System management

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

Each Lenovo Storage V7000node 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.

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 Lenovo Storage V7000 system can have zero to four management IP addresses. You can assign up to two Internet Protocol Version 4 (IPv4) addresses and up to two Internet Protocol Version 6 (IPv6) addresses.

Each Lenovo Storage V7000 node has one or two management IP addresses.

Depending on the configuration, each Lenovo Storage V7000 node has one or two management IP addresses and up to six Internet Small Computer System Interface over Internet Protocol (iSCSI IP) addresses per node.

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 can optionally add one service IP address per node to provide access to the service assistant.
