The method used to determine which ports are used by VVR depends on the version of SFW (Storage Foundation for Windows) is installed.

For SFW 4.3 and later Vrport can be used to provide a list of ports that are being used for replication.

vrport

data=0-0
heartbeat=4145
vradmind=8199
vxrsyncd=8989

Ensure that none of the ports listed are being filtered or blocked.

Note: Data uses a range of ports. "0=0" is the default value. This indicates a range from port 49152 and up.


For SFW 4.2 and earlier the values of heartbeat, vradmind and vxrsyncd are stored under the following registry keys:

HKEY_LOCAL_MACHINE\SOFTWARE\VERITAS\VxSvc\CurrentVersion\constants\portNumbers\CONNECTIONSERVER
HKEY_LOCAL_MACHINE\SOFTWARE\VERITAS\VxSvc\CurrentVersion\constants\portNumbers\VRAS
HKEY_LOCAL_MACHINE\SOFTWARE\VERITAS\VxSvc\CurrentVersion\constants\portNumbers\VXRSYNC

Note:  CONNECTIONSERVER = heartbeat
          VRAS = vradmin
          VXRYNC = vxrsyncd

The range for data is specified under the following registry keys:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\vxio\VVRParams\PortHigh
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\vxio\VVRParams\PortLow

Ensure that none of the ports listed are being filtered or blocked.

Note: Data uses a range of ports. The default values for PortHigh and PortLow is 0. This indicates a range from port 49152 and up.
