To Change vmnics numbering in esxi 5.5

Recently i have prepared esxi 5.5 host ,which came as embedded image with IBM x3850 x5 server

 and observed vmnic numbering is different as showing for other host in cluster and due to that it is not allowing to apply the host profile ?

how can we resolve it ?

is it fine if we change the vmnic numbering and if yes,how can we do that ?

any other way if can be done from host profile to be applied ?

and how can we run repair for  this embedded esxi 5.5 or if re installation can be done some how ?

seems it was done due to pci slot interchanged on esxi host and  hence numbering is different  , so what could be done to get same config as i have  in other host in my cluster.?
and can we check for pci slots numbering with nics attached using command line.?

The only method to change the vmnic numbering is to edit the configuration files on the host directly, via the console or remotely via SSH.

Thanks Andrew.

can we try for re-installation of this embedded esxi  5.5 ?

as i am not able to look for any options while booting with embedded drive ?

 and  how can we we check for  pci slots with diff vmnics using command line on my host ?
Andrew Hancock (VMware vExpert / EE MVE^2)VMware and Virtualization ConsultantCommented:
A re-installation is not going to make any difference, if you want the vmnic numbering to be the same as other hosts, you will need to list the PCI IDs, and alter the configuration files.

this command will show you the PCI information

Tried with esx.conf update no luck.

please advise, if we can try for re installation.but how as due to embedded it is booting with that embedded image,no option for repair and re installation ?
Andrew Hancock (VMware vExpert / EE MVE^2)VMware and Virtualization ConsultantCommented:
You've not edited the configuration file correctly. We have done this many times with success, if the PCI numbers are known, and these are replaced against the vmnic reference name in the file.

You have nothing to lose by trying a re-installation.

There is nothing special about embedded, it means it has an internal SD card or USB flash drive where the ESXi software has been installed.

only way i found is to involve vendor and to reburn the embeded as no luck even after installation done using iso image
Andrew Hancock (VMware vExpert / EE MVE^2)VMware and Virtualization ConsultantCommented:
The installer will just use the PCI slot locations and may the vmnic numbers, if you do not want them in that order, they will have to be manually altered.

They may edit the esx.conf file for you, if they have the skills, although this is an unsupported activity.

You *should* always ensure the latest firmware before deployment of any OS! especially ESXi, and ensure firmware is up to date, and nic drivers are up to date!
