Configuring a High Availability Cluster

5. Add SvSys2 to the new cluster named Cluster1, using the Setup Cluster
Configuration Wizard. When prompted, enter retain to share the existing
SCSI routing instances across the cluster.
6. Use the show cluster command to verify the cluster name after
StorageRouterSys2 reboots. Verify that the defined SCSI routing instances
were retained, using show scsirouter command.
7. Restore any access lists saved in Step 3 using the
restore accesslist from command. Access lists can only be
manipulated from the first storage router in a cluster, so these commands must
be issued from the system
StorageRouterSys1. (Optional)
8. Save all configuration information on system
StorageRouterSys1 by issuing a
save all bootconfig command, which updates the bootable
configuration of all storage routers in the cluster. (Optional)
9. Verify that all SCSI routing instances are active using the
show scsirouter stats command on both storage routers.
Changing Clusters
In some situations, you may need to move the storage router from one cluster to
another cluster. Moving a fully configured storage router from one cluster to
another is more complex than simply adding the storage router to a cluster.
Advanced planning is required.
To successfully move the storage router from one cluster to another:
1. Verify that the storage router to be moved has the same hardware
configuration as the other storage routers in the cluster you are planning to
join. Each storage router in the cluster must have connectivity to the same IP
hosts and Fibre Channel storage. All management interfaces for the storage
routers within a cluster must be on the same IP subnet, and all HA interfaces
for the storage routers within a cluster must be on the same IP subnet.
However, the management interfaces must be on a different IP network than
the HA interfaces.
2. Decide if you need to retain any SCSI routing instances defined on the storage
router joining the cluster. Retaining data means all SCSI routing instances
existing on the storage router joining the cluster will be added to those already
defined for the cluster. If the existing instances are not retained, they are
deleted.
