Agent Running on Multiple Nodes Concurrently
Is it desirable to have the Agent running on multiple nodes concurrently? 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 a new locking feature built into the V2.2 Agent and
the ACS V8.5 firmware.
2. Running the SWCC Agent on a cluster.
• Agent Installation in a Cluster environment
Agent Installation in a cluster environment consists of installing the Agent on all nodes that make
up the cluster. If the cluster contains four nodes, install the SWCC Agent on each of the four
nodes.
Important Note:
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, do the following.
• Run the“swcc_config” utility. Type in /usr/opt/SWCC220/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. Select Option 7 and answer “yes” to the question: “Do you want to kill and disable
the agent NOW?”
• Quit the swcc_config utility.
Please realize that, in general, the procedure above is run for each node that you do NOT want
running the Agent.
3. Running the SWCC Agent under ASE Services.
• Short ASE Service overview
• Creating Start/Stop scripts
• Creating the ASE Service by running “asemgr” utility
• Checking for proper behavior
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.
