AddVirtualCenterServerChangeHostsToOK.ps1

更新日期: 2009年8月

適用於: Virtual Machine Manager 2008, Virtual Machine Manager 2008 R2, Virtual Machine Manager 2008 R2 SP1

When you add a VMware VirtualCenter server to System Center Virtual Machine Manager (VMM) 2008, VMM discovers all VMware ESX Server hosts and clusters that the VirtualCenter server is managing and adds the objects to VMM. You can add a VirtualCenter server to VMM by using the Add-VirtualizationManager cmdlet. When you add the VirtualCenter server, you need to specify whether VMM should communicate with the ESX Server hosts in secure mode by using the SecureMode parameter. In secure mode, a certificate and public key are required for each ESX server host. If you want to trust communications and require only credentials for the hosts, set the SecureMode parameter to $FALSE. For more information about managing a VMware Infrastructure, see Managing a VMware Infrastructure in VMM (http://go.microsoft.com/fwlink/?LinkId=128921).

All newly added ESX Server hosts initially have OK (Limited) status in VMM. To fully manage the virtual machines on the hosts, you must provide credentials with appropriate authority by using the Associate-VMHost cmdlet. If you are managing the VMware environment in secure mode, you must also retrieve a security certificate and public key by using the Get-Certificate and Get-SshPublicKey cmdlets, respectively. In secure mode, you should ensure that the user verifies and accepts both the certificate and the public key for each non-embedded ESX Server host, or verifies and accepts the certificate for each embedded ESX Server host prior to changing the state of the host. After obtaining the appropriate credentials, use the Associate-VMHost cmdlet to change the state of the ESX Server host to OK. For information about the restrictions that apply to virtual machines on a host that has OK (Limited) status, see Supported Virtual Machine Actions for ESX Server Hosts (http://go.microsoft.com/fwlink/?LinkId=134489).

The following script adds a VirtualCenter server to VMM in secure mode, gets the ESX Server hosts, prompts the user to accept the certificate and public key, and then changes the state of the ESX Server hosts to OK.
