Configure Security for iSCSI Targets (optional)
CHAP can be configured with a password also known as the “CHAP secret”. The CHAP secret provides an additional level of security between the iSCSI initiator and target. The CHAP secret is provided on the “Authentication” tab of the target properties.

Virtual disks need to be created on the iSCSI targets for Microsoft-based iSCSI target solutions. These virtual disks represent the storage volumes that the iSCSI initiators will use. The maximum capacity represented by all the virtual disks on a given iSCSI target on a Microsoft-based iSCSI target solution is two terabytes (2 TB) per target. In this example, we create a 100 GB and 200 GB virtual disk on the iSCSI target. These two virtual disks will be viewed as volumes by the iSCSI initiators over the TCP/IP network.
By right-clicking on the target name, the “Create Virtual Disk” wizard is launched.
The virtual disk is created on the internal disk volume that is available to the iSCSI target. In this case, it is the “N” volume.
The size of the virtual disk depends on the needs of the application on the host server. For this virtual disk, we choose a size of 100 GB from the available 501 GB on this volume.
A description, although optional, is useful for better management.
This virtual disk must be associated with an iSCSI target in order for the application host to use this storage as an iSCSI storage volume.
This completes the virtual disk configuration.
We repeat this process to create a second virtual disk of size 200 GB. After configuring the virtual disks, the management console shows the virtual disks associated with the iSCSI target.
The iSCSI target device view shows the total volume size and the free space remaining on the device that is available for iSCSI targets.
The target side configuration is now complete.
