System management

A clustered system is managed by using a command-line session or the management GUI over an Ethernet connection.

Each system node has two Ethernet ports that can be used for management. Ethernet port 1 must be configured with a management IP address and must be connected on all nodes in the system. The use of Ethernet port 2 is optional.

Warning: On Lenovo Storage V3700 V2 and Lenovo Storage V3700 V2 XP systems, Ethernet port 2 is used as the technician port during the system initialization. If you manually enabled the technician port, do not use port 2 for host or management I/O as data traffic is redirected. However, if port 2 is used for host I/O, it is highly recommended that you set up service IP addresses on the first management port (port 1).

At any time, only one node in the system can operate as the focal point for configuration and monitoring requests. This node is called the configuration node. It is the only node that activates the management IP addresses. You can use one or more of these addresses to access the system through the management GUI or the command-line interface (CLI).

Each system node has one or two management IP addresses.

You can access the management GUI through a service IP address or the technician port on the configuration node.

Note: Management IP addresses that are assigned to a system are different from iSCSI IP addresses and are used for different purposes. If iSCSI is used, iSCSI addresses are assigned to node ports. On the configuration node, a port has multiple IP addresses active at the same time.

In addition to these IP addresses, you must add one service IP address per node to provide access to the service assistant.
