Chapter 12 Command Line Interface Reference
interface ha ip-address
interface ha ip-address
To specify the IP address and subnet mask for this system’s high availability interface, use the
interface ha ip-address command.
interface ha ip-address {A.B.C.D/bits | A.B.C.D/1.2.3.4}
Syntax Description
Defaults None.
Command Modes Administrator.
Command History
Usage Guidelines The HA features are used within a cluster of storage routers. Each member of the cluster communicates
over the HA and management interfaces, exchanging heartbeats and other configuration information,
allowing for failover in case of system problems.
The HA interface and the management interface must be on unique IP subnets. In a cluster, the HA
interfaces for all nodes should be on the same IP subnet.
After initial system configuration, use the setup cluster command to change the configuration of the
high availability environment.
For SN 5428-2 Storage Routers deployed for transparent SCSI routing, or standalone storage routers
deployed for SCSI routing, the HA interface is optional.
Examples The following example assigns the IP address of 10.1.20.56/24 to the HA interface:
[SN5428-2B]# interface ha ip-address 10.1.20.56/24
A.B.C.D/nn The IP address of the HA interface. A.B.C.D is the dotted quad notation of
the IP address. The /bits specifies the subnet mask in CIDR style.
A.B.C.D/1.2.3.4 The IP address of the HA interface. A.B.C.D is the dotted quad notation of
the IP address. 1.2.3.4 is the dotted quad notation of the subnet mask.
