Integrated Management Module (IMM) static IP address and Dynamic Domain Name System (DDNS) issue - IBM System x

Troubleshooting


Problem

The Integrated Management Module (IMM) Dynamic Domain Name System (DDNS) feature may not work when the network interface is configured to use static Internet Protocol (IP) configuration. IBM has tested the feature and found that there is an issue with the configuration. This RETAIN tip demonstrates how to set up IMM and name the server.

Workaround

Complete the following steps to configure the IMM and name the server:

Note: The following Domain Name System (DNS) server and IMM firmware are used in these examples:

  • DDNS server: Ubuntu 10.04 LTS, Bind9 1.9.7.0, IP: 10.0.0.2

    OR

  • DNS server: Windows 2003 or 2008 DNS Server

    AND

  • IMM: YUOO91E or above, IP: 10.0.0.100

1. Configure the IMM with the following settings:

Under the IMM Web Interface page "Network Interface":

  IPv6: Disabled
Hostname: immtest01
Domain Name: mydomain.org
DDNS Status: Enabled
Domain Name Used: Manual
Dynamic Host Configuration Protocol (DHCP): Disabled - Use static IP configuration
Static IP Address: 10.0.0.100
Save settings.

Under the IMM Web Interface page "Network Protocols":

  DNS: Enabled
DNS Server: 10.0.0.2
Preferred DNS Servers: IPv4
Save all settings and restart the IMM.

2A. If using a Linux DNS server:

Add the following zone configuration file to the bind9 configuration and change the IP address and domain name to a name of your choice:

  /etc/bind/named.conf.local
zone "mydomain.org" IN <open_curly_brace>
type master;
file "/var/lib/bind/mydomain.org.db";
allow-update <open_curly_brace>any;<close_curly_brace>;
notify yes;
<close_curly_brace>;

zone "0.0.10.in-addr.arpa"<open_curly_brace>
type master;
file "/var/lib/bind/rev.0.0.10.in-addr.arpa";
<close_curly_brace>;

/var/lib/bind/mydomain.org.db
$ORIGIN .
$TTL 259200 ; 3 days
mydomain.org IN SOA dns1.mydomain.org. root.mydomain.org.
(
2007091366 ; serial
28800 ; refresh (8 hours)
14400 ; retry (4 hours)
2419200 ; expire (4 weeks)
86400 ; minimum (1 day)
)
NS dns1.mydomain.org.
$ORIGIN mydomain.org.
dns1 A 10.0.0.2

/var/lib/bind/rev.0.0.10.in-addr.arpa
$TTL 86400;
@ IN SOA dns1.mydomain.org. root.mydomain.org.(
2007091340;
28800;
14400;
2419200;
86400;
);
IN NS dns1.mydomain.org.
40 IN PTR dns1.mydomain.org.

2B. If using a Linux DNS server:

Manually remove the A record of the IMM's Full Qualified Domain Name (FQDN) in the zone configuration and restart the bind9 service.

  1. Ping or nslookup to make sure the FQDN cannot be resolved.
  2. Restart the IMM.
  3. Wait until the IMM Web Graphical User Interface (GUI) starts.
  4. Ping or nslookup the IMM's FQDN.

These steps create a working DDNS test environment for the IMM.

The bind9 configuration files are following:

3. If using a Windows DNS Server:

On the Windows DNS server management console:

  1. Right-click on the forward look-up domain and go to "Properties"
  2. On the "General" tab for the drop-down box "Dynamic Updates" you must change the setting to "Nonsecure and secure" (The IMM does not have the ability to send secure DNS updates.)
  3. Save these settings for the Windows DNS server. You may need to reload the forward look-up domain.

4. On the IMM log you should see the following message:

  "DDNS registration successful. The domain name is <yourdomain.com>"

If you do not see this message, please reboot your IMM so that the Service Processor can register with the DDNS server properly.

Additional information

The cause of the issue is the wrong configuration of the DNS server or IMM.

DDNS support was added to IMM firmware at level 91E.
