Phenomenon
The device cannot communicate or a timeout occurs.
Action
Check that the device power supply is on, and that there are no problems on the LAN.
Refer to "9.1.2 Changing the operating environment" before modifying the IP address.
For communication devices that use the SNMP protocol, such as Fibre Channel switches and storage devices, the community names of the target device and administrative server may not match. To modify the community name of the target device, refer to "C.2 sanma.conf Parameter", to set the community name, and then reflect the settings in the settings file.
In server nodes, check that the Agent is running.
To modify the host name after the server node device has been registered, follow the procedures in "9.1.2.4 Changing the name of a server node (host)".
Check that there are no problems with the communication mode settings in the network environment. If one communication mode is set to "Auto Negotiation" while the other is set to "Full Duplex" communications may be slow, this needs to be corrected.
