address is changed using the NetworkConfig View command. Web Tools appears to hang if it is not restarted after this operation is executed. Workaround: Restart the browser. If you change the switch name or domain ID using the CLI after the Web Tools Switch Administration window has started, the new switch name or domain ID is not updated on the header of the Switch Administration page. Clicking the Refresh button does not fix the problem. Workaround: Click the Switch tab and the Switch Administration header updates. Web Tools Administrator's Guide 231 53-1002756-01
