VMFS Accessibility on a SAN
Any VMFS volume on a disk that is on a SAN should have VMFS accessibility set to
public or shared. Public, the default and recommended accessibility mode, makes the
VMFS volume available to multiple physical servers, and to the virtual machines on
those servers. With VMFS-2 volumes, public access is concurrent to multiple physical
servers, whereas for VMFS-1 volumes, public access is limited to a single server at a
time. For more information on configuring ESX Server with a SAN, see Using Storage
Area Networks with ESX Server on page 315.

Note: You cannot change VMFS accessibility if there are any open files on the
