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:
