How to Backup or Recover SPBM with PowerCLI

We have discussed about the SPBM  and how to create SPBM on previous posts , today we are going to discuss about how can backup and restore the SPBM from Power CLI  .

Why we need backup or restore operation on SPBM 

Just imagine once the case we have to redeploy our vCenter which is coiffured with vSAN  and there are many policy . In such cases power CLI is the best tool to perform backup and restore of SPBM .

You can use below commands to perform required tasks

Check the Available Policy 

# Get-SpbmStoragePolicy

I  have created and using two policies on my vSAN environment New Test Policy and New ISCSI Test Policy

# Get-SpbmStoragePolicy -Name "Policy Name"

Check the Policy Detail with specific name which we provide

# Get-SpbmStoragePolicy  | Format-List

Get the Options available with Get-SpbmStoragePolicy Command

#Get-SpbmStoragePolicy -Id "PolicyId"

Listing policy with policy ID which we found from above command

#Get-SpbmStoragePolicy -Requirement -Namespace "VSAN"

Returns all storage policies of type Requirement containing one or more rules which contain one or more capabilities from the "VSAN" namespace

Export the Policy 

# Export-SpbmStoragePolicy -StoragePolicy $policy -FilePath 'folder\file path'

Exported File Looks like below

Exports a storage policy to the policy.xml file in location . If a file with the same name already exists in this location, the file is overwritten. And if you do not use the Force parameter, the command returns an error about the existing file.

Import Policy 

#Import-SpbmStoragePolicy -Name "Policy Name" -Description "PolicyDescription" -FilePath C:\policy.xml

Imports a storage policy with your name " Policy Name" and description "PolicyDescription" from the policy.xml file to a server. 
And new storage policy is created on the server.

Export All Policy

If you want to export all the policy to specific folder  , you can follow below power shell script .

# Get a list of all the storage policies on the specified vCenter Server
$StoragePolicies = Get-SpbmStoragePolicy

# Enumerate the list of storage policies
Foreach($StoragePolicy in $StoragePolicies) {

# Get the name of the policy that is being exported.
$PolicyName = $StoragePolicy.Name

Export-SpbmStoragePolicy -FilePath C:\Users\Administrator\Desktop\POLICY\ -StoragePolicy $StoragePolicy.Name
}

Note :- This Script will work only for after connecting to vCenter from power CLI else you have add commands to connecting to vCenter to this script .

Collect vSwicth Information Using vSphere Power CLI

In this  Post  sharing the Script to collect the Virtual Standard Switch Information from vSPhere power cli to CSV file .

You can Modify  the Location of the file to save and directly apply to vSPhere Cli Window or  you can save this as .PS1  extension and run  CLI window .

Script 

&{foreach($esx in Get-VMHost){
$vNicTab = @{}
$esx.ExtensionData.Config.Network.Vnic | %{
$vNicTab.Add($_.Portgroup,$_)
}
foreach($vsw in (Get-VirtualSwitch -VMHost $esx)){
foreach($pg in (Get-VirtualPortGroup -VirtualSwitch $vsw)){
Select -InputObject $pg -Property @{N="ESX";E={$esx.name}},
@{N="vSwitch";E={$vsw.Name}},
@{N="Active NIC";E={[string]::Join(',',$vsw.ExtensionData.Spec.Policy.NicTeaming.NicOrder.ActiveNic)}},
@{N="Standby NIC";E={[string]::Join(',',$vsw.ExtensionData.Spec.Policy.NicTeaming.NicOrder.StandbyNic)}},
@{N="Portgroup";E={$pg.Name}},
@{N="VLAN";E={$pg.VLanId}},
@{N="Device";E={if($vNicTab.ContainsKey($pg.Name)){$vNicTab[$pg.Name].Device}}},
@{N="IP";E={if($vNicTab.ContainsKey($pg.Name)){$vNicTab[$pg.Name].Spec.Ip.IpAddress}}}
}
}
}} | Export-Csv C:\vswitch.csv -NoTypeInformation -UseCulture

Result 

Result of the script will shown like below .

Find Number of VCPU used in a Cluster and ESXi hosts

This Post explain how can we generate an output contains , Total number of vCpu used in an vCenter Cluster , also it shows many vCPU used per Esxi hosts .  If you have  multiple Cluster it is very easy to find same using below script.

