It is a physical (timing) problem on the storage.

Definition of the disk latency in a SAN environment is a very difficult task, because there are many physical and logical nodes: operating system, physical disks, RAID, one or more HBAs, one or more fibers (HBA > SAN), ports on SAN, may be fiber-switch, and so on.


This hotfix is in the form of DSRawData.dll and GetUnsyncFileBlocks.sql.

DSRawdata.dll needs to be applied to the Recovery Solution Server. DSRawData.dll is uploaded to in attachments:

2. Browse to the %Program Files%\Altiris\Recovery Solution\Server folder.

2. Download GetUnsyncFileBlocks.sql from in attachments
3. Load the stored procedure on to the SQL Query Analyzer.
4. Select the Recovery Solution Database from the drop-down list and execute the Stored Procedure.
