OUT file-spec
causes any SCF output for this command to be directed to the specified file.
attribute-spec
contains one of the following attribute name and value combinations:
[ , Z1Z2DIST { 1 - 15000 } ]
[ , Z1Z3DIST { 1 - 15000 } ]
[ , Z2Z3DIST { 1 - 15000 } ]
Z1Z2DIST
Specifies the distance, in meters, between zone 1 and zone 2. This attribute is
relevant only in three-zone 6780 ServerNet Cluster topologies in which the

greater than 5 km in other cases. Currently, the supported distance range is 1
to 15000 meters.
Z1Z3DIST
Specifies the distance, in meters, between zone 1 and zone 3. This attribute is

Z2Z3DIST
Specifies the distance, in meters, between zone 2 and zone 3. This attribute is
