Define an HSM policy to purge after migration

In this method, third-party hierarchical storage management (HSM) systems purge migrated data from the source tier immediately after migration. All HSM migration policies migrate specified lower priority files to third-party storage systems. Files stored on secondary and tertiary tiers can still be read-accessed without returning them to the source volume. Prerequisites HSM migration policies require a third-party HSM system. Procedure Open the Volume Management view. Type a name for the migration policy in the Policy Name box. If you create both VM and HSM migration policies at your site, implementing a naming convention that differentiates between the two types simplifies managing your policies from the Policies tree after the policies are created. Type a description of the migration policy in the Policy Description box. Click the Definition tab. In the Policy Type section in the upper-right corner of the pane, click HSM Policy. In the Policy Status section in the upper-right corner of the pane, click Active. In the Purge Options section, click Purge After Migrate. From the Migration Tier section, specify the migration path for the selected data. Click either Primary-Secondary, Secondary-Tertiary, or Primary-Tertiary. For example, Primary-Secondary migrates data from the primary tier to the secondary tier. (Optional) In the Additional Migration Options section, select Re-Filed Files to refile the latest version of data to the same tier from which it originated. (Optional) Select Checked Out Objects to include the files of all checked-out objects in the migration. (Optional) Select In Process Objects to include the files of all in-process objects in the migration. (Optional) Select Remote Objects to include the files of all remote objects in the migration. (Optional) Select a date from the Files Accessed Before calendar to limit migration to files accessed before the specified date. (Optional) Select a date from the Files Accessed After calendar to limit migration to files accessed after the specified date. (Optional) Type a minimum and maximum number in the File Size Range From and To boxes and select the size measurement type (bytes, KB or MB) from the list to limit migration to files within the specified size range. (Optional) Select 1 or 2 from the Reverse Migrate File Accessed More Than list. Any file in the secondary or tertiary tier accessed more than the selected number of times is selected for reverse migration. (Optional) In the MetaData Query Options section, select a workspace object type from the Saved Queries list to limit migration to files of this object type. If you selected an object type in the previous step, type information into any of the boxes to further define the saved query. After you finish defining the data to be migrated, click Create at the bottom of the pane to create the migration policy. The migration policy appears under the Policies tree. Results After one or more migration policies are defined, you can preview the results of the migration, then migrate the data.
