scsirouter failover
scsirouter failover
To build a list of storage routers to be used for failover purposes, use the scsirouter failover command.
scsirouter name failover {primary | secondary} sysname
Syntax Description
Defaults None. By default, the HA failover list is not populated.
Command Modes Administrator.
Command History
Usage Guidelines Use the scsirouter failover command to build a list of storage routers that will be used during the
failover process. If the specified SCSI routing instance fails over, the cluster attempts to start running
the instance on the storage router designated as the primary in the HA failover list. If that storage router
cannot run the SCSI routing instance, the cluster will attempt to start the instance on the storage router
designated as the secondary in the HA failover list.
If there is no primary or secondary storage router on the HA failover list when the SCSI routing instance
fails over, the cluster uses normal failover algorithms to determine where the SCSI routing instance
should run.
The storage routers specified as primary and secondary should be active in the cluster when the
command is issued. If the specified storage router is not currently active in the cluster, the setting will
not take effect until the node is added to the cluster and the SCSI routing instance is restarted.
Use the clear scsirouter failover command to remove the current primary or secondary storage router
from the HA failover list.
Note This command causes the SCSI routing instance configuration information to be saved and all nodes in
the cluster to be updated.
name The name of the SCSI routing instance.
primary sysname The name of the storage router in the cluster. In case of failure, the specified
SCSI routing instance will be failed over to this storage router.
secondary sysname (Optional) The name of the storage router in the cluster. If the primary
storage router in the list cannot run the SCSI routing instance, it will be
failed over to this storage router.
Note Because a high availability cluster consists of two storage routers,
this parameter is not used.
