The Get-InitiatorPort cmdlet is a part of Windows PowerShell, specifically used in the context of managing iSCSI (Internet Small Computer Systems Interface) configurations. This cmdlet is utilized to retrieve information about the iSCSI initiator ports on a Windows system. iSCSI is a protocol that allows clients to send SCSI commands to storage devices on remote servers, making it a crucial component in storage area networks (SANs).

Examples:

Example 1: Retrieving All iSCSI Initiator Ports

To get a list of all iSCSI initiator ports on your system, you can use the following PowerShell command:

Get-InitiatorPort

This command will output details about each initiator port, including its NodeAddress, PortAddress, and other relevant information.

Example 2: Filtering Specific Initiator Ports

If you want to filter and display only specific initiator ports, you can use the Where-Object cmdlet. For instance, to find ports with a specific NodeAddress:

Get-InitiatorPort | Where-Object { $_.NodeAddress -eq "iqn.1991-05.com.microsoft:example-initiator" }

Replace "iqn.1991-05.com.microsoft:example-initiator" with the actual NodeAddress you are interested in.

Example 3: Exporting Initiator Port Information

You might want to export the initiator port information to a CSV file for reporting or auditing purposes. Here's how you can do it:

Get-InitiatorPort | Export-Csv -Path "C:\Path\To\Your\Folder\InitiatorPorts.csv" -NoTypeInformation

This command will save the information to a CSV file at the specified path.

Understanding the Output

The output of Get-InitiatorPort includes several important properties:

• NodeAddress: The iSCSI Qualified Name (IQN) of the initiator.
• PortAddress: The address of the port.
• PortType: The type of the port, which can be software or hardware.
• ConnectionType: Indicates whether the connection is over TCP/IP or some other protocol.

Prerequisites

Before using the Get-InitiatorPort cmdlet, ensure that the iSCSI Initiator Service is running on your Windows machine. You can start the service using the following command if it is not already running:

Start-Service -Name MSiSCSI

Conclusion

The Get-InitiatorPort cmdlet is a powerful tool for managing and auditing iSCSI configurations in a Windows environment. By using the examples provided, you can effectively retrieve and manage iSCSI initiator port information, aiding in the maintenance and optimization of your storage network.
