Overview - Sun Microsystems StorEdge 3900 Series Reference And Service Manual

16.1

Overview

The Storage Service Processor of the Sun StorEdge 3900 and 6900 Series storage
system contains Storage Automated Diagnostic Environment software that identifies
devices, logs events, and alerts Sun engineers by email and pager if the data falls
outside of pre-defined tolerances.
The Storage Service Processor communicates on two networks. The internal
component LAN (IP address 192.168.0.0) and the SP LAN (IP address 10.0.0.0). The
SP Lan is used to aggregate multiple Storage Service Processors and the NTC.
There may be cases where the LAN addresses have been changed to accommodate
special circumstances. In these cases, you need to determine some preliminary
information about the Storage Service Processor and the network it resides on before
the new NTC can be set up. The information needed is the following:
IP address of the Storage Service Processor
Netmask of the network
Broadcast of the network
IP address that will be used to setup the NTC
Most of this information can be obtained by running the ifconfig(1M) command
on the Storage Service Processor. The interface information that is not the lo0 FRU
is the information required.
The following example output from ifconfig shows the Storage Service Processor
IP address (10.0.0.10), the netmask being used (255.0.0.0), and the broadcast being
used (109.0.0.255).
# /usr/sbin/ifconfig -a
lo0: flags=1000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4> mtu 8232 index 1
