storage failover hwassist show

Display hardware-assisted storage failover status

Availability: This command is available to cluster administrators at the admin privilege level.

Description​

The storage failover hwassist show command displays information about the hardware-assisted storage failover status on each node. By default, the command displays the following information:

  • Node name.

  • Partner node name.

  • Whether hardware-assisted failover is enabled.

  • IP address on which the local node receives hardware-assisted failover alerts.

  • Port on which the local node receives hardware-assisted failover alerts.

  • Hardware-assisted failover status.

  • If the monitor is inactive, the reason it is inactive.

  • If the monitor is inactive, the corrective action to make it active.

  • Status of keep-alive alerts on the local node.

Hardware-assisted failover establishes a notification channel from each respective node's service processor to the other (HA partner) node. If a node becomes unresponsive, its service processor notifies the HA partner of this condition, accelerating storage failover. By default, hwassist is enabled and configured automatically to use each node's node-mgmt LIF. To modify or show the hardware-assisted storage failover configuration, use the storage failover modify and storage failover show commands.

Parameters​

{ [-fields <fieldname>, ...]
If you specify the -fields <fieldname>, ... parameter, the command output also includes the specified field or fields. You can use '-fields ?' to display the fields to specify.
| [-instance ]}
If you specify the -instance parameter, the command displays detailed information about all fields.
[-node {<nodename>|local}] - Node
If you specify this parameter, the command displays information only about hwassist on the specified nodes.
[-partner-name {<nodename>|local}] - Name of the Partner Node
If you specify this parameter, the command displays information only about hwassist on nodes with the specified partner node.
[-enabled {true|false}] - Local Hardware Assist Enabled
If you specify this parameter, the command displays information only about hwassist on nodes with the specified enabled state.
[-local-status <text>] - Local Node's Hwassist Status
If you specify this parameter, the command displays information only about hwassist on nodes with the specified local status (active or inactive).
[-local-ip <text>] - IP Address on Which Local Node is Listening
If you specify this parameter, the command displays information only about hwassist on nodes with the specified local IP address.
[-local-port <integer>] - Port on Which Local Node is Listening
If you specify this parameter, the command displays information only about hwassist on nodes with the specified local UDP port.
[-local-inactive <text>] - Local Node's Hwassist Inactive Status Reason
If you specify this parameter, the command displays information only about hwassist on nodes with the specified inactive reason.
[-local-action <text>] - Corrective Action on Local Node
If you specify this parameter, the command displays information only about hwassist on nodes with the specified corrective action.

Examples​

The following example displays the hardware-assisted failover information for node cluster1-01 and its HA partner node cluster1-02:
