  1. The network won't be available yet because we reinitialized the network adapters so the following changes will need to be done in the VM. Log in as root/racattack. Type the command system-config-network. Device configuration is already highlighted. Press Enter.
    2. RA-Oracle_Linux_6_64bit-Configure_OS-post clone network change
  2. eth0 (eth0) - Ethernet is already highlighted. Press Enter.
    3. RA-Oracle_Linux_6_64bit-Configure_OS-post clone network save devices
  3. Go down to the Static IP line. Change the IP to 192.168.78.52. Go down to Ok and press Enter.
    4. RA-Oracle_Linux_6_64bit-Configure_OS-post clone network eth0
  4. Select eth1 (eth1) - Ethernet and press Enter. Go down to the Static IP line. Change the IP to 172.16.100.52. Go down to Ok and press Enter.
    5. RA-Oracle_Linux_6_64bit-Configure_OS-post clone network eth1
  5. Tab down to Save and press Enter.
    6. RA-Oracle_Linux_6_64bit-Configure_OS-post clone network save devices
  6. Arrow down to DNS configuration and press Enter.
    7. RA-Oracle_Linux_6_64bit-Configure_OS-post clone DNS configuration
  7. In the Hostname field, change to collabn2.racattack. Tab down to Ok and press Enter.
    8. RA-Oracle_Linux_6_64bit-Configure_OS-post clone network dns change
  8. Tab down to Save&Quit and press Enter.
    9. RA-Oracle_Linux_6_64bit-Configure_OS-post clone network save quit
  9. Check that the parameter PEERDNS is set to no in /etc/sysconfig/network-scripts/ifcfg-eth2 to prevent the resolv.conf from being overwritten by the dhcp client:
    10. DEVICE=eth2 TYPE=Ethernet UUID=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxx ONBOOT=yes NM_CONTROLLED=yes BOOTPROTO=dhcp HWADDR=xx:xx:xx:xx:xx DEFROUTE=yes PEERDNS=no PEERROUTES=yes IPV4_FAILURE_FATAL=yes IPV6INIT=no NAME="System eth2" USERCTL=no
  10. Remove the udev network rules file. It will be regenerated on the next reboot with the new MAC addresses.
    11. [root@collabn2 ~]# rm -f /etc/udev/rules.d/70-persistent-net.rules
  11. Remove the HWADDR and UUID lines in the network adapter configuration files.
    12. [root@collabn2 ~]# sed -i -e '/HWADDR/d' -e '/UUID/d' /etc/sysconfig/network-scripts/ifcfg-eth[0-2]
  12. Reboot the collabn2 VM by typing reboot.
    13. Start the collabn1 VM as well and start Putty sessions for both. RA-Oracle_Linux_6_64bit-Configure_OS-collabn1 reboot
  13. Verify that all the network interfaces are up.
    14. [root@collabn2 ~]# ip l 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000 link/ether 08:00:27:c9:39:d3 brd ff:ff:ff:ff:ff:ff 3: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000 link/ether 08:00:27:33:bd:a8 brd ff:ff:ff:ff:ff:ff 4: eth2: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000 link/ether 08:00:27:5f:61:29 brd ff:ff:ff:ff:ff:ff
  14. Verify that all the ASM devices are visible.
    15. [root@collabn2 ~]# ls -l /dev/asm* brw-rw----. 1 oracle dba 8, 17 Aug 5 15:40 /dev/asm-disk1 brw-rw----. 1 oracle dba 8, 33 Aug 5 15:40 /dev/asm-disk2 brw-rw----. 1 oracle dba 8, 49 Aug 5 15:40 /dev/asm-disk3 brw-rw----. 1 oracle dba 8, 65 Aug 5 15:40 /dev/asm-disk4
