POWERCLI VMWARE: CONFIGURE SOFTWARE ISCSI STORAGE ADAPTER AND ADD VMFS DATASTORE

This blog article is similar to my previous notes VMWARE ESXI INSTALL AND CONFIGURE SOFTWARE ISCSI STORAGE ADAPTER FOR VMFS VERSION 6 DATASTORE. Here I am using VMware Powercli instead of vSphere web client to configure iScsi storage adpater and add new datastore. As this is complete powercli article I will not use GUI at all.

I am configuring my first Esxi server. Storing its information in variable called $VMhost.
$VMhost = Get-VMhost Esxi001.vcloud-lab.com

Next install and enable iSCSI software adapter.
$VMhost | Get-VMHostStorage | Set-VMHostStorage -SoftwareIScsiEnabled $True

vmware vsphere esxi powercli add enable iscsi storage adapter vmhba, host bus adapter, get-vmhost, get-vmhoststorage, Set-vmhoststorage, SoftwareIScsiEnabled

Before processing further first I will do ping and telnet test on esxi server to storage and vice versa, As this is complete powercli article, for this I will enable SSH service on Esxi server using below command.
$VMHost | Get-VMHostService | ? {$_.Key -eq 'TSM-SSH'} | Start-VMHostService -Confirm:$false

Remotely vmware vsphere esxi Get-VMHostservice TSM-SSH, Where-Object enable SSH powercli Start-VMhostService -confirm

Putty to esxi server. The telnet command is not available in any versions of ESXi and, therefore, you must use netcat (nc) to confirm connectivity to a TCP port on a remote host. The syntax of the nc command is: nc -z <destination-ip> <destination-port>, I am telneting port 3260 and succeeded means good (This is also a guide how to telnet in vmware esxi)

nc -z 172.20.1.101 3260
Connection to 172.20.1.101 3260 port [tcp/*] succeeded!

To use telnet command on Microsoft Windows telnet client needs to be installed with PowerShell command Install-WindowsFeature Telnet-Client. run telnet IP port, prompt is changed means I can go ahead with further configuration.

Install-windowsFeature telnet-client, esxi telnet 3260 iscsi, nc, netcat putty esxi ssh

After enabling iScsi software adapter I need iSCSI IQN name, which I will need to add on storage server in initiator list.
$VMhost | Get-VMHostHba -Type iScsi | Select-Object Name, Status, IScsiName

vmware powercli Get-VMHostHba -type iscsi and select-object iscsiname vmhba online

Below command is ran on Microsoft iSCSI target, in the Initiator list, without this Esxi will not able to view or access LUN. Refer this article POWERSHELL INSTALLING AND CONFIGURING MICROSOFT ISCSI TARGET SERVER
Set-IscsiServerTarget -TargetName Boot-Esxi001 -InitiatorIds iqn:iqn.1998-01.com.vmware:esxi001-5abe60a5

Microsoft iSCSI Target server set-iscsiServertarget -targetName -InitiatorId for hyperv vmware esxi

Add storage target IP in the software iScsi storage adapter static discovery. (Get-VMHostHba -Type iscsi parameter shows software adapter)
$VMhost | Get-VMHostHba -Type iScsi | New-IScsiHbaTarget -Address 172.20.1.101

Next is needed devicename of iSCSI VMkernel adapter configured earlier. Ref. article POWERCLI: VMWARE ESXI CONFIGURE (VSWITCH) VMKERNEL NETWORK PORT FOR ISCSI STORAGE, with using Where-Object filtering on Get-VMHostNetworkAdapter -VMkernel I easily get the needed DeviceName. I got two results vmk1 and vmk2. note them down.
$VMhost | Get-VMHostNetworkAdapter -VMKernel | ? {$_.PortGroupName -match 'iSCSI'} | select Devicename

add target ip and information vmware vsphere powercli configure vcenter esxi get-vmhosthba -type iscsi, new-IscsiHbaTarget -address, get-VMHostNetworkAdapter -vmkernel portgroupname, deviceName vmk1.png

After getting information about VMkernel port name, I need device name of vmhba using:
$VMHost | Get-VMHostHba -Type IScsi | Select Device

Next step use EsxCli and add vmkernel ports to network port binding,
$esxcli = $VMhost | Get-EsxCli
$esxcli.iscsi.networkportal.add('vmhba65',$Null,'vmk1')
$esxcli.iscsi.networkportal.add('vmhba65',$Null,'vmk2')

Once everything is successful rescan for HBA and VMFS on esxi server.
$VMhost | Get-VMHostStorage -RescanAllHba -RescanVmfs

vmware powercli configure iscsi rescan stroage device, refresh get-vmhosthba -type iscsi, device, $esxcli vmhost, get-esxcli, $esxcli.iscsi.networkportal.add,  rescanall, rescanvmfshba

If above steps are successful, It requires NAA id of Free LUN for last step, to find free lun follow this article FIND FREE OR UNASSIGNED STORAGE LUN DISKS ON VMWARE ESXI SERVER.
Get-FreeEsxiLUNs -Esxihost Esxi001.vcloud-lab.com

vmware vsphere powercli connect-viserver get-freeEsxiLUNs, shows or find free esxi lun remote storage disk

Once NAA id is rectified use New-Datastore command to format LUN with VMFS type, I am using complete space here.
$VMhost | New-Datastore -Name Disk1_Tier3 -Path naa.60003ff44dc75adc9601165db783a4ac -Vmfs

vmware vsphere esxi vmhost, new-datastore tier -path naa find, capacitygb and freespaceGB

If you add another Esxi host adding datastore is not required, This formatted datastore will be automatically be visible once configuring VMKernel ports and iSCSI software adapter. New-Datastore need to run once only for newly presented storage disk.
