Summaries and Symptoms

This patch fixes the following issues:

  • ESX might fail on some HP systems such as DL 980 G7 containing HP NC522SFP Dual Port 10GbE Gigabit Server Adapters and displays a message similar to loading 32.networking-drivers. This issue occurs when ESX starts the NetXen driver usually during the boot up of ESX hosts or during the installation of network drivers. This is dependent on some HP system configurations. After applying this patch, you can use NetXen NIC for Gigabit Ethernet connectivity with ESX hosts.

  • When using a NetXen 1G NX3031 or multiple 10G NX2031 devices, you might see an error message similar to the following on the service console of ESX 4.1 hosts after you upgrade from ESX 4.0: Out of Interrupt vectors. On ESX hosts, where NetXen 1G and NX2031 10G devices do not support NetQueue, the ESX host might run out of MSI-X interrupt vectors. This issue can render ESX hosts unbootable or other devices (such as storage devices) inaccessible.

Deployment Considerations

None beyond the required patch bundles and reboot information listed in the table above.

Patch Download and Installation

See the VMware vCenter Update Manager Administration Guide for instructions on using Update Manager to download and install patches to automatically update ESX 4.1 hosts.

To update ESX 4.1 hosts without using Update Manager, download the patch ZIP file from and install the bulletin by using esxupdate from the command line of the host. For more information, see the ESX 4.1 Patch Management Guide.
