Table 14 Advanced Web Tools limitations Problem area Browser Browser Firmware download HTTP timeout Details The Fabric Watch, Switch Admin, HA, Name Server, and Zone Admin modules are separate applets embedded in HTML pages. The successful launch of an applet depends on whether the browser can successfully load the HTML page. Occasionally, you will see a blank browser window with the message loading pages... that is stuck. This is likely caused by a sudden loss of the switch web server (either by normal HA failover, reboot, or other causes). Workaround: If the Fabric Watch, Switch Admin, HA, Name Server, or Zone Admin modules hang, close this window and relaunch the module. An Advanced Web Tools browser window might stop responding following an HA failover immediately after a zoning configuration was enabled or disabled. It is likely that the web daemon was terminated by the HA failover before the HTTP request was sent back. Workaround: If one of the Advanced Web Tools modules is hanging, close the window and relaunch the module. If the module is locked, shut down and relaunch the Advanced Web Tools application. There are multiple phases to firmware download and activation. When Advanced Web Tools reports that firmware download has completed successfully, this indicates that a basic sanity check, package retrieval, package unloading, and verification was successful. Advanced Web Tools forces a full package installation. A reboot is required to activate the newly downloaded firmware. This reboot is performed automatically. Although Advanced Web Tools screens continue to be visible during the reboot, they are not available. Wait approximately 10 minutes to ensure that all the application windows have been restored. If Advanced Web Tools fails to respond after 20 minutes, you might need to close all Advanced Web Tools applications windows and restart them or to contact your system administrator for network assistance. The Advanced Web Tools loss of network connectivity during a failover or reboot (initiated though the firmwaredownload command) varies for different configurations: • Core Switch 2/64, SAN Director 2/128, and 4/256 SAN Director: Loss of network connectivity is up to 5 minutes if the power-on self-test (POST) is disabled. If POST is enabled, the loss of network connectivity can exceed 5 minutes. • 4/8 SAN Switch, 4/16 SAN Switch, SAN Switch 2/8V, SAN Switch 2/16V, SAN Switch 2/32, 4Gb SAN Switch for HP p-Class BladeSystem, and SAN Switch 4/32: Loss of network connectivity is up to 1 minute if POST is disabled. If POST is enabled, the loss of network connectivity can exceed 1 minute. Occasionally, you might see the following message when you try to get data from a switch or to send a request to the switch: Failed to get switch response. Please verify the status of your last operation and try again if necessary. This indicates that an HTTP request did not get a response. The request was sent to the switch, but the connection was down, probably caused by a temporary loss of the web server on the switch. Due to the nature of an HTTP connection, Advanced Web Tools reports this error after a 90-second default timeout. In this case, verify the status of your last request, using telnet to check related status, or click the Refresh button from the Advanced Web Tools application you were working on to retrieve related data. If your request did not get through to the switch, resubmit it. Executing a refresh from Advanced Web Tools retrieves a copy of switch data at that moment; the data you entered can be lost if it was not already committed to the switch. 142 Limitations
