14. 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
Table 14-1 General Situations
Situation Resolution
After installing and starting the OneCommand
Manager application, the status bar shows
“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 application 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 is downloaded
automatically. This is 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, or that a 16 Gb/s adapter is not attempting to
connect to a 1, or 2 Gb/s device. Only 2 Gb/s, 4 Gb/s, and 8 Gb/s
devices are supported on 8 Gb/s adapters and only 4 Gb/s, 8 Gb/s,
and 16 Gb/s devices are supported on 16 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.
