Symptoms

When configuring or changing ILOM network interface configuration, one may get the following error:

set: Unable to configure network

Cause

The IP address parameters informed may be invalid or incorrect.

For example, selecting IP addresses from different subnets for the parameters ipaddress and ipgateway will produce such error:

-> set /SP/network pendingipaddress=10.10.13.93
set 'pendingipaddress' to '10.10.13.93'
-> set /SP/network pendingipnetmask=255.255.255.0
set 'pendingipnetmask' to '255.255.255.0'
-> set /SP/network pendingipgateway=10.10.12.7
set 'pendingipgateway' to '10.10.12.7'
-> set /SP/network commitpending=true
set: Unable to configure network

-> show

/SP/network
    Targets:
        interconnect
        ipv6
        test

    Properties:
        commitpending = (Cannot show property)
        dhcp_server_ip = none
        ipaddress = 172.16.2.26
        ipdiscovery = static
        ipgateway = 172.16.2.254
        ipnetmask = 255.255.255.0
        macaddress = 00:21:28:FA:C5:EB
        managementport = /SYS/MB/SP/NETMGMT
        outofbandmacaddress = 00:21:28:FA:C5:EB
        pendingipaddress = 10.10.13.93
        pendingipdiscovery = static
        pendingipgateway = 10.10.12.7
        pendingipnetmask = 255.255.255.0
        pendingmanagementport = /SYS/MB/SP/NETMGMT
        sidebandmacaddress = 00:21:28:FA:C5:EA
        state = enabled

Notice from example above that the netmask used (255.255.255.0) causes ipaddress and ipgateway belong to different subnets, hence the configuration fails.

Solution

In order to have network changes applied, select valid, consistent values for ipaddress and ipgateway within the same subnet address range.

You can find additional information from Oracle documentation:
Oracle Integrated Lights Out Manager (ILOM) 3.0 HTML Documentation Collection
Edit Existing IPv4 Addresses (CLI)
http://docs.oracle.com/cd/E19860-01/E21549/z400157d1038223.html#scrolltoc

Note - If you connected to Oracle ILOM through a remote SSH connection, the connection made to Oracle ILOM using the former IP address will time-out. Use the newly assigned settings to connect to Oracle ILOM.
