Vmware Cluster Configuration & Shared Storage Configuration.

PART II - Vmware Cluster Configuration & Shared Storage Configuration.

Continued from: Now we have two operating System (RAC1 & RAC2) and Operating Sytem name called (Linux1 & Linux2).


Now we have two guest operating system (say linux1 & linux2 ).


Vmware Cluster Configuration:


This RAC setup we are doing throw Vmware. So our cluster service managed by Vmware only. In both virtual machine we have .VMX file (this file manageing Vmware - Guest Operating System)

Here we need to edit/add some parameter.


ie..


config.version = "8"
virtualHW.version = "4"
numvcpus = "2"
scsi0.present = "TRUE"
scsi0.virtualDev = "lsilogic"
memsize = "1024"
scsi0:0.present = "TRUE"
scsi0:0.fileName = "Red Hat Enterprise Linux 4.vmdk"
ide1:0.present = "TRUE"
ide1:0.fileName = "auto detect"
ide1:0.deviceType = "cdrom-raw"
floppy0.present = "FALSE"
Ethernet0.present = "TRUE"
displayName = "SR2"
guestOS = "rhel4"
priority.grabbed = "normal"
priority.ungrabbed = "normal"

scsi0:0.redo = ""
ethernet0.addressType = "generated"
uuid.location = "56 4d e9 4c 35 1c ad eb-8c d0 95 c3 25 fa 60 8d"
uuid.bios = "56 4d e9 4c 35 1c ad eb-8c d0 95 c3 25 fa 60 8d"
ide1:0.autodetect = "TRUE"
ethernet0.generatedAddress = "00:0c:29:fa:60:8d"
ethernet0.generatedAddressOffset = "0"

Ethernet1.present = "TRUE"

ethernet1.addressType = "generated"
ethernet1.generatedAddress = "00:0c:29:fa:60:97"
ethernet1.generatedAddressOffset = "10"

Scsi1.present = "TRUE"
Scsi1.virtualDev = "lsilogic"
Scsi1.sharedBus = "VIRTUAL"

disk.locking = "FALSE“
diskLib.dataCacheMaxSize = "0"
diskLib.dataCacheMaxReadAheadSize = "0"
diskLib.dataCacheMinReadAheadSize = "0"
diskLib.dataCachePageSize = "4096"
diskLib.maxUnsyncedWrites = "0“

scsi1:1.present = "TRUE"
scsi1:1.fileName = "H:\Virtual Machines\Shared-Vmware\OCR.vmdk"
scsi1:1.mode = "independent-persistent"
scsi1:1.deviceType = "disk"

scsi1:2.present = "TRUE"
scsi1:2.fileName = "H:\Virtual Machines\Shared-Vmware\VOT.vmdk"
scsi1:2.mode = "independent-persistent"
scsi1:2.deviceType = "disk"

scsi1:3.present = "TRUE"
scsi1:3.fileName = "H:\Virtual Machines\Shared-Vmware\ASM.vmdk"
scsi1:3.mode = "independent-persistent"
scsi1:3.deviceType = "disk"

scsi1:1.redo = ""
scsi1:2.redo = ""
scsi1:3.redo = ""

Ps: The above bold are very important vmware cluster configuration values.

Make sure the above bold are available/configured both guest operating system (linux1 & linux2)

Shared Storage Configuration:

Virtual Disk on Host	Virtual Disk on Guest	Virtual Device Node	Size (Gb)	Description
D:\Virtual Machines\Linux1\Red Hat Enterprise Linux 4.vmdk	/dev/sda	SCSI 0:0	40	/ mount point
H:\Virtual Machines\Shared-Vmware\OCR.vmdk	/dev/sdb1	SCSI 1:0	15	Raw disk
H:\Virtual Machines\Shared-Vmware\CRS.vmdk	/dev/sdc1	SCSI 1:2	15	Raw disk
H:\Virtual Machines\Shared-Vmware\ASM.vmdk	/dev/sdd1	SCSI 1:3	15	Raw Disk

This T abler column will explain about shared storage configuration & Architecture.
