Create Multi-path I/O for iSCSI Targets (optional)
For a Microsoft-based target solution, multiple paths to the target device are created by providing multiple iSCSI initiator identifiers for the same target. In the example above, we add a second and third IP address that is to be associated with the same iSCSI initiator, so that there are three IP addresses that can access the target. These three addresses are associated with three Ethernet ports on the same host server.
Configure Security for iSCSI Targets (optional)
If security is desired for the iSCSI communication between the initiator and the target, the CHAP secret can be entered in the Authentication tab.
Make iSCSI Targets Ready for Use for iSCSI Initiators
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 for each of the two iSCSI targets. These 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 “P” 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 1.34 TB 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 three more virtual disks. After configuring the virtual disks, the management console shows the virtual disks associated with each iSCSI target.
The target side configuration is now complete.
