HP StorageWorks 9100 Extreme Data Storage System administration guide V1.0.2 (AN540-96018, February 2010)

Manually configuring network interfaces
Instead of using the exdsmgr reconfigure system command to configure a network interface,
you can manually configure the network interfaces. This can be used to create a bonded network
interface.
To manually configure a network interface, use then following procedure:
1. Use the exdsmgr reconfigure system command and set the IP address to None.
2. Manually configure the appropriate files (/etc/modprobe.conf and /etc/sysconfig/
network-scripts) on all servers.
3. Reboot all servers so that the Matrix software can detect and then monitor the new network inter-
faces.
NOTE:
If you use bonding, do not configure a "bond0" device. This is reserved for future use.
Changing other settings
Use the exdsmgr reconfigure system command to change any of the following system and
network parameters:
• Parameters such as the following:
• DNS domain name—All servers are set to the same domain name.
• DNS servers—Up to three DNS servers are possible.
• NTP Servers—Up to thee NTP servers are possible.
• Mail smart host—A mail relay server.
• Onboard Administrator password
• iLO passwords (same password used for all servers)
• Virtual connect password
• Default e-mail address for alerts
• Matrix password
• The reboot after reconfiguration option
NOTE:
If you change any of the parameters directly (that is, without using the reconfigure system
command), the next time you run the reconfigure system command, your settings could get
overwritten by the HP ExDS9100 system software.
Managing the HP ExDS9100 firewall
Firewall concepts
The HP ExDS system uses iptables to implement a firewall on each server. The iptables rules allow the
servers to communicate with each other and to provide appropriate NAS services to other systems.
