3–Data Migration ObjectsProtectionISR654608-00 B 3-7ProtectionDMS provides data protection against some of the common user errors byenforcing the following restrictions: An array must have an attribute of either Source, Destination, orSource+Destination to participate in the migration. When you configure adata migration job, Source LUNs can be assigned only from an array withthe attribute Source (or (Source+Destination), and Destination LUNs can beassigned only from an array with the attribute Destination (orSource+Destination). Use these attributes properly to avoid errors. A user acknowledgement is required for a data migration job after the job iscompleted. This feature provides better accounting and record-keeping forthe job. The data migration log indicates when the job was completed andwhen you acknowledge the completion status of the job. After a LUN is configured as a Destination LUN for a specific data migrationjob, the LUN cannot be configured for a different job until the current job isacknowledged or removed. DMS detects the normal configuration of Windows OS partitions on the dataLUN. Before fully configuring a data migration job, DMS provides a warningif it detects valid partition tables on the destination LUN.LogsDMS manages the following two log types: Migration logs: Migration logs provide a detailed history of each datamigration job. The job history contains information such as the start and endtime of the job, source and destination LUNs and arrays, size of the job, totaltime consumed for the job, and so on. Using SANsurfer iSCSI/FC RouterManager, you can export the migration logs out of the iSR6200. You canopen this file with a spreadsheet application such as Microsoft Excel anduse it as a data migration task report. QLogic highly recommends that yousave migration logs after the data migration job is completed and clearedfrom the iSR6200. This provides a record of every data migration job andmakes it easier to differentiate between them. System logs: System logs primarily record events, errors, and configurationchanges, and can be used for troubleshooting.
