PowerCLI - Datastore manipulation


Get all LUNs connected to host

Get-Cluster -Name ClusterName | Get-VMHost -Name HostName | Get-ScsiLun

Get all "disk" LUNs connected to host

Get-Cluster -Name ClusterName | Get-VMHost -Name HostName | Get-ScsiLun -LunType disk

Get alldatastores name, free space, capacity

Get-View -ViewType Datastore -Property Name, Info | Get-VIObjectByVIView

Set MultiPath Policy to "RoundRobin" on all LUNs which have not "RoundRobin" already

Get-Cluster -Name ClusterName | Get-VMHost -Name HostName | Get-ScsiLun -LunType disk | Where {$_.MultiPathPolicy -ne "RoundRobin"} | Set-ScsiLun -MultiPathPolicy "RoundRobin"

Get full information of all LUNs connected to host (you can find here SAN device Model which will be used in next command)

Get-Cluster -Name ClusterName | Get-VMHost -Name HostName | Get-ScsiLun | fl

Set MultiPath Policy to "RoundRobin" on all LUNs where SAN model is "VRAID"

Get-Cluster -Name ClusterName | Get-VMHost -Name HostName | Get-ScsiLun -LunType disk | Where {$_.MultiPathPolicy -ne "RoundRobin" -and $_.Model -eq "VRAID"} | Set-ScsiLun -MultiPathPolicy "RoundRobin"

Get Canonical Name ans Capacity of all LUNs attached to each host in the cluster

foreach ($v in $(get-cluster -Name ClusterName | Get-VMHost)) {$v.name; Get-VMHost -name $v.Name | Get-ScsiLun | select CanonicalName,CapacityGB}

Get Canonical Name and Prefered Path of all LUNs connected to host where Path Policy is set to "Fixed" and SAN model is not "VRAID"

Get-Cluster -Name ClusterName | Get-VMHost -Name HostName | Get-ScsiLun -LunType disk | Where {$_.MultiPathPolicy -eq "Fixed" -and $_.Model -ne "VRAID"} | Get-ScsiLunPath | select ScsiCanonicalName, Name | Export-Csv -NoTypeInformation -UseCulture -Path c:\test\zone1_path.csv

Get all Equallogic datastore path policy and iop to switch path

Get-VMHost | Get-ScsiLun | Where {$_.Vendor -eq "EQLOGIC"} | select VMHost, MultipathPolicy, CommandsToSwitchPath

Get all Equallogic datastore path policy to "RoundRobin" and iop to switch path to "3"

Get-VMHost | Get-ScsiLun | Where {$_.Vendor -eq "EQLOGIC"} | Set-ScsiLun -MultipathPolicy RoundRobin -CommandsToSwitchPath 3

Display all datastores attached to ESX hosts with their Canonical Names

get-vmhost -Name HostName | Get-Datastore | Where-Object {$_.ExtensionData.Info.GetType().Name -eq "VmfsDatastoreInfo"} | ForEach-Object { if ($_) {$Datastore = $_; $Datastore.ExtensionData.Info.Vmfs.Extent | Select-Object -Property @{Name="Name";Expression={$Datastore.Name}},DiskName}}
