Changing Storage Cell Ethernet Networking
Now complete the following steps:

First, log in as root on each storage cell and stop your Cell Services software: 1.

[root@cm01cel01 ~]# service celld stop
Stopping the RS, CELLSRV, adn MS services...
The SHUTDOWN of services was sucessful.
[root@cm01cel01 ~]#

Next, copy your active cell.conf file to a temporary directory to prepare for editing: 2.

[root@cm01cel01 ~]# locate cell.conf
/opt/oracle.cellos/cell.conf
/opt/oracle.cellos/iso/lastGoodConfig/cell.conf
/root/ExadataRescued/lastGoodConfig/cell.conf
[root@cm01cel01 ~]# cp /opt/oracle.cellos/cell.conf /tmp/new.cell.conf
[root@cm01cel01 ~]#

Now you will need to change network address in your /tmp/new.cell.conf file. In the
Interfaces stanza, find the Ethernet network section; you will find these by searching for
the storage cell hostname. An example of this section follows:

3.

{
'Hostname' => 'cm01cel01.centroid.com',
'IP address' => '172.16.1.12',
'Netmask' => '255.255.255.0',
'Net type' => 'Management',
'Name' => 'eth0',
'State' => 1,
'Gateway' => '172.16.1.1'
},

Change the network settings to your new IP address. Next, find the ilom stanza in your
/tmp/new.cell.conf file and make the necessary changes:

4.

'ilom' => {
'ILOM Nameserver' => '11.11.1.250',
'ILOM Timezone' => 'America/Detroit',
'ILOM Netmask' => '255.255.255.0',
'ILOM IP address' => '10.16.1.17',
'ILOM Search' => 'centroid.com',
'ILOM Second NTP server' => '0.0.0.0',
'ILOM Short Hostname' => 'cm01cel01-ilom',
'ILOM Fully qualified hostname' => 'cm01cel01-ilom.centroid.com',
'ILOM First NTP server' => 'pool.ntp.org',
'ILOM Gateway' => '10.16.1.1',
'ILOM Use NTP Servers' => 'enabled'
}
