Veritas InfoScale™ 7.3.1 Virtualization Guide - Linux on ESXi

To map the VMDKs to each VM

1. Shut down the VM.
2. Select the VM and select Edit Settings....
3. Select Add , select Hard disk and click Next.
4. Select Use an existing virtual disk and click Next.

5. Select Browse and choose DS1 data store.
6. Select the folder cfs0 and select shared1.vmdk file and click Next.
7. On Virtual Device Node select SCSI (1:0)

   and click Next.

8. Review the details to verify they are correct and click Finish.
9. Since this is the first disk added under SCSI controller 1, a new SCSI controller is added.

   Modify the type to Paravirtual, if that is not the default, and check that SCSI Bus Sharing is set to None, as this is key to allow vMotion for the VMs.

10. Follow steps 3 to 8 for the rest of disks that will be added to each of the VMs.

    For the example configuration, the parameters for steps 5-7 are given in the table below:

    Data Store	VMDK Name	Virtual Device
    DS1	cfs0/shared1.vmdk	SCSI 1:0
    DS2	cfs0/shared2.vmdk	SCSI 1:1
    DS3	cfs0/shared3.vmdk	SCSI 1:2
    DS4	cfs0/shared4.vmdk	SCSI 1:3
    DS5	cfs0/shared5.vmdk	SCSI 1:4

    The final configuration for the first node of the example cluster (cfs01):

    Now follow the same steps for each node of the cluster and map each VMDK file to the VM following the instructions above. Once all the steps are completed, all the VMs should have access to the same VMDK files. Note that at this point, all the VMs are still powered off and that multi-writer flag has not been enabled yet (it will be done in the next step). Any attempt to power on the VMs in this state will prevent a second VM start because it will violate the restrictions to access a VMDK by only a host at a time.
