Chapter 10 Configuring a High Availability Cluster
Creating a Cluster
Adding a Minimally Configured SN 5428-2 Storage Router
To add a minimally configured SN 5428-2 to an existing cluster, perform the following steps:
Step 1 Run the setup cluster configuration wizard.
• When prompted to select HA configuration mode, choose clustered.
• When prompted for cluster name, enter the name of the existing cluster.
• When prompted, enter the HA IP address for the SN 5428-2. The HA interface for each storage
router in a cluster must be on the same IP subnet.
• When prompted to retain or delete “scsirouter” instances, enter delete. Deleting means that any
existing SCSI routing instances will be deleted from this SN 5428-2. (Since this is a minimally
configured SN 5428-2, there should be no SCSI routing instances to delete.)
• Enter yes to confirm your changes. The storage router automatically reboots.
Step 2 When the storage router restarts, it communicates with other member of the cluster to obtain current
cluster configuration information. Once the storage router is completely restarted, verify the new cluster
configuration. Issue the show cluster command to verify the cluster name and confirm that the
SN 5428-2 is exchanging heartbeats with the other member of the cluster.
Step 3 To verify that both storage routers in the cluster include the same cluster configuration elements, issue
the following commands from the principal storage router in the cluster:
• show aaa
• show accesslist all
• show scsirouter all from bootconfig
• show vlan
• show vtp
Issue the same commands from the SN 5428-2 just added to the cluster. The displays should be the same.
Step 4 Complete additional system configuration of the SN 5428-2 just added to the cluster, as needed. For
example:
• Use the setup netmgmt configuration wizard to configure the storage router for network
management via SNMP.
• Use the setup time configuration wizard to configure the storage router date and time, and optional
NTP server information.
• Use the CLI or GUI to configure CDP and logging.
• If you are participating in Fibre Channel switched fabric zoning with the storage router, configure
for zoning using the procedures described in Chapter 5, “Configuring Fibre Channel Interfaces.”
Step 5 Save any changes to the configuration by issuing the appropriate save command with the bootconfig
keyword, which updates the bootable configuration for the SN 5428-2 and notifies all storage routers in
the cluster of the configuration changes.
Step 6 (Optional) To divide the workload between the storage routers in the cluster, you can manually fail over
selected SCSI routing instances using the failover scsirouter command. See Chapter 11, “Maintaining
and Managing the SN 5428-2 Storage Router,” for more information about failing over SCSI routing
instances.
