Requirements for Windows 2008 (DataKeeper and DataKeeper Cluster Edition)

Requirements for Windows 2008 (DataKeeper and DataKeeperCluster Edition)
While installing SteelEye DataKeeper on Windows 2008, you will be prompted with a dialog box thatasks you whether the installer should make the system configuration changes described below. If
you do not allow the installer to make these changes, you will need to make them manually after
installation is complete.
lWindows Firewall (see SteelEye DataKeeper Planning and Install Guide for additionalinformation)l

The Distributed Link Tracking Client must be disabled

In addition, if your Windows 2008 servers are not in a domain, you must enable the Local Security
policy setting "Network Access: Let Everyone permissions apply to anonymous users." If theservers are in a domain, then this setting is not required.

SteelEye DataKeeper Cluster Edition Overview
SteelEye DataKeeper Cluster Edition is a highly optimized host-based replication solution which
integrates seamlessly with Windows Server 2008/2008 R2 Failover Clustering as well as Windows
Server 2003 Cluster Service. Features of Windows Server 2008/2008 R2 Failover Clustering such as
cross-subnet failover and tunable heartbeat parameters make it easier for administrators to deploy
geographically dispersed clusters. SteelEye DataKeeper provides the data replication mechanism
which extends both versions of Windows Clustering, allowing administrators to take advantage ofthese advanced features to support non-shared disk high availability configurations.
Once SteelEye DataKeeper Cluster Edition is installed, a new storage class resource type called
DataKeeper Volume is available. This new SteelEye DataKeeper Volume resource can be used inplace of the traditional Physical Disk shared storage resource to enable geographically dispersedclusters, also known as multi-site clusters.

DataKeeper for Windows Version 7.2 Release Notes

Product Requirements

Make sure you verify the following settings prior to installing and configuring SteelEye DataKeeper
Cluster Edition.
lImportant: SIOS Technology Corp. recommends that users use Domain accounts that have
local Admin privileges on all servers running DataKeeper. If you are using Local accounts, theusername and passwords must match on all servers running DataKeeper. This
recommendation is for all editions and all platforms.

l

If using SteelEye DataKeeper Cluster Edition, the Windows Failover Cluster environment
must be installed and configured prior to installing the SteelEye DataKeeper Cluster Edition
software up to the point of creating your first cluster resource. Follow Microsoft best practices
for deploying geographically dispersed clusters, including changing the quorum mode majority
node set with a file share witness.

Important: If you fail to configure the basic Windows cluster before installing DataKeeper Cluster
Edition, you will have to do a repair installation of DataKeeper Cluster Edition before you are able tocreate a DataKeeper cluster resource.

DataKeeper for Windows Version 7.2 Release Notes

Known Issues

Issue: When evaluating SteelEye DataKeeper v7.2, an error may occur if a new evaluation
license key is not used. Evaluation licenses prior to January 1, 2011 will not work on thisrelease.
Recommended Action: A new evaluation license key must be obtained. Restart the License
Key Manager and enter the new, properly formatted license key.
Issue: In a Hyper-V host cluster, if a change is attempted to a setting of a virtual machine,such as adding a new NIC or setting a VLAN ID, an error will be received.
Recommended Action: In order to make such changes, remove the virtual machine from thefailover cluster, provision a new virtual machine using Hyper-V Manager (not Failover ClusterManager) based on the existing VHD file, make the desired changes, then add the virtualmachine back into the cluster.
Issue: In Windows Failover Clustering, an MS DTC Resource fails to come online if configured
with a DataKeeper volume resource.
Log Name: System
Source: Microsoft-Windows-FailoverClustering
Date: <Date Time>
Event ID: 1146
Task Category: Resource Control Manager
Description: The cluster resource host subsystem (RHS) stopped unexpectedly. An attempt will
be made to restart it. This is usually due to a problem in a resource DLL. Please determine which
resource DLL is causing the issue and report the problem to the resource vendor.
Recommended Action: Download and install the Microsoft Hotfix described in the following
KB article: http://support.microsoft.com/kb/978476. This will allow the MS DTC resource tooperate properly with a DataKeeper volume resource.
Issue: When File Server Resource Manager features such as Quota Management and File
Screening are enabled on a DataKeeper mirrored volume, there are occasions when DataKeeper
volume locking might fail. This occurs if the volume that is being locked contains open handles.
When these features are used in a standalone configuration, with Windows Clustering or with
SteelEye LifeKeeper, DataKeeper can be prevented from switching a mirror to another system.
Recommended Action: If switchover fails due to DataKeeper's inability to lock the volume,
terminate any processes with open handles and retry the switchover operation.

Issue: Please note the following caveats associated with DataKeeper Cluster Edition support forWindows Server 2008 R2 SP1:Mixed shared/replicated storage clusters using DataKeeper Cluster Edition are not supported onWindows Server 2008 R2 systems running the recently released SP1 for Windows Server 2008
R2. The unsupported cluster configurations included two or more nodes connected to sharedstorage replicating to one or more nodes.
Recommended Action: This issue is related to new features in SP1 that are supposed to makesupporting multisite clusters easier. Multisite cluster solutions typically implement “custom”
storage resource types (such as the DataKeeper Volume resource) in lieu of Physical Diskresources. However, SP1’s new implementation of evaluating shared storage can cause conflicts
with existing DataKeeper Volume resources. As such, we are recommending that DataKeeper
Cluster Edition customers who are using a mix of shared and replicated storage NOT upgrade toWindows Server 2008 R2 SP1 at this time.

DataKeeper for Windows7Known Issues

With SP1, we currently support cluster configurations that use only replicated disks, and we areworking with Microsoft to provide a solution for DataKeeper Cluster Edition customers who want torun Windows Server 2008 R2 SP1 in a mixed shared/replicated storage environment.
Issue: When using WSFC 2008 R2 SP1, the procedure for Extending a Traditional 1x1 2-Node
WSFC Cluster to a Shared-Replicated 3-Node Cluster has changed. The WSFC mmc GUI mustnot be used for adding a node that is hosting a DataKeeper shared volume.
Recommended Action: When using WSFC 2008 R2 SP1, additional nodes with shared
DataKeeper volumes can be safely added to an existing cluster only with the WSFC Commandline tool "cluster /add /node:<standby node name>. This is very important. Please refer to thetopic Extending a Traditional 2-Node Cluster to a Shared-Replicated Configuration for more details.
