Configuring the SLES9 network

Before installing SF Oracle RAC on SLES9, some network configuration is required on SLES9.

 To configure a SLES9 network for SF Oracle RAC

1. If it is not already set to yes, set HOTPLUG_PCI_QUEUE_NIC_EVENTS in /etc/sysconfig/hotplug to "yes":

   HOTPLUG_PCI_QUEUE_NIC_EVENTS=yes

2. Make sure that all ethernet devices are brought online at boot time by including them as MANDATORY_DEVICES. This ensures that LLT interfaces are available before configuration.

   For example:

   # grep MANDATORY_DEVICES /etc/sysconfig/network/config MANDATORY_DEVICES="eth-id-00:04:23:a5:99:bc eth-id-00:04:23:a5:99:bd eth-id-00:30:6e:4a:62:50 eth-id-00:30:6e:4a:63:5d"

   Each entry in the MANDATORY_DEVICES list is of the form eth-id-<macaddress>.

   Make the appropriate entries in this list using the mac addresses of the interfaces present.

3. To ensure that the interface name to MAC address mapping remains the same across reboots, Veritas requires that PERSISTENT_NAME entries be added to the configuration files for all the network interfaces, including those that are not currently used:
   • Run:

     ifconfig -a.

   • For each ethernet interface displayed:
     • If it does not already exist, create a file named:

       /etc/sysconfig/network/ifcfg-eth-id-<mac>

       where <mac> is the hardware address of that interface. Make sure that <mac> contains lower case characters.

       If a file named ifcfg-eth0 exists then delete it.

     • Add the following line at the end of this file:-

       PERSISTENT_NAME=<ethX>

       where ethX is the interface name for this interface.

     • Example:

       Enter: ifconfig -a

       eth0 Link encap:Ethernet HWaddr 00:02:B3:DB:38:FE

       inet addr:10.212.99.30 Bcast:10.212.99.25
       Mask:255.255.254.0

       inet6 addr: fe80::202:b3ff:fedb:38fe/64 Scope:Link

       UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1

       RX packets:453500 errors:0 dropped:0 overruns:0 frame:0

       TX packets:8131 errors:0 dropped:0 overruns:0
       carrier:0

       collisions:0 txqueuelen:1000

       RX bytes:35401016 (33.7 Mb) TX bytes:999899 (976.4
       Kb)

       Base address:0xdce0 Memory:fcf20000-fcf40000

       If it does not already exist, create a file named:

       /etc/sysconfig/network/ifcfg-eth-id-00:02:b3:db:38:fe

       Add to the end of this file the following line:

       PERSISTENT_NAME=eth0

   • Repeat this procedure for all interfaces displayed by ifconfig -a.
