Emulex 3.4 user manual Known Issues

Known Issues

The following issues have been reported at the time of publication. These issues may not have been verified or confirmed and may apply to another product, such as hardware.

•Emulex provides support for LightPulse® HBAs that are reprogrammed with World Wide Port Names (WWPNs) outside the typical Emulex range, such as Hewlett-Packard’s upcoming Virtual Connect for FC on the BladeSystem c-Class platform. In these environments, HBAnyware utility version 3.2 or later must be deployed across all servers on the SAN, and on any other management console used for TCP/IP access management.

•If there are multiple versions of the Java Runtime Environment (JRE) installed on your Internet Explorer client, then you may see the following text in the browser's main display window when you attempt to launch the HBAnyware utility via the browser:

If you verified that the HBAnyware Web Launch Services package is installed and is running on the target server, try one of these two workarounds:

•Exit the browser, then restart it. The HBAnyware utility launches successfully.

•Uninstall all non-essential versions of the JRE. HBAnyware Web Launch services require only a single version of the JRE be installed on the Windows browser client.

•On the VMware ESX Server, there is a known issue with the discovery-threads parameter. The range for this parameter should be 30 - 64 (decimal). The default is erroneously set to 1. Set this driver parameter to a valid value. If you do not, when you change any driver parameter value, the following error message may be displayed: “Driver Parameter ‘discovery-threads’ is not within the allowed range”.

•Centralized management of HBAs across VMware ESX servers must be limited to, at most, one HBAnyware client. This limitation applies to HBAnyware remote connectivity for both FC (in- band) and TCP/IP (out-of-band) management. The remote HBAnyware client configuration must be modified to disable automatic periodic polling of remote servers.

To disable automatic periodic polling of remote servers:

1.Start the HBAnyware utility.

2.From the Menu bar, click Discovery>Modify Settings. The HBA Discovery Proper- ties dialog box appears.

3.Define the discovery properties as follows:

•Discovery Server Startup area: This setting defaults to When the utility starts. Keep this default or if necessary select it.

•Refresh Rate, Fibre Channel area: Select the Manual Refresh (requires click- ing the discovery refresh button) checkbox.

•Refresh Rate, TCP/IP area: Select the Manual Refresh (requires clicking the discovery refresh button) checkbox.

•Expire Undiscovered HBA area: Select the Never Remove checkbox.

4.Click OK.

Emulex recommends that remote management of other Windows, Linux and Solaris servers take place in an environment separate from management of ESX servers. For example, other servers should exist in a separate zone so that the HBAnyware client that manage them does not automatically discover ESX servers.
