Caution Retaining SCSI routing instance configuration data could provide unexpected results.
Changing the cluster name, thereby joining another cluster, has the following effects on its existing
configurations and operations:
• All SCSI routing instances are failed over to another member in the original cluster.
• All applications are stopped.
• The cluster name is changed.
• If you choose to retain data, any unsaved cluster configuration information is saved.
• The system reboots. Configuration information is exchanged and the storage router learns AAA,
access list, password, SCSI routing instance and VLAN configuration information from the cluster.
All of the original SCSI routing instances appears in the new cluster, unless you chose to delete
rather than retain data.
• Access lists that existed on the storage router prior to joining the new cluster are always deleted. To
preserve an existing access list and make it available to the new cluster, you must save the access
list to a configuration file before issuing the setup cluster command. Make the saved configuration
file available to the storage router currently performing access list maintenance functions for the
cluster (via the copy command), and then restore the saved access list to the new cluster from that
configuration file. See Chapter 10, “Configuring a High Availability Cluster,” for more information
about configuring the storage router to participate in a cluster.
• For cases where the names of SCSI routing instances are duplicated within the new cluster (meaning
instances of the same name are already running in the new cluster), configuration data from the old
cluster is deleted in favor of what is currently running in the new cluster.
Only one setup wizard can be active at any given time. Multiple users cannot run multiple setup wizards
concurrently.
Use the optional parameter arguments to run the setup cluster wizard from a command script. All
parameters required by the wizard must be included. The setup cluster wizard will not complete unless
all parameters are passed.
Note If too many parameters are passed, the setup cluster wizard will ignore the extra parameters and may
complete. If a parameter is not in the correct format or is otherwise invalid, the next parameter is used
to attempt to fulfill the prompt. In either case, unexpected results could occur. Always check the output
from a setup cluster command when using the parameter arguments.
Examples The following shows example output and input for the setup cluster command:
[SN5428-2_PR]# setup cluster
The system has the ability to run in a standalone or clustered state.
By default, the system will run in a clustered state and communicate
with other SN5428-2s in the same cluster. If a single SN5428-2 is deployed
and you don't intend to add a second SN5428-2 to provide high availability
features in a clustered configuration, you should configure the SN5428-2 in
standalone mode. Enter CTRL-C at any prompt to cancel changes and return
to the command prompt.
