Get-Cluster

  • Reference
Module:
FailoverClusters

Gets information about one or more failover clusters in a given domain.

Syntax

Get-Cluster
   [[-Name] <String>]
   [-Domain <String>]
   [<CommonParameters>]

Description

The Get-Cluster cmdlet gets information about one or more failover clusters in a given domain.

This cmdlet can obtain a variety of configuration and state information about a failover cluster, including the following items:

-- State information about whether a backup is in progress.

-- State information about whether the cluster is in a forced quorum state.

-- Cross-network settings that are especially relevant for multi-site clusters.

To set a common property for the cluster, use this cmdlet to get the cluster object and then set the appropriate property on that cluster object directly.

Examples

This example displays state and property information for the local cluster in the form of a list.

Example 2

PS C:\> Get-Cluster -Name cluster1
Name 
---- 
cluster1

This example gets information about a cluster named cluster1.

Example 3

PS C:\> Get-Cluster -Domain contoso.com
Name 
---- 
cluster1 
cluster2 
cluster3

This example gets information about each of the clusters in the contoso.com domain.

Example 4

PS C:\> Get-Cluster | ForEach-Object -Process {$_.CrossSubnetDelay = 1500}

This example sets the common property called CrossSubnetDelay for the local cluster to 1500.

Example 5

PS C:\> (Get-Cluster).DynamicQuorum = 1

This example enables the Dynamic Quorum feature for the cluster.

Example 6

PS C:\> Get-Cluster | Format-List -Property Quarantine*
QuarantineDuration  : 7200
QuarantineThreshold : 3

This example shows default values for QuarantineThreshold and QuarantineDuration for the local cluster.

-- QuarantineThreshold: This is the number of times that a node can become isolated in an hour before the cluster will be quarantined. This is set to 3 by default.

--QuarantineDuration: This setting, set to 7200 seconds or 2 hours by default, controls how long a host will remain quarantined.
