Data Migration status and reports

Data Migrator Administration Guide for Hitachi NAS Platform

Part Number

After a data migration policy has completed a cycle, it generates a data migration report that includes details about files migrated, including available free space before and after the migration. Reports of the last five scheduled migrations are routinely saved; the rest are purged. If a schedule is deleted, so are its reports.

Migration reports can be downloaded in CSV format, then imported into a spreadsheet and processed, saved, or printed. These reports are useful when studying the system access patterns, file storage tendencies, the efficiency of rules, paths, policies and schedules. By gauging file and space usage statistics of Primary and secondary storage, Data Migrator reports can be used to refine a rule or pre-condition. The more precise and aggressive the rule, the better Data Migrator serves the storage system.

To view a list of existing reports, navigate to Home>Storage Management>Data Migration Status & Reports.
