powercli
just rox. we at dell emc today had an issue where we had
3 UCS
domains and client wanted all the 110+ blades to be distributed across these 3
domains. IP addresses were not in range. We use a custom linux virtual machine
which install esxi on UCS with proper vmkernel networking. However that is not
designed for such scenarios. So the ip addresses how this esxi deployer
assigned was not at all matching what the customer wanted. We thought by the
time our storage guys assign boot luns then i could figure out a script to
change the ip addresses of all these 110+ blades. I even took my buddy
gowtham's data center without asking him and played around with it. It worked
for the 8 blades that we had. I used plink to deliver the esxcli command as
mentioned by duncan epping . Needless to
say what worked on a small solution didnt work on this one for some reason. I
was using a csv file to input the
old ip
new ip
username
password
vmkernel (it
was vmk0)
but it
failed and we as a team shared all 15 blades per head and changed the ip
addresses manually. We did not have much time to play. I just reached home and
so far i have this.
connect to the esxi host first

Now change the ip address

That true is really encouraging. I connected to the new changed ip address now.

Yes, you can change any vmkernel ip address like this but i am trying to figure out an esxcli -v2 version of it. Nay sayers listen to this. If you do not know how to do it then it doesn't mean it can't be done.
Now here is the esxcli -v2 version.
PS C:\WINDOWS\system32> $esxcli = Get-VMHost | Get-EsxCli -v2
$esxcliset = $esxcli.network.ip.interface.ipv4.set
$args = $esxcliset.CreateArgs()
$args.interfacename = 'vmk0'
$args.type = 'static'
$args.ipv4 = '192.168.248.136'
$args.netmask = '255.255.255.0'
$esxcliset.Invoke($args)
true
PS C:\WINDOWS\system32> disconnect-viserver * -confirm:$false
Connect-VIServer 192.168.248.136 -User root -Password 'vmware1'
