Operations
This chapter describes the control of the LAN for operation management of the ETERNUS DX Disk storage
system, and the monitoring the status of the ETERNUS DX Disk storage system.
4.1

LAN for Operation Management

The ETERNUS DX Disk storage system must be connected to the LAN for operation management. When remote
support is used, information on errors of the ETERNUS DX Disk storage system or other events can be notified
to the remote support center.
• Make sure to connect each controller to the LAN for operation management.
• The LAN ports of the ETERNUS DX Disk storage system support IPv4 and IPv6.
Note that an IPv6 network is used for an ETERNUS DX Disk storage system with firmware version V10L30
or later.
This section explains how the LAN control controller of the ETERNUS DX Disk storage system operates.
■ LAN control controller (Master CM/Slave CM)
For a dual-controller type, the controller (CM) that is given the authority to manage the LAN is called the
Master CM and the other CM is called the Slave CM.
When an error occurs in the Master CM or LAN, the Master CM is switched automatically.
IP addresses of the LAN ports are not assigned to each controller. These IP addresses are assigned to the role
of master or slave. If the Master CM is switched, the same IP addresses are reused. Therefore, even if the
Master CM is switched and the physical port is changed, access can be maintained via the same IP addresses.
