Element Manager Problems and Solutions
Problem
Meaning and Solution
HTML Login page does not appear.
The browser error message: Could not reach the destination IP address or a
page not
found
error or a DNS error.
Either the SAN Router cannot be reached or the embedded web server in the SAN
Router is not active. Try a ping request to the SAN Router to test connectivity. If the
ping succeeds, it is likely that the embedded web server is down. The SAN Router may
need to be rebooted to restart the web server.
If the ping is not successful, there are several possible causes:
•
A network problem between the management station and the SAN Router.
Try
pinging other devices in the SAN Router's subnet.
•
Incorrect or missing DNS entry.
Try starting Element Manager with the SAN
Router's IP address instead of the host name.
•
Access blocked by an HTTP proxy.
Check the web browser settings to disable any
HTTP proxy.
•
Wrong IP address
. Use a console connection to verify the management port
address. If using inband management, such as managing through a FC/R port, use
a console connection to verify the SAN Router's inband address.
•
Missing default gateway or static route.
If the management station is not in the
same subnet as the SAN Router's management port or inband address, then the
SAN Router requires a default gateway or static route. Use a console connection to
verify or add a default gateway or static route.
• If the Management port hangs, use the CLI command
reset mgmt
to reset the
management port
Login applet within the HTML Login page
does not appear or takes a long time to
appear.
The HTML Login page successfully loads but an empty gray box appears in the center
of this page. The field to enter the password does not display. Sometimes a message
appears in the upper left corner of the gray box stating that a jar file is being
downloaded to the browsers.
If the browser has been configured to use an HTTP proxy, there could be a lengthy
delay (taking many minutes) to download the Element Manager java files from the
SAN Router to the browsers.
In Internet Explorer, use Tools>Internet Options>Connections>LAN to cancel all the
selections. This will disable the proxy. To disable the proxy only for specific SAN
Routers, click the
Advanced
button. Enter individual switch addresses or hostnames in
the
Exceptions
box. (Using the ‘*’ wildcard does not always work.)
In Netscape 6, use Edit>Preferences> Advanced>Proxies to disable the proxy. To
disable the proxy for only specific SAN Routers, enter the SAN Router inband IP
addresses or hostnames in the
No Proxy for:
box.
