Moving All Drives from One Storage Server to Another

You might need to move all drives from one storage server to another storage server. This situation might occur when a chassis-level component fails, such as a motherboard or Oracle ILOM, or when you are troubleshooting a hardware problem.

To move the drives between storage servers:

1. Back up the files in the following directories:

   • /etc/hosts

   • /etc/modprobe.conf

   • /etc/sysconfig/network

   • /etc/sysconfig/network-scripts

2. Inactivate all grid disks and shut down the storage server. See "Shutting Down a Storage Server".
3. Ensure that the Oracle ASM disk_repair_time attribute is set long enough, so that Oracle ASM does not drop the disks before you can activate the grid disks in another storage server.
4. Move the physical disks, flash disks, disk controller, and USB flash drive from the original storage server to the new storage server.

   Caution:

   • Ensure that the first two disks, which are the system disks, are in the same, first two slots. Otherwise, the storage server will function improperly.

   • Ensure that the flash cards are installed in the same PCIe slots as in the original storage server.

5. Power on the new storage server. You can either use the service processor interface or press the power button.
6. Log in to the console using the service processor.
7. Check the files in the following directories. Restore corrupt files from the backups.

   • /etc/hosts

   • /etc/modprobe.conf

   • /etc/sysconfig/network

   • /etc/sysconfig/network-scripts

8. Use the ifconfig command to retrieve the new MAC addresses for eth0, eth1, eth2, and eth3. This example shows that the eth0 MAC address (HWaddr) is 00:14:4F:CA:D9:AE.

   # ifconfig eth0
   eth0      Link encap:Ethernet  HWaddr 00:14:4F:CA:D9:AE
             inet addr:10.204.74.184  Bcast:10.204.75.255  Mask:255.255.252.0
             inet6 addr: fe80::214:4fff:feca:d9ae/64 Scope:Link
             UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
             RX packets:141455 errors:0 dropped:0 overruns:0 frame:0
             TX packets:6340 errors:0 dropped:0 overruns:0 carrier:0
             collisions:0 txqueuelen:1000
             RX bytes:9578692 (9.1 MiB)  TX bytes:1042156 (1017.7 KiB)
             Memory:f8c60000-f8c80000
   

9. In the /etc/sysconfig/network-scripts directory, edit the following files to change HWADDR to the value returned in step 8:
   • ifcfg-eth0
   • ifcfg-eth1
   • ifcfg-eth2
   • ifcfg-eth3

   The following example shows the edited ifcfg-eth0 file:

   #### DO NOT REMOVE THESE LINES ####
   #### %GENERATED BY CELL% ####
   DEVICE=eth0
   BOOTPROTO=static
   ONBOOT=yes
   IPADDR=10.204.74.184
   NETMASK=255.255.252.0
   NETWORK=10.204.72.0
   BROADCAST=10.204.75.255
   GATEWAY=10.204.72.1
   HOTPLUG=no
   IPV6INIT=no
   HWADDR=00:14:4F:CA:D9:AE
   

10. Restart the storage server.
11. Activate the grid disks:

    CellCLI> ALTER GRIDDISK ALL ACTIVE
    

    If the Oracle ASM disks were not dropped, then they go online automatically and start being used.

12. Validate the configuration:

    CellCLI> ALTER CELL VALIDATE CONFIGURATION
    

13. Activate Oracle ILOM for ASR.
