The MDCU performs:
• Storage array configuration
• Host configuration
Storage Array Configuration
Before a host iSCSI initiator and an iSCSI-based storage array can
communicate, they must be configured with information such as which IP
addresses and authentication method to use. Since iSCSI initiators establish
connections with an already configured storage array, the first task is to
configure your storage arrays to make them available for iSCSI initiators.
This utility requires network access to the management ports of the storage arrays
you wish to configure. You must have a properly functioning network
infrastructure before attempting to configure your storage arrays. If your storage
arrays are already configured, you can skip directly to the host configuration.
This configuration task generally involves the following steps:
1
Discover available storage array(s) for configuration.
2
Select a storage array to configure.
3
Set a storage array name and password.
4
Configure the IP protocols and addresses for the management ports.
5
Configure the IP protocols and addresses for the iSCSI ports.
6
Specify the CHAP authentication method.
7
Apply the settings after reviewing a summary.
8
Repeat the process starting from step 2 to configure additional arrays.
Host Configuration (Host Connectivity Configuration)
After you have completed configuring your iSCSI-based storage arrays, the
next task is to run this utility on all hosts that need to access the storage
arrays. Depending on your network configuration, your host 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 on which the utility
is running does not have an iSCSI initiator or the required driver components
installed. When the option is disabled, the utility also displays an
