Solution 1520838.1 : How Do I Change The Network Configuration Of The ILOM On An Exalogic Storage Node?

Applies to:

Oracle Exalogic Elastic Cloud X2-2 Hardware - Version All Versions to All Versions [Release All Releases]
Oracle Exalogic Elastic Cloud Software - Version 1.0.0.0.0 and later
Linux x86-64
Oracle Solaris on x86-64 (64-bit)

Goal

Within the Exalogic environment customers might be in the need to change the ILOM IP addresses of the ZFS storage nodes. The process below are the steps to change the IP addresses and network configuration for the ILOM interfaces of either of the two storage nodes included in the Exalogic rack. The documentation links provided also apply to any ILOM interface of any system within the rack.

The goal is to change the network configuration (IP address in this scenario) of the ILOM in the Exalogic ZFS storage node.

NOTE: Prior to doing any changes in the network configurations of any of the ZFS storage nodes inside the Exalogic rack, please consult your system administrator if these changes will affect any other configurations within the network. Also the information provided applies to any system within the Exalogic rack containing ILOM interfaces, which include storage nodes as well as compute nodes.

Solution

There are two ways to change the configuration, via the command line interface (CLI) or the browser user interface (BUI).

Pre-requisites:

Ensure that the new IP address to be used do not create any conflicts with other IP addresses within the network.
Ensure to consult the system administrator for any other issues that could occur by changing the IP addresses.
If the new IP address to be used will be on a separate subnet, losing connection will occur. Please consider connecting to the storage node via the serial management interface to make the change. For more information on this, see our Oracle® Exalogic Elastic Cloud Machine Owner's Guide section "Setting Up Oracle Integrated Lights Out Manager (ILOM), Connecting to ILOM via a Serial Connection" (http://docs.oracle.com/cd/E18476_01/doc.220/e18478/ilom.htm#CHDEAIIC).

Changing the network configuration of the ILOM on a Exalogic ZFS storage Node via CLI:

1. To connect to the CLI via the network, open your SSH client such as PuTTY and connect to the system by using the ILOM hostname or IP address of the ZFS storage node. If you are connecting via a serial connection, please follow the steps described in our Oracle® Exalogic Elastic Cloud Machine Owner's Guide section "Setting Up Oracle Integrated Lights Out Manager (ILOM), Connecting to ILOM via a Serial Connection" (http://docs.oracle.com/cd/E18476_01/doc.220/e18478/ilom.htm#CHDEAIIC).

2. Log in as root:

3. Type the following to verify and view the current configuration "show /SP/network". The output should look something similar to this:

-> show /SP/network

/SP/network
    Targets:
        interconnect
        ipv6
        test

    Properties:
        commitpending = (Cannot show property)
        dhcp_server_ip = none
        ipaddress = 10.141.135.35
        ipdiscovery = static
        ipgateway = 10.141.134.1
        ipnetmask = 255.255.254.0
        macaddress = 00:21:28:AF:B4:A5
        managementport = /SYS/MB/NET0
        outofbandmacaddress = 00:21:28:AF:B4:A4
        pendingipaddress = 10.141.135.35
        pendingipdiscovery = static
        pendingipgateway = 10.141.134.1
        pendingipnetmask = 255.255.254.0
        pendingmanagementport = /SYS/MB/NET0
        sidebandmacaddress = 00:21:28:AF:B4:A5
        state = enabled

    Commands:
        cd
        set
        show

->

4. Next run the following list of commands:

-> set /SP/network pendingipaddress=<IPaddressToChage>
-> set /SP/network pendingipgateway=<GatewayIPtoUse>
-> set /SP/network pendingipnetmask=<NetMaskIPtoUse>
-> set /SP/network commitpending=true

Changing the network configuration of the ILOM on an Exalogic ZFS storage node via BUI:

1. Open a web browser and log into the ILOM browser interface of the ZFS storage node by either entering the ILOM host name or IP address. This IP address should be different than the one used by the ZFS storage appliance configuration console.

ILOM Login screen

2. Navigate to the "Configuration" tab, followed by the "Network" sub tab. Here you will find all the configurations needed to be changed. Note that there are IPv4 and IPv6 configurations. Now change the IP address used for IPv4 in the "IP Address" field. Please change any other field as required. Please use caution when making changes.

3. Finally click "Save" for the changes to take effect.

NOTE: If ILOM network connectivity is lost, the ILOM can be accessed via using the tool "ipmitool".
- login as root:
# ipmitool sunoem cli
...
-> set pendingmanagementport=/SYS/MB/NET0
