Modify MetroCluster configuration options

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

Description

The metrocluster modify command modifies MetroCluster parameters for nodes in the MetroCluster configuration.

Parameters

{ -auto-switchover-failure-domain <MetroCluster AUSO Failure Domain> - Cluster Level AUSO Option

This parameter specifies configuration of the automatic switchover. Supported values are as follows:

  • auso-on-cluster-disaster - triggers an unplanned switchover if all nodes in a DR cluster are down.

  • auso-on-dr-group-disaster - triggers an unplanned switchover if both nodes of a DR group are down.

  • auso-disabled - automatic switchover is disabled.

The default value is auso-on-cluster-disaster . It is set to default value if metrolcuster configure command is issued.

The auto-switchover failure domain is set to auso-disabled if the metrocluster unconfigure command is issued.

This setting only affects the local cluster where the command is run.

| -node-name {<nodename>|local} - Node to Change the Option On }

This parameter is used to specify the node in the cluster for which the parameter needs to be modified.

[-automatic-switchover-onfailure <true>] - Node Level AUSO Option (privilege: advanced) }

This parameter is used to enable automatic switchover on failure on a node when it is disabled because of internal errors.Possible value for this field is true. This option is available in diag mode and should be used only when warning ems message comes. All the nodes in MCC configuration must have this option enabled (the default state) to enable automatic switchover on failure.

Examples

The following example shows the output of Metrocluster modification done on a node:

clusA::*> metrocluster modify -node-name clusA-01 -node-object-limit on
  [Job 168] Job succeeded: Modify is successful
clusA::*> metrocluster modify -node-name clusA-01 -automatic-switchover-onfailure false
        [Job 308] Job succeeded: Modify is successful
clusA::> metrocluster modify -auto-switchover-failure-domain auso-on-cluster-disaster
  [Job 308] Job succeeded: Modify is successful
