Command History
Usage Guidelines At any given time, a SCSI routing instance can run on only one node in a cluster. If a SCSI routing
instance has the primary attribute set, the specified storage router will take over running that instance
upon system restart or whenever target and critical resources are available.
If the primary attribute is not set, the SCSI routing instance continues running on the node where it was
started until it is explicitly stopped (via a no scsirouter enable command), it automatically fails over to
another node in the cluster because targets or critical resources are unavailable, or an explicit
failover scsirouter command is issued. This is the default behavior.
Use the scsirouter primary command if you always want the specified SCSI routing instance to run on
a specific storage router in a cluster whenever that node is available (assuming target and critical
resources are available). Use the clear scsirouter primary command to remove the currently configured
primary value for the named SCSI routing instance.
Note Setting the primary attribute saves the SCSI routing instance configuration and circulates those changes
to the high availability cluster. If the specified storage router is available to the cluster and has all target
and critical resources available, the SCSI routing instance will be immediately failed over. If the
specified storage router is not available to the cluster, failover will occur as soon as that storage router
becomes available to the cluster (assuming target and critical resources are available).
See Chapter 10, “Configuring a High Availability Cluster,” and Chapter 11, “Maintaining and Managing
the SN 5428-2 Storage Router,” for more information about HA, cluster configuration, and managing
SCSI routing instances in a cluster environment.
name The name of this SCSI routing instance.
