SWCC Agent in TruCluster Environment
C–2 HSG80 ACS Solution Software Version 8.7 for Compaq Tru64 UNIX Installation and
Configuration Guide
Running the SWCC Agent on a V4.0G Cluster
This first section presents an example of how to set up the StorageWorks Command
Console (SWCC) Agent on Tru64 UNIX V4.0G running TruCluster V1.6. It acts as a
guide for setting up the Agent for High Availability.
The best way to accomplish high availability failover capability is by creating an ASE
service to accomplish a failover.
StorageWorks recommends that the Agent run on only one node in a cluster. However,
if the user is running HSG80s with ACS firmware V8.5 or higher EXCLUSIVELY, it
is possible to run more then one Agent concurrently in a cluster. This is due to the
locking feature built into the Agent and the ACS V8.5 and higher firmware.
IMPORTANT: When installing the SWCC Agent in a cluster environment make sure that all RAID arrays have
the same name on all nodes where the kit is installed. This will avoid problems with multiple
Clients not being able to find certain arrays because they are named differently on different
nodes.
Insure that the Agent runs on only one node in the cluster. The exception to this, as
previously stated, is where the cluster environment contains HSG80s and NOT a mix
of HSGs and HSZs. To run the Agent on one member of a multi-node cluster, perform
the following procedure.
NOTE: In general, this procedure is run for each node that you do NOT want running the Agent.
1. Run the swcc_config utility by typing: /usr/opt/SWCC520/scripts/swcc_config on
each node where the SWCC Agent is installed. Do not run the utility on the one
node that you want to run the Agent.
2. Select Option 7.
3. Answer Yes to the question: “Do you want to kill and disable the agent NOW?” to
quit the swcc_config utility.
Running the SWCC Agent under ASE Services
In a TruCluster environment, use ASE Services to monitor the state of an application.
ASE Services can be used to automatically failover an application in the event that the
node running the application fails. Create this “Service” by running the “asemgr”
utility and answering the appropriate questions.
There are two steps to creating an ASE Service:
1. Create the Start/Stop scripts.
