Basic tasks for Volume Management

Following are some of the basic tasks you perform with Volume Management: Reallocating volume usage Volume usage is not always distributed evenly between users on a given volume. A few users (or groups) may use many times more volume space than others. When volume usage is significantly unequal, and volume free space is becoming limited, you can balance volume usage by reallocating heavy users or groups to a different volume with more free space. Defining volume management (VM) migration policies Migration policies define the data to be migrated. VM migration policies specify data to be migrated from a source volume to a destination volume. These migration policies let you specify that data is migrated by saved queries, by watermark levels, or by migrating all data from the source volume. Defining hierarchical storage management (HSM) migration policies Migration policies define the data to be migrated. Hierarchical storage management (HSM) migration policies direct data to be migrated between storage tiers. Data can be migrated from a primary to a secondary tier, from a primary to a tertiary tier, or from a secondary to a tertiary tier. These migration policies let you choose whether to purge the original data after migration or to purge when specified watermark levels are reached. Data migration After defining the data to be migrated, you can migrate the data to the specified location. Migrating data involves previewing the migration results, marking the files for migrate, and then migrating the data. Generating reports After migrating data, you can generate migration reports to determine how much data was migrated between volumes or tiers, and to see which migration policies migrated the data. You can refine reports by date, by policy, or you can generate a report covering all current migration policies. Reports can be printed or saved to a file.
