Required Attributes

Required Attribute Description, Type and Dimension, Default, and Example

Address

Virtual IP address assigned to the active NIC.

MultiNICResName

Name of associated MultiNICA resource that determines the active NIC.

Optional Attributes

Optional Attribute Description, Type and Dimension, Default, and Example

IfconfigTwice

Causes an IP address to be configured twice using an ifconfig up-down-up sequence. Increases the probability of gratuitous ARP requests (generated by ifconfig up) to reach clients.

NetMask

The netmask associated with the IP address of the resource. Specify the value of the netmask in decimal (base 10) or hexadecimal (base 16).


Note    VERITAS recommends that you specify a netmask for each virtual interface.

Options

Options for the ifconfig command.

  • Type and dimension: string-scalar
  • Example: "broadcast 192.203.15.255"

Note   Note    VERITAS recommends that you set the RestartLimit for IPMultiNIC resources to a greater-than-zero value. This helps to prevent the spurious faulting of IPMultiNIC resources during local failovers of MultiNICA. A local failover is an interface-to- interface failover of MultiNICA. See the VCS User's Guide for more information.

Sample Configuration: IPMultiNIC and MultiNICA

For details on the following example, refer to Sample Configuration: MultiNICA and IPMultiNIC.
