General Web Tools Limitations

Licenses If you remove the Web license after Web Tools application windows are
opened, Web Tools displays the Web license missing dialog. From this point
on, Web Tools behavior will be undefined if you continue with other
operations after removing the license.
Workaround: Close and relaunch the browser.
Loss of Connection 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 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 will automatically try 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, the 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 Webtools.
You need to close Switch Explorer and relaunch Web Tools to reopen the
connection.
Performance Monitor If the Web browser crashes or the Performance Monitor license is lost while
the Performance Monitor module 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.
Performance Monitor For SCSI Read, Write, or Read/Write on a LUN per Port graphs, Fabric OS
v4.1.0 (and later 4.x versions) allows you to enable only two bytes or less for
the LUN value mask setting. Fabric OS v3.1 (and later 3.x versions) allows up
to three bytes. Web Tools displays an error message if you exceed this limit.
Workaround: There is no workaround.
