Start or stop ESXi services using PowerCLI

by Mar 3, 2017PowerCLI, VMware, vSphere

Start the ssh service on all hosts:

Get-VMHost | Foreach {
   Start-VMHostService -HostService ($_ | Get-VMHostService | Where { $_.Key -eq "TSM-SSH"} )
}

Thanks to Alan Renouf at virtu-al.net, where I found this snippet: http://www.virtu-al.net/2010/11/23/enabling-esx-ssh-via-powercli/

If you want to start the ssh service on a single host, change ESXiHostName to your ESXi FQDN:

Get-VMHost -Name ESXiHostName | Foreach {
   Start-VMHostService -HostService ( $_ | Get-VMHostService | Where { $_.Key -eq "TSM-SSH" } )
}

If you want to stop the ssh service on all hosts:

Get-VMHost | Foreach {
   Stop-VMHostService -HostService ($_ | Get-VMHostService | Where { $_.Key -eq "TSM-SSH"} )
}

If you have multiple cluster in vCenter, are connected to multiple vCenters, be sure to launch the command only to the necessary hosts:

  • Get-Cluster -Name ClusterName will filter to the specified Cluster
  • Get-VMHost -Name ESXiHostName will filter to the specified ESXi
  • Get-VMHost -Server vCenterServerName will filter to the specified vCenter server
Get-Cluster -Name ClusterName | Get-VMHost -Name ESXiHostName -Server vCenterServerName | Foreach {
   Stop-VMHostService -HostService ($_ | Get-VMHostService | Where { $_.Key -eq "TSM-SSH"} )
}

These are other services I frequently use:

  • DCUI (Direct Console UI)
  • lwsmd (Active Directory Service)
  • ntpd (NTP Daemon)
  • sfcbd-watchdog (CIM Server)
  • snmpd (SNMP Server)
  • TSM (ESXi Shell)
  • TSM-SSH (SSH)
  • vmsyslogd (Syslog Server)
  • vmware-fdm (vSphere High Availability Agent)
  • vpxa (VMware vCenter Agent)
  • xorg (X.Org Server)

There are other services available but I have never used them in this context (yet):

  • lbtd (Load-Based Teaming Daemon)
  • pcscd (PC/SC Smart Card Daemon)
  • vprobed (VProbe Daemon)

Change the startup policy for a service:

  • Automatic: Start automatically if any ports are open, and stop when all ports are closed
  • On: Start and stop with host
  • Off: Start and stop manually
get-vmhost | Foreach {Set-VMHostService -HostService ($_ | Get-VMHostService | where {$_.key -eq "tsm-ssh"}) -policy On}
