This article will help you troubleshoot an issue when starting SQL Server on a Windows Server cluster.
Symptoms
If you are installing Microsoft SQL Server on a Windows Server cluster, the cluster validation rule associated with the installation process may fail. Additionally, you may receive the following error message:
Error: Microsoft Cluster Service (MSCS) attestation failed. The cluster was not really checked there, or there are errors or disappointments in the check report. For more information, see KB953748 or SQL Server Books Online. “
The installation log file might contain a huge message like this:
05/20/2008 05:27:18 AM Slp: evaluation rule: Cluster_VerifyForErrors
2008-05-20 05:27:18 Slp: Rule is executed on the computer: SQLNode_Name
2008-05-20 05:27:18 Slp: Rule Evaluation Complete: Failed
2008-05-20 05:27:18 Slp: Rule evaluation message: either the cluster was not validated there, or errors in the validation report are also called errors.
For example, the installation log file(Detail.txt) may refer to the folder: % ProgramFiles% Microsoft SQL Server 100 Setup Bootstrap Log 20090316_112604 .
For an incredibly successful check, the rule will have a receive entry that looks like this:
Computer name: Cluster_VerifyForErrors: successful
Reason
In various cases, the verification process may fail. If this happens, you will need to perform a manual check to ensure the hardware configuration is correct before anyone tries any of the workarounds mentioned in this article. You can use the tips mentioned in the . The links provide more information about testing clusters in Windows Server environments. This tip will help you troubleshoot additional issues that you may encounter in the future if you routinely use the workaround. way. if there are any underlying problems.
Workaround
To resolve this issue, you must resolve the script that caused the validation to fail. If you can determine that the problem that caused the validation to fail can be resolved later, youyou should use some of the command line installation options in this article to ignore the error message and see which SQL server can install the failover cluster space. If you do this, before you can reuse a particular system, you will still need to troubleshoot the underlying issues that caused the validation to fail.
At the command prompt, to change the nasty drive and folder containing the SQL Server Installer (Setup.exe). Then enter one of the following commands to fail the validation rule:
For the integrated configuration of adding a failover note, run the command on the node to be added:
Setup / SkipRules = Cluster_VerifyForErrors / Action = InstallFailoverCluster.-
For a high-level or enterprise-level installation, run the following command:
Setup / SkipRules = Cluster_VerifyForErrors / Action = CompleteFailoverCluster -
If you and your family confirm this error when your company adds a node to a detected failover installation, run the command on each add On this node:
Setup / SkipRules = Cluster_VerifyForErrors / Action = AddNode.
The SkipRules configuration parameter is not an important documented feature. You should not use this parameter now to override other rules, except for the Cluster_VerifyForErrors rule, unless otherwise specified by CSS.
SQL Server Failover Cluster Acceptance Test
When using the Verify Cluster Wizard, be sure to run the targeted test series on multiple servers that customers intend to use as nodes in a large cluster. This cluster validation process tests the underlying hardware and software itself, as well as off-line, to provide an accurate assessment of how a SQL Server failover cluster can sometimes be supported in a given configuration.

In most cases where tests fail in the cluster validation signal, Microsoft considers the addition to be unsupported. There are exceptions to this rule, as in the case of multi-site (geographically dispersed) clusters.eras that often do not share storage are more likely to fail. This fix is still supported if you believe the rest of the tests passed.
A failed type test is a recommendation for corrective action. For example, if the “List of all drives” storage test fails and subsequent storage tests fail because they may also fail, contact the storage vendor directly for troubleshooting. If the network test related to IP addresses also fails, contact your network infrastructure team.

If you try this command line installation option and the SQL Server installation fails, make sureChaos hardware configuration is valid, then contact Microsoft Customer Support Services (CSS) for further assistance.
Configuring a SQL Server failover collector instance in the chaos of a Windows Server failover that has errors in the Windows Server cluster validation report is not supported. For a given SQL Server failover cluster instance to be a near-supported scenario, the Windows Server Cluster Validation report cannot contain errors. Use CSS to ensure that the overall cluster configuration is maintained.
