How To Find WWN on Windows 2012 R2
Are you trying to locate the WWN (World Wide Name) on Windows Server 2012 R2? The WWN is crucial for managing your HBA (Host Bus Adapters) and facilitating communication between storage devices and your server.
Fortunately, PowerShell offers straightforward methods to obtain this information swiftly. Here are two efficient approaches to fetch the WWN on your Windows Server 2012 R2.
Method 1: Using Get-WmiObject
- Open PowerShell: Launch PowerShell with administrative privileges.
- Run the Command: Enter the following command to retrieve the WWN on your HBA Adapters:
Get-WmiObject -class MSFC_FCAdapterHBAAttributes -namespace "root\WMI" | ForEach-Object {(($_.NodeWWN) | ForEach-Object {"{0:x}" -f $_}) -join ":"}
This command uses the Get-WmiObject cmdlet to query the MSFC_FCAdapterHBAAttributes class in the root\WMI namespace. It then formats the obtained WWN information for easy reference.
Method 2: Using Get-InitiatorPort
You can get the same results by issuing a simpler command:
Get-InitiatorPort
This straightforward command retrieves the necessary WWN information without the need for additional complexity.
Which Method Should You Use?
Whether you opt for the detailed command in Method 1 or the quick query in Method 2, these PowerShell commands will provide you with the essential WWN details for your HBA Adapters on Windows Server 2012 R2.
Understanding and having access to the WWN is crucial for various administrative tasks, especially when configuring storage devices and managing server connectivity. These PowerShell commands streamline the process, allowing you to retrieve the necessary information promptly and efficiently.
Frequently Asked Questions
What is a WWN (World Wide Name)?
A WWN (World Wide Name) is a unique identifier assigned to each port on a Fibre Channel HBA (Host Bus Adapter). It is used to identify and route traffic between storage devices and servers in a SAN (Storage Area Network) environment.
Does the Get-InitiatorPort command work on all Windows Server versions?
The Get-InitiatorPort cmdlet is available on Windows Server 2012 and later versions. For older versions of Windows Server, you may need to use the Get-WmiObject method or third-party tools.
Can I find the WWN without PowerShell?
Yes, you can also find the WWN through Device Manager by expanding Storage Controllers, right-clicking the HBA adapter, and checking its properties. However, PowerShell is the fastest and most reliable method.
What is the difference between WWNN and WWPN?
WWNN (World Wide Node Name) identifies the HBA node itself, while WWPN (World Wide Port Name) identifies individual ports on the HBA. Storage admins typically use the WWPN for zoning and LUN masking configurations.
