ESX(i) installations on HP systems require the HP NMI driverESX 4.1 instances on HP systems require the HP NMI driver to ensure proper handling of non-maskable interrupts (NMIs). The NMI driver ensures that NMIs are properly detected and logged. Without this driver, NMIs, which signal hardware faults, are ignored on HP systems with ESX.
Workaround: Download and install the NMI driver. The driver is available as an offline bundle from the HP Web site. Also, see KB 1021609.
If you need to update a driver on ESXi which is not yet available with vCenter UpdateManager, you need to login to vmax or vmay to update the driver.
1. Download the driver ISO on the VMWare site: http://downloads.vmware.com/d/info/datacenter_downloads/vmware_esxi/4#drivers_tools
2. Place the driver CD in the CD-ROM drive of the host where either the vSpher CLI package is installed or vMA is hosted.
3. Mount the driver CD: sudo mount /dev/cdrom /mnt
4. Navigate to /offline-bundle/ and locate the .zip file.
5. Run the vihostupdate command to install drivers using the offline bundle: vihostupdate –server XXX –install –bundle xxxxx.zip
6. Reboot the ESXi Host
7. Check if the patch has been installed: vihostupdate –server XXX –query
