Add a shared disk for Oracle RAC under VMware Server

In the Oracle RAC environment under VMWare, multi-path images of OCR or votingdisk are not enough for shared storage or need to be added to a new shared disk, we can add shared storage through the command line under VMWare, and then append these new disks to the virtual machines one by one. The following is a detailed description.

1. Add a virtual disk # Here we will add two shared disks for the virtual machine # One is to add an OCR image and the other is to supplement the situation where the ASM disk is insufficient. c: \ Users \ Robinson. cheng> Cd c: \ Program Files (x86) \ VMware Server c: \ Program Files (x86) \ VMware Server> vmware-vdiskmanager.exe # command line usage help information c: \ Program Files (x86) appears without adding any parameters) \ VMware Server> vmware-vdiskmanager.exe-C-S 200 MB-A lsilogic-T 2 C: \ myvm \ sharedisk \ ocrmirror. vmdk creating disk 'C: \ myvm \ sharedisk \ ocrmirror. vmdk 'create: 100% done. virtual Disk creation successful. c: \ Program Files (x86) \ VMware Server> vmware-vdiskmanager.exe-C-S 2000 MB-A lsilogic-T 0 C: \ myvm \ sharedisk \ asm_data_new.vmdk creating disk 'C: \ myvm \ sharedisk \ asm_data_new.vmdk 'create: 100% done. virtual Disk creation successful. c: \ Program Files (x86) \ VMware Server> Cd c: \ myvm \ sharedisk> dir asm_data_new * ocrmi * volum E In drive C has no label. volume serial number is your directory of c: \ myvm \ sharedisk 06/01/2013 PM 327,680 your directory of C: \ myvm \ sharedisk 06/01/2013 PM 209,715,200 ocrMirror-flat.vmdk 06/01/2013 PM 425 ocrmirror. vmdk 3 file (s) 210,043,305 bytes 0 Dir (s) 152,651,186,176 bytes free 2. append the virtual disk to the virtual machine. On the virtual machine interface, select the virtual machine to add the disk, and click Add hardware ", click "Hard Disk" and select "Use a Exi Sting Virtual Disk ". Select the newly created vmdk File Based on the path, ocrmirror. vmdk, and "independent" for disk mode ". For the virtual device node, select sci2: 0 (scsi0 and scsi1 are used to avoid SCSI bus faults. If you select the remaining devices on scsi0 and scsi1, You need to reconfigure ASM. Because the disk SDA, SDB, and SDC are allocated based on the SCSI sequence and the nodes above it. Other Newly Added disks are processed as examples. Add these new disks to another host in the same way # Author: Robinson # blog: http://blog.csdn.net/robinson_06123133 modify the virtual machine configuration file and edit the configuration files of each virtual machine. at the end of vmx, you can see that the newly filled disk has already appeared in the configuration file. Modify the sharedbus entry of the newly added SCSI bus to virtual. In this example, scsi2.sharedbus = "virtual" is followed by adding the following items to the configuration file. Note the scsix: Y representation. X indicates the number of buses, and y indicates the number of devices on the bus. 0 indicates the first device, 1 indicates the second device, and so on. Sci2: 0. devicetype = "disk" sci2: 0. redo = "" sci2: 1. devicetype = "disk" sci2: 1. redo = "" 4. Configure the bare device and ASM to start the VM and then perform fdisk on the Newly Added Disk on any VM. Raw devices need to be configured for the OCR or votedisk used as an image. The OCR and votingdisk can be stored in ASM at 11g RAC. For SuSE Linux, refer to: SuSE Linux 10 configure raw device (raw devices) http://blog.csdn.net/robinson_0612/article/details/7997335 for ASM disks that are used to store data, you need to use asmlib for configuration. For ASM configuration, see: Creating an ASM instance and an ASM database http://blog.csdn.net/robinson_0612/article/details/6080659
