may be the same machine you use to manage your storage arrays, or it may be on a completely separate
network.
The option to configure a host is disabled if the machine the utility is running on does not have an iSCSI
initiator or the required driver components installed. When the option is disabled, the utility also displays
an informational message. If you are running the utility on a host which is not connected to the iSCSI
based storage array (or which you do not wish to connect to the array), the informational message can
be ignored.
The task involves the following steps:
1.
Discover available storage array(s) for connection.
2.
Select a storage array.
3.
Specify the CHAP secret.
4.
Select the iSCSI ports the host's initiator uses to log on.
5.
Repeat the process starting from step 2 to connect to additional arrays.
6.
Repeat these steps on each host that needs access to the storage array(s).
Before Starting The Configuration Process
Before you start configuring the storage array or host connectivity, it is recommended that you fill out the
iSCSI configuration worksheet to help you plan your configuration. You may need to use several
worksheets depending on your configuration.
Keep the following guidelines in mind for the storage array and host configuration:
• For optimal performance, ensure your network configuration is valid. See the storage array's Support
Matrix at
dell.com/powervaultmanuals
.
• If your host has multiple network interfaces, it is recommended that each network interface uses a
separate subnet.
• For redundancy in a dual controller (duplex) configuration, ensure each host network interface is
configured to connect to both storage array controllers.
• For optimal load balancing, ensure each host network interface that is used for iSCSI traffic is
configured to connect to each storage array controller.
• It is recommended that each host network interface only establishes one iSCSI session per storage
array controller.
NOTE: The utility tries to follow the guidelines for the host connectivity whenever possible based on
the available host network interfaces and their connectivity with the iSCSI host ports of the storage
array.
Configure The Storage Array Using PowerVault MDCU
To configure the iSCSI-based storage array(s) using PowerVault MDCU:
1.
Launch the utility (if it is not launched automatically) from the server with access to the management
ports of the storage array(s) to be configured.
• For Windows, click
Start
→
All Programs
→
Dell
→
MD Storage Software
→
Modular Disk
Configuration Utility.
• For Linux, click the
MDCU
icon on the desktop or navigate to the /opt/dell/mdstoragesoftware/
mdconfigurationutility directory in a terminal window and run
PowerVault MDCU
.
The MDCU automatically discovers all the available storage arrays.
2.
In the
Discover MD Arrays
window, select the iSCSI storage array you want to configure.
