Export LUN IDs with Path Selection Policy

In this post we are sharing a PowerCLI script that we used to export a list of LUNs attached to ESXi hosts in a cluster along with the details of Path Selection Policy selected for the LUN and CommandsToSwitchPath parameter set for the LUNs.

Script was tested on below versions:

  • PowerCLI version 11.5.0 build 14912921
  • vSphere 6.7U3

Script:

Set-PowerCLIConfiguration -InvalidCertificateAction Ignore -Confirm:$false
$cred = Get-Credential
Connect-VIServer vCenter_IP/FQDN -Credential $cred

$getCluster = Get-Cluster -Name "Cluster_Name"
$getESXis = $getCluster | Get-VMHost
$printluns=@()

foreach ($getESXi in $getESXis)
{
    $getLUNsforESXi = Get-VMhost $getESXi | Get-ScsiLun -LunType disk | Select VMHost, CanonicalName, MultipathPolicy, CommandsToSwitchPath
    $printluns = $printluns + $getLUNsforESXi
}

$printluns | Export-Csv C:\users\Administrator\Desktop\PathtoSaveFile.csv -NoTypeInformation 

Disconnect-VIServer -Confirm:$false

Just replace the vCenter_Server_IP_Address/FQDN, Cluster_Name and Path of CSV File and run the script to generate a report of LUNs mapped to all ESXi hosts in a vSphere cluster in your environment. BOOM!!

Happy Scripting!!

Script to Create Multiple Datastores

There was a requirement in one of the projects to create multiple (approx. 60) datastores using a PowerCLI script. We wrote a PowerCLI script to perform this operation on multiple LUNs presented to all ESXi hosts in the cluster.

Requirements:

  • PowerCLI
  • PowerShell 5.1 or later

Script:

Set-PowerCLIConfiguration -InvalidCertificateAction Ignore -Confirm:$false
Connect-VIServer “vCenter_Server_IP_Address/FQDN” -Credential (Get-Credential)

$datanames = Import-Csv ‘C:\Users\Admin\Desktop\File_with_datastore_name_NAA_Ids.csv‘

foreach ($dataname in $datanames)
{
$dataname.Datastore_Name
$dataname.Naa_Id
New-Datastore -VMHost ESXi-01.mycloud.lab -Name $dataname.Datastore_Name -Path $dataname.Naa_Id -Vmfs -FileSystemVersion 6
Get-Cluster -name “Cloud-Clu-01” | Get-VMhost | Get-VMHostStorage –RescanAllHBA
Start-Sleep -Seconds 15
}

Disconnect-VIServer -Confirm:$false

Input File Sample:

Sample of File_with_datastore_name_NAA_Ids.csv

Just replace the vCenter_Server_IP_Address/FQDN, Path of File Containing Datastore Names, NAA Ids, ESXi Host, Cluster Name and Sleep Interval after each Datastore creation operation with the details of your environment. BOOM!!

Happy Scripting!!
