Configuring VMWare virtual Networks:
--------------------------------------------------------------
Start --> Programs --> VMware --> VMware GSX Server --> Manage Virtual Networks
From Virtual Network Editor , Select Host Virtual Network Mapping：
The public address is using "Bridged" mode to utilize the physical subnets (172.16.2.0/24, on same subnet with the host machine.
VMnet1's subnet address is 192.168.235.0/24 (use "host-only" mode) - as private address for the 2 nodes.
Installing/Preparing Guest machine (SuSE10.1)
-----------------------------------------------------------------------------
Creating Guest machine (SuSE10.1) in VMWare
-----------------------------------------------------------------------------
1. Open VMware Virtual Machine Console
2. Click New Virtual Machine
3. Select the Appropriate Configuration：
Select Custom， click ［Next］
4.Select a Guest Operating System：
Select Linux，Version SuSE Enterprise Linux， click ［Next］
5.Name the Virtual Machine：
SLES101, location d:\sles101 ， click ［Next］
6.Set Access Rights：
Use default ， click ［Next］
7.Startup / Shutdown Options：
Use default, User that powers on the virtual machine， click ［Next］
8.Memory for the Virtual Machine：
1024MB， click ［Next］
9.Network Type：
select Do not use a network connection， click ［Next］( configure later )
10.Select I/O Adapter Types：

www.ixdba.net

select LSI Logic， Click ［Next］
11.Select a Disk：
select Create a new virtual disk， click ［Next］
12.Select a Disk Type：
select SCSI， click ［Next］
13.Specify Disk Capacity：
Enter 8GB， select Allocate all disk space now， deselect Split disk into 2GB files，
click ［Next］
14.Specify Disk File：
d:\sles101\system.vmdk， click ［Finish］
15.Info：
Creating pre-allocated virtual disk...
16 .Hardware Type：
select Ethernet Adapter， click［Next］
17 .Network Type：
select Custom， select "Bridged" ，Connect at power on， click ［Finish］
18. add one more NIC：
click ［Add］
19 .Hardware Type：
select Ethernet Adapter， click ［Next］
20 .Network Type：
select Custom， "Host-only" ，Connect at power on， click ［Finish］
22. Exit VMware Virtual Machine Console：
I will use the first node to clone the second node.
------------------------------------------
Create additional disks ：
------------------------------------------
1. On Window Host machine, Open Command Prompt。
2. Change to GSX Installation directory, c:\program files\vmware\vmware gsx server：
3. Run DOS command to create OCR + CRS voting disks,
vmware-vdiskmanager -c -s 500Mb -a lsilogic -t 2 d:\sles101\ocr.vmdk
vmware-vdiskmanager -c -s 500Mb -a lsilogic -t 2 d:\sles101\css.vmdk
[OCR and CSS partition could be on the same virtual disk, and you can also create mirror disk (1 for OCR, 2 for CSS) if neccessary, each OCR or CSS partition need >256MB disk space.]

4. Create 1 Oracle product disk >4GB, used for local disk on both nodes
vmware-vdiskmanager -c -s 4Gb -a lsilogic -t 2 d:\sles101\u01.vmdk
5. Create 4 ASM disks for Oracle data & flash recovery area：
vmware-vdiskmanager -c -s 2Gb -a lsilogic -t 2 d:\sles101\asm1.vmdk
vmware-vdiskmanager -c -s 2Gb -a lsilogic -t 2 d:\sles101\asm2.vmdk
vmware-vdiskmanager -c -s 2Gb -a lsilogic -t 2 d:\sles101\asm3.vmdk
vmware-vdiskmanager -c -s 2Gb -a lsilogic -t 2 d:\sles101\asm4.vmdk
6. Edit (do not use notepad) d:\sles101\system.vmx and d:\sles102\system.vmx (after cloned from sles101), add the following lines:
scsi1.present = "TRUE"
scsi1.virtualDev = "lsilogic"
scsi1.sharedBus = "virtual"
scsi1:1.present = "TRUE"
scsi1:1.mode = "independent-persistent"
scsi1:1.filename = "d:\sles101\ocr.vmdk"
scsi1:1.deviceType = "plainDisk"
scsi1:2.present = "TRUE"
scsi1:2.mode = "independent-persistent"
scsi1:2.filename = "d:\sles101\css.vmdk"
scsi1:2.deviceType = "plainDisk"
scsi1:3 .present = "TRUE"
scsi1:3.mode = "independent-persistent"
scsi1:3.filename = "d:\sles101\asm1.vmdk"
scsi1:3.deviceType = "plainDisk"
scsi1:4 .present = "TRUE"
scsi1:4.mode = "independent-persistent"
scsi1:4.filename = "d:\sles101\asm2.vmdk"
scsi1:4.deviceType = "plainDisk"
scsi1:5.present = "TRUE"
scsi1:5.mode = "independent-persistent"
scsi1:5.filename = "d:\sles101\asm3.vmdk"
scsi1:5.deviceType = "plainDisk"
scsi1:6.present = "TRUE"
scsi1:6.mode = "independent-persistent"
scsi1:6.filename = "d:\sles101\asm4.vmdk"
scsi1:6.deviceType = "plainDisk"
disk.locking = "FALSE"
diskLib.dataCacheMaxSize = "0"
diskLib.dataCacheMaxReadAheadSize = "0"
diskLib.dataCacheMinReadAheadSize = "0"
diskLib.dataCachePageSize = "4096"
diskLib.maxUnsyncedWrites = "0"
save and exit.

[If the vitual machines will be installed on VMWare ESX server, use "LSI Logic" for the SCSI Controller type. If you use "Bus Logic", the drivers could not be loaded and no hard drive will be located for installation.]

Install SuSE Linux 10.1 (sles) on first node
--------------------------------------------------------------------
Please refer to the following Novell official website for the installation guide:
Installing Oracle10g R2 Database on SLES10 for i386 - step by step
Partition Settings
For "partitioning" of the Installation Settings screen, create LVM partitions for "/", "/tmp", swap,"/u01"(the oracle product location). Create with this sequence: PV->VG->LV
Create Physical Volume from raw partition (primary partition) first, then create new Volume Group and add Physical Volumes to the group, at last mount the Volume Group to the mounting points with format option.
The reason to use LVM is that it is easy to extend the size in case not sufficient later. For example, the following results showed that the "swap" space was extended from 1GB up to 1.89GB by adding 2 partitions (/dev/sdc1 and /dev/sdc2) to the first partition (/dev/sda3) which are all in the VG "swapvg".
