Troubleshooting
There are several circumstances in which your system may operate in an unexpected manner. The
Troubleshooting section explains many of these circumstances and offers one or more workarounds for
each situation.
General Situations

Situation
Resolution
After installing and starting OneCommand
Manager, the status bar says "Initializing
discovery engine...", but after waiting for
awhile, nothing is displayed in the discovery-
tree.
It is possible the discovery server was not installed properly and
therefore is not running. Try uninstalling and re-installing the
OneCommand Manager package.
The Web Launch interface cannot be started.
When you attempt to start the OneCommand
Manager application Web Launch Interface
client interface, you receive an error
message stating "Unable to launch
OneCommand."
If the JRE/Web Start version present on your system does not
meet the minimum required by the OneCommand Manager
application, a temporary copy of the correct Web Start version
will be downloaded automatically. This will be used to open the
OneCommand Manager application Web Launch Interface
client interface and is then discarded once you terminate your
session. On some systems, however, security settings or other
factors may prevent this download from completing
successfully, resulting in this error.
To fix the problem, manually update the JRE on your system to
the version required by the OneCommand Manager application.
The FC link fails to come up.
Verify that an 8 Gb/s adapter is not attempting to connect to a 1
Gb/s device. Only 2 Gb/s, 4 Gb/s and 8 Gb/s devices are
supported on 8 Gb/s adapters.
The other utilities install, but the
OneCommand Manager application does
not.
You have attempted to install the utilities before installing the
Emulex driver.
Perform the installation tasks in the following order:
1. Install the Emulex driver (see the Installation section of the
driver manual).
2. Install the utilities (see the Installation section of the driver
manual).
When attempting to start the OneCommand
Manager application, the Web browser
displays “Emulex Corporation OneCommand
Demo of OneCommand WebStart web
n.n.n.n...”
The document caching mechanism sometimes behaves
erratically if more than one version of Java Runtime is installed
on the browser client. There are two workarounds for this
problem:
• Exit the browser and restart it. The OneCommand Manager
application Web Launch Interface starts successfully.
• Uninstall all non-essential versions of the Java Runtime. The
OneCommand Manager application Web Launch Interface
requires that only a single version of the Java Runtime be
installed on the browser client. This single version must be
Java 6.0 or later for all platforms.
