Description

The Test-SqlDatabaseReplicaState cmdlet assesses the health of an availability database on all joined 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.

Module requirements: version 21+ on PowerShell 5.1; version 22+ on PowerShell 7.x.

Examples

Example 1: Evaluate the health of an availability database

PS C:\> $Path = "SQLSERVER:\Sql\Computer\Instance\AvailabilityGroups\MainAg\DatabaseReplicaStates\MainReplica.MainDatabase"
PS C:\> Test-SqlDatabaseReplicaState -Path $Path

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

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

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

This command evaluates the health of all availability databases in the MainAg availability group and outputs a brief summary for each database.

Example 3: Evaluate the health of all availability databases in an availability group showing PBM evaluation results

PS C:\> Get-ChildItem "SQLSERVER:\Sql\Computer\Instance\AvailabilityGroups\MainAg\DatabaseReplicaStates" | Test-SqlDatabaseReplicaState -ShowPolicyDetails

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

Example 4: Evaluate the health of all availability databases in an availability group and include userdefined policies

PS C:\> Get-ChildItem "SQLSERVER:\Sql\Computer\Instance\AvailabilityGroups\MainAg\DatabaseReplicaStates" | Test-SqlDatabaseReplicaState -AllowUserPolicies

This command evaluates the health of all availability databases in the MainAg availability group. User-defined policies are included in this evaluation.

Example 5: Show all availability databases in an error health state

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

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