8. 增加数据盘和REDO盘
In this section, the database disks for data and redo logs are added to the virtual machine RAC nodes in the following way: ? ? ? ?
Data and redo datastoresare created with the assigned LUNs, and corresponding VMDKs are added tothe virtual machine RAC1. The SCSI controller type is set to VMware Paravirtual.
The same Data and Redo VMDKs are added to the remaining node(RAC2) by selecting the VMDKs that were created for RAC1. Again, the SCSI controller type is set to VMware Paravirtual. The added disks are formatted using the Linux fdisk utility. Configuration parameters are added for each virtual machine.
The procedures in this section describe the steps needed for one virtual machine. Repeat the steps in this section for each of thefour virtual machines named RAC1,RAC2. To add DATA or REDO disks to the first virtual machine 1. In vSphereClient, select the virtual machine.
2. Right-click the name of the virtual machine and select Edit Settings to display the Virtual Machine
Properties pane. 3. Click Addto display the Add Hardware wizard.
4. In the Add Hardware wizard select Hard Disk for the Device Type, and click Next.
5. In the Disk section of the Select a Disk page, select Create a new virtual disk. Set the disk size to
1000GB for DATA or 900GB for REDO, and select the Support clustering features such as Fault Tolerance check box. Also, for vSphere 5, in the Disk Provisioning section, select Thick Provision Eager Zeroed. Select DATA01 for DATA, or REDO01 for REDO to specify a datastore. Click Next. 6. On the Compatibility Mode page, click Next.
7. On the Advanced Options page, in the Virtual Device Node section, select SCSI (1:1) for REDO ,
or SCSI(2:0) for DATA.Set the Mode to Independent. Click Next 8. On the Ready to Complete page, click Finish. 9. Click OK.
10. Repeat steps 1 through 9 for all the DATA datastores.Change step 7 to use SCSI (2:1)/SCSI
(3:0)/SCSI (3:1)for the other DATA datastores.

To set the SCSI controller type to paravirtual
1. Select the virtual machine that was selected in the preceding step 1.
2. Right-click the name of the virtual machine and select Edit Settings to display the Virtual Machine
Properties pane. 3. In the device list, select SCSI controller 1.
4. In the SCSI Bus Sharing section, select None, keep the default selection. 5. In the SCSI Controller Type section, click Change Type. 6. Select VMware Paravirtual. 7. Click OK, and click OK again.
To format disks using the Linux fdisk utility 1. Follow the steps in Section 5.3 to format one disk. 2. Repeat, using fdisk to format each disk.
To add configuration parameters for each Oracle RAC virtual machine
Add Configuration parameters for each Oracle RAC virtual machine as perDisabling simultaneous write protection provided by VMFS using the multi-writer flag (http://kb.vmware.com/kb/1034165). To add configuration parameters to the virtual machines 1. In vSphereClient, select a virtual machine.
2. Right-click the name of the virtual machine and select Edit Settings to display the Virtual Machine
Properties pane. 3. Click the Options tab, click Advanced, and click General. 4. Click Configuration Parameters.
5. On the Configuration Parameters page, add rows and entries for the shared disks in the virtual
machine’s configuration parameters as shown in the following screenshot.
