Verificando o status do seu Cluster SQL Server

Olá a todos,

O post de hoje é uma dica rápida para os profissionais que precisam trabalhar com instâncias clusterizadas do SQL Server e gostariam de saber algumas informações sobre as mesmas!

Temos o uso do SERVERPROPERTY e das DMV’s: sys.dm_io_cluster_shared_drives / sys.dm_os_cluster_nodes.

Para extrair algumas informações:

SELECT 
    SERVERPROPERTY('IsClustered') as _1_Eh_Clusterizada, 
    SERVERPROPERTY('ComputerNamePhysicalNetBIOS') as NoAtual, 
    SERVERPROPERTY('Edition') as Edicao, 
    SERVERPROPERTY('MachineName') as VirtualName, 
    SERVERPROPERTY('InstanceName') as NomeInstancia,
    SERVERPROPERTY('ServerName') as Virtual_e_InstanceNames,
    SERVERPROPERTY('ProductVersion') as Versao,
    SERVERPROPERTY('ProductLevel') as NomeVersaoSemHotfixes

 

E para extrair outras informações é bastante interessante utilizar as seguintes queries:

SELECT * FROM sys.dm_io_cluster_shared_drives

SELECT * FROM sys.dm_os_cluster_nodes

Espero que as queries sejam úteis a vocês!

Abraços,

Summary:
This white paper describes the technologies available in SQL Server 2008 that can be used as part of a high-availability strategy to protect critical data. As well as describing the technologies in detail, the white paper also discusses the various causes of downtime and data loss, and how to evaluate and balance requirements and limitations when planning a high-availability strategy involving SQL Server 2008.
This white paper is targeted at architects, IT pros, and database administrators (DBAs) tasked with implementing a high-availability strategy. It assumes the reader is familiar with Windows and SQL Server and has at least a rudimentary knowledge of database concepts such as transactions.
