Problems with Running the Agent on Multiple Clusters
Running the agent on multiple cluster members can cause problems in operational
ease-of-use. For example, if you make changes with the agent on one cluster member,
those changes are not immediately reflected by the agents on other cluster members,
so what you see in the Navigation Window might not be what you expect. Running the
agent on multiple cluster members is not harmful, but it can be confusing, depending
on your configuration.
The required ACS firmware version for the controller implements a locking
mechanism that prohibits data corruption caused by simultaneous system access,
either from cluster members or standalone systems. Your data integrity is protected.
The following is recommended for running SWCC in a TruCluster Server
environment. The controller recommendations are specific to the HSG80, HSG60, and
HSZ80 controllers:
• Configure your hardware as described in the TruCluster Server Hardware
Configuration manual.
• Use multiple-bus failover mode so that all units are available to both ports of an
HSG80/HSG60/HSZ80 controller.
• Set the HSG80/HSG60 unit offset to 0 for all connections.
• Set the HSG80/HSG60/HSZ80 access path so that the appropriate cluster member
connections are enabled.
• Make sure that the HSG80/HSG60/HSZ80 Command Console LUN (CCL) is
enabled. We recommend that you use the controller in SCSI-3 mode so that the
CCL is always located at LUN0.
• If you use selective storage presentation (SSP) on the HSG80/HSG60 controller,
or zoning on a Fibre Channel switch, remember that this selective view of your
storage is reflected in the Navigation Window.
• Install the SWCC agent on one cluster member. (The SWCC installation script
does not allow you to install it on more than one member at a time.)
• Edit the /sbin/init.d/swcc startup script to probe for a TruCluster Server
environment.
• Use the cluster application availability (CAA) scripts described in this procedure
to start and stop the SWCC agent, and to provide failover for the swcc resource.
