Managing Serviceguard Eighteenth Edition, September 2010

IP Address
This node’s host IP address(es), to be used on
this interface. If the interface is a standby and
does not have an IP address, enter 'Standby.'
An IPv4 address is a string of 4 digits separated
with decimals, in this form:
nnn.nnn.nnn.nnn
An IPV6 address is a string of 8 hexadecimal
values separated with colons, in this form:
xxx:xxx:xxx:xxx:xxx:xxx:xxx:xxx.
For more details of IPv6 address format, see the
Appendix G (page 475).
NETWORK_FAILURE_DETECTION
When there is a primary and a standby network
card, Serviceguard needs to determine when a
card has failed, so it knows whether to fail traffic
over to the other card. The configuration file
specifies one of two ways to decide when the
network interface card has failed:
• INOUT
• INONLY_OR_INOUT
The default is INOUT.
See “Monitoring LAN Interfaces and Detecting
Failure: Link Level” (page 92) for more
information.
NETWORK_AUTO_FAILBACK
See the NETWORK_AUTO_FAILBACK parameter
description under“Cluster Configuration
Parameters ” (page 143).
Kind of LAN Traffic
Identify the purpose of the subnet. Valid types
include the following:
• Heartbeat
• Client Traffic
• Standby
This information is used in creating the subnet groupings and identifying the IP
addresses used in the cluster and package configuration files.
Setting SCSI Addresses for the Largest Expected Cluster Size
SCSI standards define priority according to SCSI address. To prevent controller
starvation on the SPU, the SCSI interface cards must be configured at the highest
