The VMwareDisks agent enables vMotion and VMware Distributed Resource Scheduler (DRS) in VCS clusters configured and deployed on virtual machines in VMware environment.

When a VCS cluster with a shared disk is configured on virtual machines, VMware does not support VMware Distributed Resource Scheduler (DRS) and vMotion. Thus the vMotion and DRS capabilities are compromised. The solution to this issue would be to attach the disk(s) to a single virtual machine at a time in a VCS cluster. In case of a user initiated failover or a fault induced failover, these disks would failover (detach-attach) to the target virtual machine along with the service group. VMwareDisks agent manages the attaching and detaching of the disks to the virtual machines.

To ensure proper functioning of the VMwareDisks agent, verify that the ESX/ESXi host or vCenter user account has administrative privileges or is a root user. If you do not want to use the administrator user account or the root user, create a role with the required privileges for VMwareDisks resource functionality and assign this role to one or more users.

The role assigned to the user account must have the following privileges:

Note that the above list is only illustrative, you can add additional privileges as required.
