How It Works
The physical SAS disks in both the storage servers and compute servers are managed with an LSI MegaRAID
SAS controller and can be managed and queried using the 64-bit MegaCLI RAID management tool,
/opt/MegaRAID/MegaCli/MegaCli64
.
MegaCLI is used by various support tools, such as
sundiag.sh
, and also used or requested when troubleshooting,
patching, or working with Oracle Support. MegaCLI also provides a valuable mechanism to understand your Exadata
storage devices; understanding the various command-line options to MegaCli64 is often important for an Oracle
Exadata DMA.
7-12. Administering the Storage Cell Network Using ipconf
Problem
You wish to view your storage cells network configuration and optionally use
ipconf
to modify your storage server or
compute server's network configuration.
Solution
Oracle's
ipconf
utility is used on Exadata servers to configure server network interfaces. It is invoked during system
startup and is invoked from the
/opt/oracle.cellos/cellFirstboot.sh
script.
ipconf
will set network information based on information in your
cell.conf
file. The default
cell.conf
file is
located in
/opt/oracle.cellos/cell.conf
:
[root@cm01cel01 ~]# more /opt/oracle.cellos/cell.conf
$VAR1 = {
'Internal' => {
'Interface infiniband prefix' => 'ib',
'Interface ethernet prefix' => 'eth'
},
'Hostname' => 'cm01cel01.centroid.com',
'Timezone' => 'America/Detroit',
'Ntp drift' => '/var/lib/ntp/drift',
'Interfaces' => [
{
'Hostname' => 'cm01cel01-priv.centroid.com',
'IP address' => '192.168.10.3',
'Net type' => 'Private',
'Netmask' => '255.255.252.0',
'Slaves' => [
'ib0',
'ib1'
],
'State' => 1,
'Name' => 'bondib0'
},
