Problem

HotFix 9 is the latest hotfix for VERITAS Storage Replicator (tm) 2.1 SP3

Error

VERITAS Storage Replicator (tm) 2.1 Service Pack 3 with Hot fix 9 full install.

Solution

Hotfix 9 is designed to resolve the under-utilization of bandwidth throttling settings, the failure to save Read Only files stored in a Roaming Profile under Windows, and a conflict with the Dell implemented NobleNet service. It also increases the work queue counter and the comm time to live (TTL).

During light replication activity, the replication engine would only use a fraction of the available bandwidth (but only when bandwidth throttling was enabled for a pair). If there were also periods of heavy replication activity, this would lead to journal buildup on the source. The replication engine now uses as much bandwidth as possible within the constraints of the available bandwidth and the throttle setting.

During heavy replication activity with limited bandwidth, if more than 65535 work items were queued, an internal counter would wrap and some journals would never be sent to the target unless the job was restarted. The counter now can handle 4294967295 items.

On rare occasions, a sync only job would fail to stop correctly on the target though the job was marked as completed. In this case, the replica would be incomplete but the job state (and log) showed no error. The only indication was an alert on the target server that said a job failed to stop and was therefore canceled. The problem is fixed with Hot fix 9 installed and running as either a source or a target. However, if it is only running as a source (e.g. the target is Hotfix 8 or below), then the following lines need to be added to the rxservice.ini file in the %Windir% directory:

[Communications]

IdleSCKeepTime=5

This parameter specifies the number of EXTRA seconds that the RxService should keep a server comm alive after the CS Groomer thread has detected that the server comm is idle. The default value is 0 - no extra delay. Idle server comms are normally groomed every two minutes. But if a grooming sweep detects an idle server comm just after a job has completed, it will close the socket to the target and cause an old target to immediately flush whatever it was doing for the jobs using that socket.

Another issue with roaming profiles has been fixed. Sometimes files in the profile that are marked as read-only are modified when the profile is saved. In this case, Hotfix 8 and prior releases would cause the profile to fail to save correctly and the user would see an Access Denied error. This has been fixed in Hotfix 9.

When certain versions of the Adaptec CI/O Array Manager that use the NobleNet Portmapper are installed on a system, Storage Replicator will not install and run correctly. This is because the Array Manager does not install all the NobleNet files necessary for Storage Replicator to run. Introduced in Hotfix 9, the Storage Replicator installer handles this case by upgrading the Array Manager NobleNet files to the version required by Storage Replicator.

This binary is a self-extracting zip file of the CD. It paths from root to VSRSP3HF9. Download the attached binary file and extract to a disk or a network share for use in installing version 2.1 SP3 Hotfix 9 of VERITAS Storage Replicator. If this will be an upgrade from a previous version, please see the related TechNote regarding the upgrade install under the Related Documents section below or run the setup.exe in the VSRSP3HF9\vsr\service pack\ directory.

For a complete install, please run VSRSP3HF9\vsr\install\setup.exe after extracting the download.

There is more information available in the Readme.txt file located in the Storage Replicator 2.1 SP3 \vsr\install directory.

You will be required to reboot after completion of this installation.

This version is compatible with Windows 2003 server. It is recommended to upgrade to VERITAS Storage Replicator 3.0 when available for full functionality on the Windows 2003 platform.

Installation of the job agent on Windows 2003 Cluster is covered in the related TechNote 262736. See Related Documents below for a link to the document.
