Chapter 15. Advanced Functions Feature

This chapter briefly describes the advanced functions available in the Advanced Functions feature,
product Option 2. This feature includes the following advanced functions:
v Hierarchical storage management (HSM)
v Media library management
v System defined name
v Tape media library status tool
v Software encryption
v High availability for I-ASPs in a BRMS Network

Hierarchical Storage Management (HSM)
Hierarchical storage management (HSM) provides an automatic way of managing and distributing data
between the different storage layers in order to meet the users' needs for accessing data while minimizing
the overall cost. The concept of HSM involves the placement of data items in such a way as to minimize
its accessibility. BRMS provides an interface to utilize this feature.
Note: The following are brief descriptions of the HSM features. To find out more information about how
to setup BRMS for HSM, refer to Hierarchical Storage Management, SC41-5351.

Through the use of BRMS migration control groups, you can select which data to move from faster,
relatively expensive DASD to slower but less costly DASD. You might also set these control groups up to
move the data in the opposite direction if it become more frequently accessed.

Through the use of BRMS archive control groups, you can define criteria to archive less frequently used
data from disk to less expensive media (tape or optical). The criteria can be based on inactivity limit, size,
or even days used per month. Once the data meets the criteria, it is then saved to tape and deleted from
the system, no longer taking up that much-needed space.
Note: Archive feature now supports Independent ASPs and Encryption. The Hierarchical Storage
Management, SC41-5351 does not document these capabilities. Restrictions and setup are similar to
BRMS's backup control groups. For more information about Independent ASPs, refer to Chapter 17,
"Backup and Recovery of Auxiliary Storage Pool Devices," on page 303, and for Encryption refer
to "Software Encryption using BRMS" on page 162.

Dynamic Retrieval
Besides having the ability to archive the data off to removable media, it is just as important to recover the
data. A user can easily recover the data using the normal BRMS recovery process; however, BRMS also
provides Dynamic Retrieval of the data. This allows the recovery action to be prompted by a simple
access of the data. For example, if a database file has been archived, but an application actually tries to
access this file, BRMS will then be asked to restore the file. After the file is restored, the application
continues on. There is no major disruption in the application other than a delay for the restore of t

I'm really trying to understand how this data migration between disk types fits in with BRMS, or BACKUP and RECOVERY media services.
