Configuring HA HP CIFS
Chapter 7154
An “active-standby” High Availability configuration is a configuration
where, under normal conditions, one node of the MC/ServiceGuard
cluster is running the MC/ServiceGuard package and one or more other
nodes are in a “wait” mode, waiting to run the package if anything goes
wrong on the first node. Only one node can run the package at any given
time. Hence the names in this type of HA configuration are: “active” for
the first node and “stand by” for the other node(s).
An “active-active” High Availability configuration is a configuration
where, under normal conditions, both (or all) of the MC/ServiceGuard
cluster nodes are running similar MC/ServiceGuard packages at the
same time. If one of the nodes fails, one of the other nodes has to start
doing the work that the failed node had been doing. Both nodes are
normally actively working. Neither one is standing by idle, waiting for a
failure to occur. In our example, both MC/ServiceGuard cluster nodes
normally are running HP CIFS Servers.
This chapter includes complete descriptions of both types along with the
steps required to configure each one.
