6.4.5 Configuring a Server Group

This section describes how to create a server group and set related parameters. This makes
configuration and management be convenient.
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
load-balance group group-name
A server group is created and the server group view is displayed.
Up to 1024 load balancing groups can be created, including link groups, server groups, and
firewall groups.
By default, no server group is configured.
Step 3 Run:
probe probe-name
A probe of the server group is configured.
By default, no probe is configured for a server group.
Step 4 Run:probe-mode { fail-on-all | fail-on-one }The probe mode is set.
By default, the probe mode is fail-on-one. In fail-on-one mode, a server is considered as Down
when all the probes bound to the server group detect that the server member is in Down state.
When the probe mode is fail-on-one, the server member is considered as Down when a probe
bound to the server group detects that the server member is in Down state.
Step 5 Run:
failaction { purge | reassign }
The action performed when a server fails is set.
By default, no action is taken when a server fails.
If the action is set to purge, when the master server fails, the connections of the master server
are removed and not switched to a backup server. If the action is set to reassign, when the master
server fails, all the connections of the master server are switched to a backup server.
Step 6 Run:
switch-threshold percent1 restore-threshold percent2
The threshold for switching services from the master server to the backup server is set.
