4. save scsirouter scsi2 bootconfig — Save the current SCSI
routing instance configuration, including the primary setting, and circulate the
changed configuration around the cluster.
5. failover scsirouter scsi2
— Failover the desired SCSI routing
instance,
scsi2.
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
that the SCSI routing instance to be moved is indeed running on storage
router,
StorageRouterSys2.
3. failover scsirouter scsi3 to StorageRouterSys1
—
Failover the desired SCSI routing instance,
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: Because scsi3 has no primary setting, it will remain running on
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.
