This is a useful resource: http://www.bakercomputeranddata.com/doc/vendors/emc/emc-docs/ECC5.2/help/ecc/symm_mgr/cfgmn_pd_setting_port_flags.htm.

You need the following director bits set for Windows/VMware. Nothing extra required for Windows or VMware clusters.
Enable Auto Negotiation (EAN)
Enable Point-to-point (PP)
Unique World Wide Name (UWN)
Common Serial Number (C)
SCSI 3 (SC3)
Common Serial Number (C) 4
Disable Queue Reset on Unit Attention (D)
Enable Volume Set Addressing (V)
SCSI-2 Compliance (iSCSI) (SPC-2)

There are some additonal settings for Sun etc clusters - see the link above.

VCS = Veritas Cluster Server? Is that correct?

The port flag settings are as above. You've got a bit of work to do with VCS though: http://sfdoccentral.symantec.com/sf/5.1/windows/pdf/VCS_SRDF_Agent.pdf
