4.6. Setup Network Param eters
•Install and configure all network interfaces and corresponding network connections.
Refer to IBM's internal network technologies home page for resources on configuring and
tuning networks and TCP/IP.
The network interfaces section of the lsnode report from each node shows the network
interfaces that are configured.
To determine how many network interfaces are available on (AIX):
% lsdev -C -S a -c if
% netstat -i
To determine how many network interfaces are available (Linux):
% netstat -i
To determine if an SP switch is available (AIX):
% lsdev -C -S a -l css0
% netstat -i
To view all IP addresses associated with a local host on AIX (i.e., for all network interf aces):
Note: Does not work for SP switch interface.
% for x in `lsdev -C -S a -c if -F name`; do
lsattr -E -a netaddr -l $x -F value
done
To view additional information for each network interface (AIX):
% for x in `lsdev -C -S a -c if -F name`; do
ifconfig $x
lsattr -El $x
done
For non-AIX platforms, use the Name column from netstat -i in the ifconfig commands.
Note the IP address follows the inet phrase in the output from the ifconfig command.
To test whether an IP address is reachable (non-zero exit status indicates the pi ng was not
successful):
% ping -c 1 <ipAddress>
•Isolate Kerberos communication to the designated control network(s) on all HPSS and DB2
nodes in order to separate the HPSS control and data paths.
•Place all HPSS, DB2, and Kerberos server node IP addresses in a local host table (/etc/ hosts).
For AIX, configure the node to use the table as backup in the event of a DNS failure. The fi le
/etc/netsvc.conf should be modified to look like the following:
hosts=bind,local
The netsvc.conf file is used to specify the ordering of host name resolution. In the above
ordering, DNS will be used first; if the host name is not found, then the local /e tc/host file
