5.3 Configuring the Network Environment

Express uses SNMP to register disk storage systems. Therefore, before registering devices, it is required to start SNMP Agent. Those disk storage systems that have not SNMP Agent started cannot be registered.

Check the network environment, access privileges and settings of communication mode between management server and disk storage system. If either communication mode of the management server or the disk storage system is set to "Full (full duplex)", do not set the other to "Auto Negotiation".

Refer to the manual for each disk storage system and check the network environment settings.

If the network environment configurations are insufficient, set up them with the ETERNUS Web GUI or FibreCAT SX WBI (web-browser interface).

If a firewall is placed, set the following port numbers to the firewall.

Table 5.2 Setting up a firewall between the management server and the ETERNUS Disk storage system
Port Number	Protocol	Communication Start Direction
23	tcp	Communication from management server to ETERNUS Disk storage system.
161	udp	Communication from management server to ETERNUS Disk storage system.
162	udp	Communication from ETERNUS Disk storage system to management server.
1999	tcp	Communication from management server to ETERNUS Disk storage system.

Note

The telnet connection and the Maintenance connection should be available in setting up interface on the ETERNUS Disk storage system.

Table 5.3 Setting up a firewall between the management server and the FibreCAT SX Disk storage system
Port Number	Protocol	Communication Start Direction
161	udp	From management server to FibreCAT SX Disk storage systems.
162	udp	From FibreCAT SX Disk storage systems to management server.

Table 5.4 Setting up a firewall between the management server and the PC using Express (or server)
Port Number	Protocol	Communication Start Direction
9855	tcp	Communication from PC or server using Express to management server.

Note

Notes in combination with products using the SNMP trap reception function

As with ServerView AlarmService, Express use OS standard SNMP trap reception service for fault management with SNMP Trap reception.

Therefore, if any of the following products is mixed, take the same setting procedure as ServerView AlarmService is mixed.
