Veritas InfoScale component limitations in an ESXi environment
Some limitations apply for using Storage Foundation and Storage Foundation Cluster File System High Availability with VMware ESXi:
Dynamic Multi-Pathing
Dynamic Multi-Pathing (DMP) is supported in the VMware environment. Due to the architecture of VMware, DMP does not perform multi-pathing for the Virtual Machine. However, DMP is an integral part of the data path of Veritas InfoScaleproducts and performs device management tasks such as device discovery and thin reclamation.
See How Veritas InfoScale solutions work in a VMware environment.
Dynamic Multi-Pathing for VMware is a separate component from Veritas that performs storage multi-pathing at the ESXi Hypervisor layer.
See the following web site for more information:

Sharing VMDK files between virtual machines
When sharing VMDK files between virtual machines, SCSI BUS sharing mode for the corresponding SCSI controllers can be set to either "Physical" or "Virtual" modes. Setting this mode to "Physical" causes SCSI reservation conflict and I/O error on DMP. This issue occurs in LVM and raw disks also.
Solution:
Disable simultaneous write protection for the shared disk using the multi-writer flag. The procedure is described in the following VMware Knowledge Base article:
Volume Replicator (VVR) option
VVR is supported inside a Virtual Machine. Keep in mind that VVR can use a significant amount of network bandwidth (depends on the amount of data written to disk) and this can reduce the available network bandwidth for other virtual machines. Since the network card is a shared resource, ensure that enough bandwidth is available to sustain the writes happening to disk.
Veritas File System
All features in Veritas File System are supported in a VMware virtual machine environment.
