Have you run the commands that will create the device tree etc,

Do you have the symcli commands available?

ifparse(1M)						  System Administration Commands					       ifparse(1M)

NAME
ifparse - parse ifconfig command line SYNOPSIS
/sbin/ifparse [-fs] addr_family commands DESCRIPTION
Use the ifparse command to parse the ifconfig(1M) command line options and output substrings, one per line, as appropriate. If no options are specified, ifparse returns the entire ifconfig command line as a series of substrings, one per line. OPTIONS
The ifparse command supports the following options: -f Lists only substrings of the ifconfig command line that are relevant to IP network multipath failover -s Lists only substrings of the ifconfig command line that are not relevant to IP network multipath failover OPERANDS
The ifparse command does not support the interface operand of the ifconfig command. EXAMPLES
Example 1: Parsing Command Line Options Relevant to Failover The following example shows the use of the ifparse command to parse the command line options relevant to IP network multipath failover: example# ifparse -f inet 1.2.3.4 up group one addif 1.2.3.5 -failover up set 1.2.3.4 up Example 2: Parsing Command Line Options That Are Not Relevant to Failover The following example shows the use of the ifparse command to parse the command line options that are not relevant to IP network multipath failover: example# ifparse -s inet 1.2.3.4 up group one addif 1.2.3.5 -failover up group one addif 1.2.3.5 -failover up Example 3: Parsing the Command Line For All Options The following example shows the use of the ifparse command to parse the command line for all ifconfig options: example# ifparse inet 1.2.3.4 up group one addif 1.2.3.5 -failover up group one set 1.2.3.4 up addif 1.2.3.5 -failover up ATTRIBUTES

ifconfig(1M), attributes(5) DIAGNOSTICS
usage: -fs <addr_family> <commands> This message indicates an invalid command line. ifparse: Not enough space This message indicates insufficient memory. ifparse: dhcp not supported for inet6 DHCP operations are not supported for the inet6 address family. ifparse: Operation <operation> not supported for <addr_family> Most operations cannot be used with all address families. For example, the broadcast operation is not supported on the inet6 address fam- ily. ifparse: no argument for <operation> Some operations, for example broadcast, require an argument. NOTES
The ifparse command is classified as an obsolete interface. It will likely be removed in a future release. You should not develop applica- tions that depend upon this interface. SunOS 5.10 9 May 2001 ifparse(1M)
