PowerCLI - iSCSI Configuration

iSCSI storage configuration

Create vdSwitch for iSCSI traffic. Switch will have 2 uplinks, and MTU 9000 (Jumbo frames)

$Datacentre = Get-Datacenter -Name Datacentre_01
New-VDSwitch -Name vdSwitch_iSCSI -Location $Datacentre -NumUplinkPorts 2 -MaxPorts 256 -Version "6.0.0" -Mtu 9000 | Out-Null

The iSCSI vdSwitch will have 2 iSCSI port groups associated with vlan 230. vdPG_iSCSI_1 will only use dvUplink1 and vdPG_iSCSI_2 will only use dvUplink2.

Get-VDSwitch -Name vdSwitch_iSCSI | Get-VDPortgroup | Get-VDUplinkTeamingPolicy | Set-VDUplinkTeamingPolicy -ActiveUplinkPort dvUplink1 -UnusedUplinkPort dvUplink2
Get-VDSwitch -Name vdSwitch_iSCSI | New-VDPortgroup -Name vdPG_iSCSI1 -NumPorts 120 -VLanId 230 -PortBinding Ephemeral
Get-VDSwitch -Name vdSwitch_iSCSI | New-VDPortgroup -Name vdPG_iSCSI2 -NumPorts 120 -VLanId 230 -PortBinding Ephemeral
Get-VDSwitch -Name vdSwitch_iSCSI | Get-VDPortgroup -Name vdPG_iSCSI2 | Get-VDPortgroupOverridePolicy | Set-VDPortgroupOverridePolicy -UplinkTeamingOverrideAllowed $true
Get-VDSwitch -Name vdSwitch_iSCSI | Get-VDPortgroup -Name vdPG_iSCSI2 | Get-VDUplinkTeamingPolicy | Set-VDUplinkTeamingPolicy -ActiveUplinkPort dvUplink2 -UnusedUplinkPort dvUplink1

Add esx host to iSCSI switch

Get-VDSwitch -Name vdSwitch_iSCSI | Add-VDSwitchVMHost -VMHost esx-01.localdomain.local
$nic2 = Get-VMHost -Name esx-01.localdomain.local | Get-VMHostNetworkAdapter -Physical -Name vmnic2
$nic3 = Get-VMHost -Name esx-01.localdomain.local | Get-VMHostNetworkAdapter -Physical -Name vmnic3
Get-VDSwitch -Name $vdSwitch_iSCSI_Name | Add-VDSwitchPhysicalNetworkAdapter -VMHostPhysicalNic $nic2 -Confirm:$false
Get-VDSwitch -Name $vdSwitch_iSCSI_Name | Add-VDSwitchPhysicalNetworkAdapter -VMHostPhysicalNic $nic3 -Confirm:$false

Add to iSCSI vdSwitch 2 vmkernel ports for iSCSI traffic (this has to be done for each esx host)

New-VMHostNetworkAdapter -VMHost esx-01.localdomain.local -VirtualSwitch vdSwitch_iSCSI  -PortGroup vdPG_iSCSI1 -IP 192.168.101.1 -SubnetMask 255.255.255.0 -Mtu 9000
New-VMHostNetworkAdapter -VMHost esx-01.localdomain.local -VirtualSwitch vdSwitch_iSCSI  -PortGroup vdPG_iSCSI2 -IP 192.168.101.101 -SubnetMask 255.255.255.0 -Mtu 9000

Enable software iSCSI storage adapter on esx host

Get-VMHostStorage -VMHost $HostName | Set-VMHostStorage -SoftwareIScsiEnabled $true

Add iSCSI vmkernel ports to iSCSI vdSwitch

$iSCSI1_nic = Get-VMHostNetworkAdapter -VMHost esx-01.localdomain.local | where {$_.IP -like "192.168.101.1"} | select Name
$iSCSI2_nic = Get-VMHostNetworkAdapter -VMHost esx-01.localdomain.local | where {$_.IP -like "192.168.101.101"} | select Name
$HBANumber = Get-VMHostHba -VMHost esx-01.localdomain.local -Type iSCSI | %{$_.Device}
$esxcli = Get-EsxCli -VMHost esx-01.localdomain.local 
$esxcli.iscsi.networkportal.add($HBANumber,$true,$iSCSI1_nic.Name)
$esxcli.iscsi.networkportal.add($HBANumber,$true,$iSCSI2_nic.Name)

Add iSCSI target and rescan for storage

$HBANumber = Get-VMHostHba -VMHost esx-01.localdomain.local -Type iSCSI | %{$_.Device}
New-IScsiHbaTarget -IScsiHba $HBANumber -Address "192.168.101.201"
Get-VMHostStorage -VMHost esx-01.localdomain.local -RescanAllHba
Get-VMHostStorage -VMHost esx-01.localdomain.local -RescanVmfs

Additionally you may want to change iSCSI software adapter Advances Settings. Typically you will disable "DelayedAck" and i.e. for Equallogic array increase "LoginTimeout". I couldn't find any direct command to do this so I have to use Get-View. More about storage manipulation you can find here.

$HostView = Get-VMHost esx-01.localdomain.local | Get-View
$HostStorageSystemID = $HostView.configmanager.StorageSystem
$HBANumber = ($HostView.config.storagedevice.HostBusAdapter | where {$_.Model -match "iSCSI Software"}).device

$options = New-Object VMWare.Vim.HostInternetScsiHbaParamValue[] (2)
$options[0] = New-Object VMware.Vim.HostInternetScsiHbaParamValue  
$options[0].key = "DelayedAck"  
$options[0].value = $false 
$options[1] = New-Object VMware.Vim.HostInternetScsiHbaParamValue  
$options[1].key = "LoginTimeout"  
$options[1].value = 60 

$HostStorageSystem = Get-View -ID $HostStorageSystemID  
$HostStorageSystem.UpdateInternetScsiAdvancedOptions($HBANumber , $null, $options)

And finally I have put all commands together to make easy script to configure iSCSI on a cluster

PowerCLI - Cluster Configuration

I've just decided to create some step by step guide how to create VMware cluster via PowerCLI
Please keep in mind that this guide will not show you how to configure all parameters but should give you an idea how to start.

Prerequisite for this guide:

• vCentre server has to be installed and static IP configured
• All ESX hosts should have hypervisor installed and static management IP configured
• There has to be network connectivity between vCentre and ESX hosts

Connect to your vCentre server

 
Connect-VIServer vcentre.localdomain.local

Get default folder list, we will use it to create datacentre
