Managing the Network Configuring Storage Module Communication Use the Communication tab to configure the network interface used by the storage module to communicate with other storage modules on the network and to update the list of managers that the storage module can communicate with. Figure 72. Selecting the Storage System Software Network Interface and Updating the List of Managers Selecting the Interface Used by the Storage System Software The Storage System Software uses one network interface for communication with other storage modules on the network. In order for clustering to work correctly, the Storage System Software communication interface must be designated on each storage module. The interface can be • a single NIC that is not part of a bond • a bonded interface consisting of 2 or 4 bonded NICs Note: Only NICs that are in the Active or Passive (Ready) state can be designated as the communication interface. You cannot make a disabled NIC the communication interface. When you initially set up a storage module using the Configuration Interface, the first interface that you configure becomes the interface used for Storage System Software communication. Warning: To change the communication interface, first remove the storage module from the management group. To select a different communication interface: 1. Select TCP/IP Network from the configuration categories. 118 Intel® Storage System Software User Manual

Intel® Storage System Software User Manual

Configuring Storage Module Communication

Use the Communication tab to configure the network interface used by the storage module

to communicate with other storage modules on the network and to update the list of

managers that the storage module can communicate with.

Figure 72. Selecting the Storage System Software Network Interface and

Updating the List of Managers

Selecting the Interface Used by the Storage System Software

The Storage System Software uses one network interface for communication with other

storage modules on the network. In order for clustering to work correctly, the Storage

System Software communication interface must be designated on each storage module.

The interface can be

•

a single NIC that is not part of a bond

•

a bonded interface consisting of 2 or 4 bonded NICs

Note:

Only NICs that are in the Active or Passive (Ready) state can be designated as the

communication interface. You cannot make a disabled NIC the communication interface.

When you initially set up a storage module using the Configuration Interface, the first

interface that you configure becomes the interface used for Storage System Software

communication.

Warning:

To change the communication interface, first remove the storage module from the

management group.

To select a different communication interface:

Select TCP/IP Network from the configuration categories.
