Update SSH Host Keys

For each ESXi host that you rebuilt as part of recovering the management cluster or a VI cluster, you must update the SSH host keys in the
known_hosts
 file.
  1. Enable SSH on all Hosts in the Cluster by running the following powershell commands
    $restoredVcenterFqdn = "sfo-m01-vc01.sfo.rainpole.io"
$restoredVcenterAdmin = "administrator@vsphere.local"
$restoredVcenterAdminPassword = "VMw@re1!"
$clusterName = "sfo-m01-cl01"
    Connect-VIServer -server $restoredVcenterFqdn -user $restoredVcenterAdmin -password $restoredVcenterAdminPassword
Get-Cluster -name $clusterName | Get-VMHost | Get-VMHostService | Where-Object {$_.label -eq "SSH"} | Start-VMHostService
Disconnect-VIServer -Server $global:DefaultVIServers -Force -Confirm:$false
  2. Refresh SDDC Manager SSH Keys.
    Replace x_x_x in the following commands with the relevant numbering for the version you downloaded.
    1. Copy the
      recovery_tools_python_x_x_x.zip
       file to the
      /tmp
       directory on the SDDC Manager virtual appliance by using a secure file copy utility as the vcf user.
    2. SSH to the SDDC Manager VM as the
      vcf
       user
    3. Switch to root and extract the
      recovery_tools_python_x_x_x.zip
      .
      su - 
cd /tmp
unzip recovery_tools_python_x_x_x.zip
cd /tmp/recovery_tools_python_x_x_x
    4. Run the following command to update all new SSH keys without the need to accept each individual key.
      "yes" | python refreshsshkeys.pyc
    5. Alternatively, run the following command to update all new SSH keys with the need to accept each individual key.
      python refreshsshkeys.pyc
  3. Run the following command to update host attributes without the need to accept each individual key. 
    python refreshhostattributes.pyc --domain=<domain-name>
