Display the internal options for storage failover

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

Description

The storage failover internal-options show command displays the following information about the storage failover configuration:

  • Node name

  • Whether automatic giveback is enabled

  • Whether partner checking is enabled

  • Takeover detection time, in seconds

  • Whether takeover on failover is enabled

  • Whether takeover on panic is enabled

  • Whether takeover on reboot is enabled

  • Whether hardware-assisted takeover is enabled

  • IP address on which the partner node listens to the hardware-assisted takeover alerts

  • Port on which the partner node listens to the hardware-assisted takeover alerts

  • Whether takeover on short uptime is enabled (detailed view only)

  • Short uptime interval, in seconds (detailed view only)

  • Number of giveback attempts (detailed view only)

  • Giveback attempt interval, in minutes (detailed view only)

  • Whether status is propagated through SFO mailboxes (detailed view only)

  • Status read interval, in seconds (detailed view only)

  • Status write interval, in seconds (detailed view only)

  • Hardware-assisted takeover retry count (detailed view only)

  • Hardware-assisted takeover heartbeat period (detailed view only)

  • Whether operator-initiated planned takeover is optimized

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.

| [-more ] (privilege: advanced)

This parameter displays the following additional information: :

  • Node name

  • Whether takeover on short uptime is enabled

  • Short uptime interval, in seconds

  • Number of giveback attempts

  • Giveback attempt interval, in minutes

  • Whether status is propagated through SFO mailboxes

  • Status read interval, in seconds

  • Status write interval, in seconds

  • Hardware-assisted takeover retry count

  • Hardware-assisted takeover heartbeat period

| [-instance ] }

If you specify the -instance parameter, the command displays detailed information about all fields.

[-node {<nodename>|local}] - Node (privilege: advanced)

Selects configuration information for the specified node.

[-auto-giveback {true|false}] - Auto Giveback Enabled (privilege: advanced)

Selects configuration information for nodes that have the specified automatic giveback setting.

[-check-partner {true|false}] - Check Partner Enabled (privilege: advanced)

Selects configuration information for nodes that have the specified partner-checking setting.

[-detection-time <integer>] - Takeover Detection Time (secs) (privilege: advanced)

Selects configuration information for nodes that have the specified takeover detection time setting.

[-onfailure {true|false}] - Takeover on Failure Enabled (privilege: advanced)

Selects configuration information for nodes that have the specified takeover-on-failure setting.

[-onpanic {true|false}] - Takeover on Panic Enabled (privilege: advanced)

Selects configuration information for nodes that have the specified takeover-on-panic setting.

[-onshort-uptime {true|false}] - Takeover on Short Uptime Enabled (privilege: advanced)

Selects configuration information for nodes that have the specified takeover-on-short-uptime setting.

[-short-uptime <integer>] - Short Uptime (secs) (privilege: advanced)

Selects configuration information for nodes that have the specified takeover-on-short-uptime time setting.

[-attempts <integer>] - Number of Giveback Attempts (privilege: advanced)

Selects configuration information for nodes that have the specified number of giveback attempts setting.

[-attempts-time <integer>] - Giveback Attempts Minutes (privilege: advanced)

Selects configuration information for nodes that have the specified giveback attempt time setting.

[-propagate {true|false}] - Propagate Status via Mailbox (privilege: advanced)

Selects configuration information for nodes that have the specified setting for propagation of status through Storage Failover mailboxes.

[-read-interval <integer>] - Node Status Read Interval (secs) (privilege: advanced)

Selects configuration information for nodes that have the specified status read interval setting.

[-write-interval <integer>] - Node Status Write Interval (secs) (privilege: advanced)

Selects configuration information for nodes that have the specified status write interval setting.

[-onreboot {true|false}] - Takeover on Reboot Enabled (privilege: advanced)

Selects configuration information for nodes that have the specified takeover-on-reboot setting.

[-delay-seconds <integer>] - Delay Before Auto Giveback (secs) (privilege: advanced)

If this parameter is specified, the command displays information only about the node or nodes that have the specified delay for auto giveback.

[-hwassist {true|false}] - Hwassist Enabled (privilege: advanced)

Selects configuration information for nodes that have the specified hardware-assisted takeover setting.

[-hwassist-partner-ip <text>] - Partner's Hwassist IP (privilege: advanced)

Selects configuration information for nodes that have the specified partner IP setting for hardware-assisted takeovers.

[-hwassist-partner-port <integer>] - Partner's Hwassist Port (privilege: advanced)

Selects configuration information for nodes that have the specified partner port setting for hardware-assisted takeovers.

[-hwassist-health-check-interval <integer>] - Hwassist Health Check Interval (secs) (privilege: advanced)

Selects configuration information for nodes that have the specified health check interval setting for hardware-assisted takeovers

[-hwassist-retry-count <integer>] - Hwassist Retry Count (privilege: advanced)

Selects configuration information for nodes that have the specified retry count (in seconds) for hardware-assisted takeovers.

[-mode {ha|non_ha}] - HA Mode (privilege: advanced)

If this parameter is specified, the command displays information only about the node or nodes that have the specified HA mode.

[-bypass-takeover-optimization {true|false}] - Bypass Takeover Optimization Enabled (privilege: advanced)

Selects configuration information for nodes that have the specified setting for bypass takeover optimization ( _ true_ means that optimized operator-initiated planned takeover is bypassed, false means that it is enabled). Operator-initiated planned takeover is optimized when SFO aggregates are relocated serially to the partner prior to takeover. This reduces client outage.

Examples

The following example displays detailed information about the internal options for storage failover on a node named node2:
