So my upgrade from esxi 5.0 U3 to esxi 5.5 did work different like johnsonclaires guide 1 + 2 like described 3.) for i in `hostips`; do echo $i && ssh root@$i "esxcli software vib install -d /FILEPATH TO OFFLINE BUNDLE"; done 4.) like described 5.) Set host in maintaince mode 6.) Reboot esxi server 7.) After reboot reconnect esxi server 8.) CVM is listed as unkown and unkown1 vm. The local nfs datastore is not available 9.) Read on the Nutanix Operation Guide 3.5 and fixed it 10.) ls -ld /altbootbank/Nutanix /altbootbank/svmboot.tar.gzIf /altbootbank/Nutanix or /altbootbank/svmboot.tar.gzexist, move it to /bootbank. Otherwise,proceed to the next step.mv /altbootbank/Nutanix /bootbankmv /altbootbank/svmboot.tar.gz /bootbankc.

The nuxtnaix server 3451 uses two Intel Network cards 82599eb . This card has only 10000 Gbit full duplex option in GUI and on command line. Does this mean, the cisco swith has to be configured also 10000 Gbit full fuplex and not autonegotiate? http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1004089 On the other side when autonegotiation is disabled option are lost. http://etherealmind.com/ethernet-autonegotiation-works-why-how-standard-should-be-set/ Disabling autonegotiation can result in physical links issues going undetected. The Fast Link Pule process does some testing for the physical link properties as well as negotiation on several Ethernet properties.
