after vmware 5.5 upgrade on dl380 g6, only see 3 nic's instead of 4

I had some time ago, updated a pair of HP DL-380 G6 hosts from 4.x to 5.5.  After the upgrade, everything has been working just fine, however, I seem to have lost one of my NIC's on each host.  Each server has 4 NIC's embedded in MB.

I can only see 3 on each host.

Update firmware, and then check for updated drivers.

I would also ensure, you have updated the latest firmware on the server, using the latest firmware DVD from HP. (there have been some known issue, with bad firmware with HP NICs in servers!)

Did you use the HP OEM version of ESXi 5.5, which includes the drivers for most of the HP network interfaces ?

otherwise if the servers and network interfaces are on the HCL, you will need to download and install the drivers separately.

So what are the network interface cards ?

Check the VMware Hardware Compatability Lists HCL here

The VMware Hardware Compatibility List is the detailed lists showing actual vendor devices that are either physically tested or are similar to the devices tested by VMware or VMware partners. Items on the list are tested with VMware products and are known to operate correctly.Devices which are not on the list may function, but will not be supported by VMware.

Yes, I had used the HP ESXi 5.5.0 1331820 installer at the time.  All of the NIC's are the same Broadcom NIC, but only 3 of them show and not the 4th.

Also, if I try to add a Network Adapter on either host, it shows up "blank", since it believes that all NIC's have been assigned and configured.

Will I have to do anything with the HP VMware drivers as well, prior to updating the firmware?
