Part 1: How to configure iSCSI in Clustered Data ONTAP 8.2

All the below is done at the cluster prompt (which is nac1::> in this lab).

The following commands:
- Add required licenses
- Create a Vserver and allow for iscsi only
- Modify/setup Vserver login accounts
- Create a Vserver Management LIF
- Create 2 x iSCSI Data LIFs
- Create an iSCSI server
- Create a LUN Portset
- Create a volume

Now we should have everything in place for SnapDrive to do its magic and create the iSCSI sessions, LUNs, igroups, and LUN maps!

NetApp Clustered ONTAP 8.2, iSCSI, and MPIO with Server 2012: Part 2/5

In this 5 part series, we:
Part 1: Configure iSCSI on Clustered Data ONTAP
Part 2: Set up Windows Server 2012 with iSCSI and MPIO, NetApp Host Utilities, NetApp DSM for MPIO
Part 3: How to install NetApp SnapDrive for Windows 7.0
Part 4: Use NetApp SnapDrive for Windows to create a disk and attach via iSCSI
Part 5: Use the NetApp Data ONTAP DSM to manage paths and modify MPIO path policies

Part 2: Set up Windows Server 2012 with iSCSI and MPIO, NetApp Host Utilities, and NetApp DSM for MPIO

Note: Windows Server 2012 Standard Edition, Clustered Data ONTAP 8.2, NetApp iSCSI Host Utilities 6.0.2, NetApp DSM 4.0.1, and NetApp SnapDrive for Windows 7.0, is a support combination at http://support.netapp.com/matrix

2.1) How to setup Windows Server 2012 for iSCSI and MPIO

We have a vanilla install of Windows 2012 Standard Edition Server patched up to October 2013. In this lab the server is not domain joined. A local administrative user called snapdrive has been created, and this account is used for installing softwares and - later on - as the snapdrive service account.

Login as snapdrive (for all Windows tasks in this series):

Image: SnapDrive Local Login Used in this Lab

Open up PowerShell run as administrator:
To Disable UAC via Powershell:

New-ItemProperty -Path HKLM:Software\Microsoft\Windows\CurrentVersion\policies\system -Name EnableLUA -PropertyType DWord -Value 0 -Force

shutdown -r -t 0

Open up PowerShell:
To turn the Windows firewall off:

netsh advfirewall set allprofiles state off

To configure with two NICs (using Ethernet 3 and 4 here) with IP address on the iSCSI subnet, and disable IPv6:

New-NetIPAddress -IPAddress 10.10.10.11 -InterfaceAlias "Ethernet 3" -AddressFamily IPv4 -PrefixLength 24
New-NetIPAddress -IPAddress 10.10.10.12 -InterfaceAlias "Ethernet 4" -AddressFamily IPv4 -PrefixLength 24
Disable-NetAdapterBinding -InterfaceAlias “Ethernet 3” -ComponentID ms_tcpip6
Disable-NetAdapterBinding -InterfaceAlias “Ethernet 4” -ComponentID ms_tcpip6

Enable iSCSI and install the MPIO feature:

Set-Service -Name msiscsi -StartupType Automatic
Start-Service msiscsi
Enable-WindowsOptionalFeature –Online –FeatureName MultiPathIO

Note: Disabling UAC and turning off the Windows Firewall is not a requirement, just done here out of preference as it makes life easier!

2.2) Obtaining Softwares


NetApp Windows Host Utilities 6.0.2 (netapp_windows_host_utilities_6.0.2_x64)
NetApp Data ONTAP DSM for Windows MPIO 4.0.1 (ntap_win_mpio_4.0.1_setup_x64)
NetApp SnapDrive for Windows 7.0 (SnapDrive7.0_x64)

There is a recommended patch for the NetApp Windows Host Utilities 6.0.2 for Windows Server 2012, download from http://support.microsoft.com/kb/2796995:
457359_intl_x64_zip

Image: Softwares Downloaded in Preparation

2.3) How to Install NetApp Windows Host Utilities 6.0.2 using CLI

*All the install softwares have been installed in C:\Software

Install the recommended patch for Windows Server 2012:

Open up PowerShell:

PS C:\Users\admin> cd C:\software
PS C:\software> .\457359_intl_x64_zip.exe
PS C:\software> .\Windows8-RT-KB2796995-x64.msu
PS C:\software>

And restart!

Install NetApp Windows Host Utilities 6.0.2:

Open up PowerShell:

PS C:\Users\admin> cd c:\Software
PS C:\Software> msiexec /i netapp_windows_host_utilities_6.0.2_x64.msi /quiet MULTIPATHING=1

And the server reboots automatically!

2.4) How to Install NetApp Data ONTAP DSM for Windows MPIO 4.0.1 using the CLI

Open up PowerShell:

PS C:\Users\admin> cd c:\Software
PS C:\Software> cmd
C:\Software> start /b /wait msiexec /package ntap_win_mpio_4.0.1_setup_x64.msi /quiet LICENSECODE=your_key_here HYPERVUTIL=0 USESYSTEMACCOUNT=1

And the server reboots automatically!

Image: It does take 2/3 minutes to install - very likely it will sit on Enabling feature(s) at 66.6% for 2 minutes or more!

+ Lots of polish!

An opinion on vSphere Application HA:
Edited quote from Gostev@Veeam - “First, this feature is not something built into the platform, but rather completely "glued" on top of it. Before you can even start using this feature, you will need to deploy two separate appliances. The first appliance is Hyperic appliance which is Microsoft SCOM like tool with ugly web interface (carrying maybe 10% of SCOM functionality), and sporting identical architecture (thus bringing 100% of SCOM complexity along). Second appliance is actual VMware AppHA appliance, which orchestrates "stuff" between Hyperic server and vCenter Server. AppHA requires that you deploy special monitoring agents in every VM!”