Connect-VIServer  "vCenter Name"

$TotalNumvCPUs = 0
Foreach ($Cluster in (Get-Cluster |Sort Name)){
$HostNumvCPUs = 0
Write-Host “Cluster: $($Cluster.name)“
Foreach ($ESXHost in ($Cluster |Get-VMHost |Sort Name)){
Write-Host “ Host: $($ESXHost.name)“
$RunningLimit = $null
$RunningLimit = ($ESXHost |Get-VMHostAdvancedConfiguration).get_Item(“Misc.RunningVCpuLimit“)
If ($RunningLimit -eq $null){
$RunningLimit = 128
}
Write-Host “ Misc.RunningVCpuLimit: $RunningLimit“
Foreach ($VM in ($ESXHost |Get-VM)){
$HostNumvCPUs += ($VM).NumCpu
}
Write-Host “ Number of vCPU on host: $($HostNumvCPUs)“
$TotalNumvCPUs += $HostNumvCPUs
$HostNumvCPUs = 0
}
Write-Host “———-“
Write-Host “Number of vCPU in $($Cluster.name): $TotalNumvCPUs“
Write-Host “———-“
Write-Host “”
$TotalNumvCPUs = 0
}

NTP Conflagration with Power CLI

Check NTP Services status 

Get-VMHost | Get-VmHostService | Where-Object {$_.key -eq "ntpd"}

Check Firewall exception configuration 

Get-VMHost | Get-VMHostFirewallException | where {$_.Name -eq "NTP client"}

Enable the FirewallException to all ESXi Hosts

Get-VMHost | Get-VMHostFirewallException | where {$_.Name -eq "NTP client"} |Set-VMHostFirewallException -Enabled:$true

Disable the FirewallException to all ESXi Hosts

Get-VMHost | Get-VMHostFirewallException | where {$_.Name -eq "NTP client"} |Set-VMHostFirewallException -Enabled:$false

Start the NTP service on all ESXi nodes

Get-VMHost | Get-VmHostService | Where-Object {$_.key -eq "ntpd"} | Start-VMHostService

Stop the NTP service on all ESXi nodes

Get-VMHost | Get-VmHostService | Where-Object {$_.key -eq "ntpd"} | Stop-VMHostService   ( use  " -Confirm:$false to avaoid the the popoup quetion abut confimration )

Add the NTP servers to all ESXI Hosts

Get-VMHost | Add-VMHostNtpServer 192.168.1.1o,192.168.1.11

Verify NTP servers added  by running below command

Get-vmhost esx1.test.com |Get-VMHostNtpServer

Remove the NTP servers from ESXi Hots 

Get-vmhost esx1.test.com |Remove-VMHostNtpServer 192.168.1.10,192,168,1,11  -confirm:$false

Check the NTP Policy Configured 

Get-VMhost | Get-VmHostService | Where-Object {$_.key -eq "ntpd"}

Configure the  NTP Policy 

Get-VMhost | Get-VmHostService | Where-Object {$_.key -eq "ntpd"} | Set-VMHostService -policy "automatic"

Note:- Get-VMhost "ESXIHOSTNAME" , if you use this you can apply these setting only to that HOST

             It is recommended to set the time manually prior to starting the service.

CBT Management with Power CLI

List all virtual machines where CBT enabled 

Get-VM| Where-Object{$_.ExtensionData.Config.ChangeTrackingEnabled -eq $true}

Check specific virtual machines where CBT enabled 

Get-VM  "TEST-VM-01" | Where-Object{$_.ExtensionData.Config.ChangeTrackingEnabled -eq $true}

List all virtuals machine where CBT disabled

Get-VM| Where-Object{$_.ExtensionData.Config.ChangeTrackingEnabled -eq $false}

Check specific virtual machines where CBT disabled

Get-VM  "TEST-VM-01" | Where-Object{$_.ExtensionData.Config.ChangeTrackingEnabled -eq $false}

Note : In GUI mode we cannot modify the CBT configuration while virtual machine is powered on , so we can use below script to enable or disable CBT in VM powered on state.

Script to enable CBT

$vmtest = Get-VM TEST-VM-01 | get-view
$vmConfigSpec = New-Object VMware.Vim.VirtualMachineConfigSpec
$vmConfigSpec.changeTrackingEnabled = $true
$vmtest.reconfigVM($vmConfigSpec)

Script to disable CBT

$vmtest = Get-VM TEST-VM-01 | get-view
$vmConfigSpec = New-Object VMware.Vim.VirtualMachineConfigSpec
$vmConfigSpec.changeTrackingEnabled = $disabale
$vmtest.reconfigVM($vmConfigSpec)

You may use the above commands by pasting on vSphere CLI after connecting to vCenter   or  save it as .PS1  extension and run from the directory
