Description

The Test-SqlAvailabilityReplica cmdlet assesses the health of availability replicas by evaluating SQL Server policy based management (PBM) policies. You must have CONNECT, VIEW SERVER STATE, and VIEW ANY DEFINITION permissions to execute this cmdlet.

Examples

Example 1: Evaluate the health of an availability replica

PS C:\> Test-SqlAvailabilityReplica -Path "SQLSERVER:\Sql\Computer\Instance\AvailabilityGroups\MainAg\AvailabilityReplicas\MainReplica"

This command evaluates the health of the availability replica named MainReplica in the MainAg availability group and outputs a brief summary.

Example 2: Evaluate the health of all availability replicas in an availability group

PS C:\> Get-ChildItem "SQLSERVER:\Sql\Computer\Instance\AvailabilityGroups\MainAg\AvailabilityReplicas" | Test-SqlAvailabilityReplica

This command evaluates the health of all availability replicas in the availability group named MainAg and outputs a brief summary for each replica.

Example 3: Evaluate the health of an availability replica for each PBM policy

PS C:\> Test-SqlAvailabilityReplica -Path "SQLSERVER:\Sql\Computer\Instance\AvailabilityGroups\MainAg\AvailabilityReplicas\MainReplica" -ShowPolicyDetails

This command evaluates the health of the availability replica named MainReplica in the MainAg availability group and outputs the evaluation results for each PBM policy that was executed.

Example 4: Evaluate the health of an availability replica and include user-defined policies

PS C:\> Test-SqlAvailabilityReplica -Path "SQLSERVER:\Sql\Computer\Instance\AvailabilityGroups\MainAg\AvailabilityReplicas\MainReplica" -AllowUserPolicies

This command evaluates the health of the availability replica named MainReplica in the MainAg availability group. User-defined policies are included in this evaluation.

Example 5: Show all availability replicas that are in an error state

PS C:\> Get-ChildItem "SQLSERVER:\Sql\Computer\Instance\AvailabilityGroups\MainAg\AvailabilityReplicas" | Test-SqlAvailabilityReplica | Where-Object { $_.HealthState -eq "Error" }

This command shows all availability replicas with a health state of "Error" in the MainAg availability group.
