Managing Network Clients Connected to a Cluster
An important aspect of managing network clients is to inform users that their
applications are now running on a cluster. Because users will experience some
disruption of service and possibly a performance degradation during failover, they
might become concerned about the availability and stability of their applications. As
the cluster is initially brought into a production environment, it might be beneficial to
describe in a memorandum the effects a cluster will have on the users’ information
systems needs.
When a failover or failback event occurs, users cannot access their application or
data. When users have been properly forewarned of the effects of operating in a
clustered environment, they will more readily recognize when a failover or failback
event is occurring or has occurred. Most will wait a few seconds to several minutes
before trying to reconnect to their application or data.
Remotely Managing a Cluster
Both Compaq Insight Manager 7 and Microsoft Cluster Administrator can be run
from network client machines. Each program allows you to monitor multiple clusters
from a single remote client. See the corresponding documentation to determine how
to set up and configure each of these programs to run remotely.
Cluster Events
Cluster events are logged in the Microsoft operating system Event Log. Use the
Microsoft operating system Event Viewer to view the data in the Event Log.
