Now I will write about how to connect, and where.
Depend on the requirement, you may want to connect to ESXi host or vCenter in order to perform an operation.
Most of the operation can be executed direct after connecting to vCenter, but incase and for a reason vCenter is not available you might connect direct with ESXi Host insted of connecting to vCenter.
Lets assume that we want connect to vCenter and get all the host in all the clusters.
We can use the following commands
#Import Vmware Module Add-PSSnapin VMware.VimAutomation.Core #We Will ask the user to write the username and password for vSphere, you can comment this line if your #vCetner is joined to the domain and you are connected to a domain joined computer $viCredential = Get-Credential -Message "Please Write your vCenter username and password" #This command will be used to connect to Esxi Server or vCenter #You can remote the -Credential $viCredential, if your using domain joined computer and your vCenter is #Joined to the domain Connect-VIServer MyvCenterServer -Credential $viCredential #Get all the Servers in the vCenter in all clustered Get-VMHost | Format-Table -AutoSize name, NumCpu, ConnectionState #Close the remote connection Disconnect-VIServer *
As you can see the main steps are 1- Make sure that you have the module or import then as I explained in part 1
2- Connect-VIServer is used to connect with ESXi host or with the vCenter, in my case I will connect with vCenter
you can remove the -Credential $viCredential if your Esxi hosts and vCenter are joined to the domain and the computer you are using is domain joined computer.
Get-VMHost can be used to get Esxi hosts piping this command to Format-Table it mean that we want to have custom properties in the returned table.
-Autosize will make the columns close to each other.
name, NumCpu, ConnectionState, are properties we want show in the table.
The output will be something like this
Name NumCpu ConnectionState ---- ------ --------------- esxi01.lab.local 32 Connected esxi02.lab.local 32 Connected esxi03.lab.local 32 Connected esxi04.lab.local 32 Connected esxi05.lab.local 32 Connected esxi06.lab.local 32 Connected esxi07.lab.local 32 Connected esxi08.lab.local 32 Connected esxi09.lab.local 32 Connected esxi10.lab.local 32 Connected esxi11.lab.local 32 Connected esxi12.lab.local 32 Connected esxi13.lab.local 32 Connected esxi14.lab.local 32 Connected esxi15.lab.local 32 Connected esxi16.lab.local 32 Connected
Disconnect-viserver * will disconnect all the open session to all VI Servers (ESXi host or vCenter).
If you want to show different properties in the table, you can Pipe Get-VMHost to get-member
so the command will be like Get-VMHost | get-member
Just Run the command above after you connect to vCetner, the result will be like the following
| Name | MemberType |
| ---- | ---------- |
| ConvertToVersion | Method |
| Equals | Method |
| GetHashCode | Method |
| GetType | Method |
| IsConvertableTo | Method |
| LockUpdates | Method |
| ToString | Method |
| UnlockUpdates | Method |
| ApiVersion | Property |
| Build | Property |
| Client | Property |
| ConnectionState | Property |
| CpuTotalMhz | Property |
| CpuUsageMhz | Property |
| CustomFields | Property |
| DatastoreIdList | Property |
| DiagnosticPartition | Property |
| ExtensionData | Property |
| FirewallDefaultPolicy | Property |
| HyperthreadingActive | Property |
| Id | Property |
| IsStandalone | Property |
| LicenseKey | Property |
| Manufacturer | Property |
| MaxEVCMode | Property |
| MemoryTotalGB | Property |
| MemoryTotalMB | Property |
| MemoryUsageGB | Property |
| MemoryUsageMB | Property |
| Model | Property |
| Name | Property |
| NetworkInfo | Property |
| NumCpu | Property |
| Parent | Property |
| ParentId | Property |
| PowerState | Property |
| ProcessorType | Property |
| State | Property |
| StorageInfo | Property |
| TimeZone | Property |
| Uid | Property |
| Version | Property |
| VMSwapfileDatastore | Property |
| VMSwapfileDatastoreId | Property |
| VMSwapfilePolicy | Property |
You can add any Property value to the pipe, lets assume u wana get a list of VMHost in a table and view only PowerState,Name,ProcessorType
#Import Vmware Module Add-PSSnapin VMware.VimAutomation.Core #We Will ask the user to write the username and password for vSphere, you can comment this line if your #vCetner is joined to the domain and you are connected to a domain joined computer $viCredential = Get-Credential -Message "Please Write your vCenter username and password" #This command will be used to connect to Esxi Server or vCenter #You can remote the -Credential $viCredential, if your using domain joined computer and your vCenter is #Joined to the domain Connect-VIServer MyvCenterServer -Credential $viCredential #Get all the Servers in the vCenter in all clustered Get-VMHost | Format-Table -AutoSize PowerState, Name, ProcessorType #Close the remote connection Disconnect-VIServer *

You actually make it seem really easy with your presentation but
I to find this matter to be really one thing which I think I might by no means understand.
It sort of feels too complicated and extremely wide for me.
I am taking a look forward on your subsequent publish, I will attempt to get the cling of it!
