# This script will connect to UCS Manager, collect IPMI information #
# for the provisioned blades, and update the appropriate IPMI       #
# information on the ESX hosts.  The script can also be run to      #
# update the IPMI information if a service profile is moved to a    #
# different blade.                                                  #

### Where the fun begins
### Lets log in to vCenter and UCS
$vCenter = Connect-VIServer -server $vCenterUrl -user $vCenterUser -password $vCenterPassword
$cookie = ucs_login $ucsUser $ucsPassword $ucsUrl

### Grabbing ESX hosts from vCenter
Write-Host "Getting ESX Hosts from vCenter"
$esxhosts = get_esx_hosts $vCenter

### Get the IPMI settings from UCS and update ESX hosts with information
Write-Host "Getting IPMI Settings from UCS and configuring ESX"
foreach ($h in $esxhosts) {
    $h = get_host_ipmi $h $ucsUrl $cookie
    set_host_ipmi $h $vCenter
}

### Fun as ended, time to log out.
Write-Host "Logging out of UCS"
$outStatus = ucs_logout $ucsUrl $cookie
Write-Host $outStatus
Write-Host "Logging out of vCenter"
Disconnect-VIServer -server $server -confirm:$false
