Considerations:
•
Wild cards are not applicable to the ALTER SUBSYS command.
•
You may alter only one attribute at a time. To specify values for all three distance
attributes, use three ALTER SUBSYS commands.
•
The ALTER SUBSYS command is relevant only in three-zone 6780 ServerNet
cluster topologies in which some zones are separated by distances greater than 5
kilometers, while other zones are separated by distances of 5 kilometers or less.
In such topologies, ALTER SUBSYS commands must be issued on every node to
configure the zone-to-zone distances attributes.
•
Upon receiving an ALTER SUBSYS command, the node stores the specified zone-
to-zone distance attribute in the External ServerNet SAN Manager configuration
record, which is kept in the System Configuration Database.
•
If you do not specify the distance between nodes, the subsystem infers the
distance from the configuration loaded on the cluster switches.
ALTER SUBSYS Command Examples
The following command specifies that the distance between zone 1 and zone 2 is 300
meters:
-> ALTER SUBSYS $ZZSMN, Z1Z2DIST 300
