InfoScale™ Cluster Server 9.0 Bundled Agents Reference Guide - AIX

Device

List of interfaces and their base IP addresses.

When a network interface or a network adapter of the type MultiNICA under VCS control is renamed, you must update the value of the Device attribute of the MultiNICA resource.

For each system you must localize the attribute with a separate base IP address.

Type and dimension: string-association

Example: { en0 = "10.128.8.42", en1 = "10.128.8.42" }

Gateway

IP address for the default gateway.

Type and dimension: string-scalar

Example: "10.192.1.7", "2620:128:f0a2:900c::1"

One of the following attributes:

BroadcastAddr

Broadcast address

Type and dimension: string-scalar

Example: "10.192.15.255"

PrefixLen

Specifies the prefix for the IPv6 address represented as the CIDR value.

When you use the IPv6 protocol, you must configure values for this attribute, the Device, Protocol attributes, and the corresponding IPMultiNIC resources' PrefixLen attributes.

Type-dimension: integer-scalar

Range: 1 - 128

Example: 64

Protocol

Required to use the IPv6 protocol.

See Table: Optional attributes.

HandshakeInterval

To prevent spurious failovers, the agent must try to contact a host on the network several times before it marks an interface as FAULTED. Increased values result in longer failover times, whether between the interface or from system to system in the case of FAULTED interfaces.

Type and dimension: integer-scalar

Default: 1

NetworkHosts

The list of hosts on the network that are pinged to determine if the network connection is alive. Enter the IP address of the host, instead of the host name, to prevent the monitor from timing out. DNS lookup causes the ping to hang. If this attribute is unspecified, the monitor tests the NIC by pinging the broadcast address on the interface. If more than one network host is listed, the monitor returns online if at least one of the hosts is alive.

Type and dimension: string-vector

Example: {"128.93.2.1", "128.97.1.2"}

For a dual-stack or mixed mode configuration:

Example: { "10.209.112.1", "2620:128:f0a2:900c::1" }

Options

The ifconfig command options for the base IP address.

Type and dimension: string-scalar

Example: "metric 4 mtu 1400"

PingOptimize

Determines whether to ping every monitor cycle.

A value of 0 means that the agent pings either the network hosts or the broadcast address every monitor cycle. It pings every cycle to determine the state of the network interface.

A value of 1 means that the agent uses the device statistics from the netstat output to determine the state of the interface. If no activity exists on the interface, the agent then pings the broadcast address to double-check the state of the network interface.

Type and dimension: integer-scalar

Default: 1

RouteOptions

Specifies the routing options that are passed to the route add command when the agent configures an interface. The RouteOptions attribute value is generally formed like this: "destination gateway metric".

For details about the route command, refer to the man page for your operating system.

When the value of this string is null, the agent does not add routes.

Type and dimension: string-scalar

Example: "192.100.201.0 192.100.13.7"

FailoverInProgress

For internal use only.
