### Windows iSCSI Service Configuration and Troubleshooting

#### Configuring the iSCSI Initiator on Windows Server

To configure an iSCSI initiator within a Windows environment, one must first ensure that the necessary services are enabled. The process involves setting up both client-side (initiator) configurations as well as server-side settings to establish successful connections between storage devices over TCP/IP networks[^1].

For configuring the iSCSI initiator:

- Open 'iSCSI Initiator' from Administrative Tools.
- In the Connection tab, enter the IP address or DNS name of the target portal where the iSCSI targets reside.
- After connecting successfully, go through additional tabs like Discovery, Targets, Volumes and Devices for further setup.

This allows administrators to connect their servers with remote disks provided by other machines acting as iSCSI targets.

#### Common Issues During Setup and Solutions

When encountering issues during the initial connection phase, several common problems may arise such as incorrect login credentials, firewall blocking ports required for communication, or mismatched CHAP secrets when mutual authentication is used. Ensuring proper network connectivity can resolve many potential errors encountered while establishing sessions.

If there's trouble discovering new targets after adding them into discovery data sources, refreshing discovered lists might help refresh available options presented under "Targets". Additionally, checking whether multipathing support has been correctly configured could prevent single points of failure leading to intermittent access failures.

In cases involving performance concerns related specifically to read/write operations performed against attached LUNs via software-based initiators running directly inside guest operating systems rather than hardware offload cards dedicated solely towards this purpose; tuning parameters associated with queue depths per device instance would yield improvements without necessitating physical upgrades immediately.

Set-Disk -Number 2 -IsOffline $false
Initialize-Disk -Number 2 –PartitionStyle MBR
New-Partition -DiskNumber 2 -UseMaximumSize | Format-Volume -FileSystem NTFS -Confirm:$false

The above PowerShell commands demonstrate how to bring online, initialize disk partitions, create volumes, format filesystems accordingly once newly connected SAN drives become visible post-login sequence completion.
