Maintaining and Managing the Storage Router
4. save scsirouter scsi2 bootconfig — Save the current SCSI
5. failover scsirouter scsi2 — Failover the desired SCSI routing
Once the failover is complete, establish a Telnet session to StorageRouterSys2 and
verify — using the show scsirouter scsi2 command — that the SCSI
routing instance, scsi2, is now running on StorageRouterSys2 and that
StorageRouterSys2 is designated as the primary storage router for that instance.

Failover for Distribution Purposes

In the example cluster scenario previously described, there is a significant
increase in traffic for SCSI routing instance, scsi4, and as a result, you decide to
distribute all of the other instances (scsi1, scsi2, and scsi3) to the
StorageRouterSys1 storage router. StorageRouterSys1 is already running scsi1
and scsi2.
The following procedure moves the SCSI routing instance, scsi3, to
StorageRouterSys1. The commands in this procedure are issued from a CLI
session from storage router, StorageRouterSys2:
1. enable — Enter Administrator mode.
2. show cluster or show scsirouter scsi3 stats — Verify
3. failover scsirouter scsi3 to StorageRouterSys1 —
Once the failover is complete, establish a Telnet session to StorageRouterSys1 and
verify — using the show scsirouter command — that instances, scsi1,
scsi2, and scsi3, are now running there.
Note:
StorageRouterSys1 until it is explicitly stopped or failed over, or until it automatically
fails over because an interface is unavailable or a software or hardware problem
occurred.

that the SCSI routing instance to be moved is indeed running on storage

Failover the desired SCSI routing instance, scsi3, to StorageRouterSys1.
Because scsi3 has no primary setting, it will remain running on
