SC26-4920, Base Configuration: Defines systems and system groups in an SMS complex and:
Default management class
Default device geometry
Cache sets and CF cache structures used for RLS
SC26-4920, Data Class: Supplies standardized allocation defaults such as:
Record format or record organization
Primary, secondary, and directory space requirements and allocation units
Logical record length
Key length and offset
CI size, CI free percent and CA free percent
Share options
Imbed and replicate
Compaction, media type, and recording technology
Extended Format
Volume count
Data set name type (PDS, PDSE, HFS)
SC26-4920, Management Class: Used for automated space management and availability management within an SMS complex. Defines:
Number of GDG elements on primary and GDG roll off action
Data set expiration and retention criteria
Data set backup requirements
Data set migration attributes
Object class transition criteria
Aggregate backup and recovery parameters
SC26-4920, Storage Class: Defines storage and performances preferences for data sets and objects:
Response in milliseconds
CF weighting factors
Mount time in seconds
Concurrent copy
Continuous availability of critical data
Cache set name for RLS
SC26-4920, Storage Group: Groups storage so that data sets and objects can be placed by the system using attributes defined in their storage classes. The types of storage groups are:
POOL - Contains the volume serial numbers of SMS-managed DASD volumes. Pool storage groups allow groups of volumes to be managed as a single entity.
VIO - Use to allocate data sets to paging storage, which simulates the activity of a DASD volume. VIO storage groups do not contain any actual DASD volumes.
OBJECT - Describes the physical storage used objects. An object storage hierarchy consists of objects stored in DB2 table spaces on DASD, objects stored in libraries, and objects stored on shelves.
OBJECT BACKUP - Describes the physical storage used for backup copies of objects.
TAPE - Contains system-managed private tape volumes. The tape storage group definition specifies the system-managed tape libraries that can contain tape volumes.
SC26-4920, Aggregate Group: Defines groups of data sets for backup or recovery in a single operation; usually used for disaster recovery. Includes:
Expiration and retention information
Destination
Output data set name prefix
Instruction data set
Additional information for aggregate backup and recovery is defined in management class.
SC26-4920, Tape Library: Specifies the name assigned to a a collection of tape volumes and tape devices, defined in the tape configuration data base. A tape library can have the following attributes:
Status with respect to the systems in the SMS complex
Entry default use attribute, unit name, and data class
Eject default
SC26-4920, Optical Library: Specifies the name assigned to a storage device that houses optical drives and optical cartridges, as well as a mechanism for moving optical disks between a cartridge storage area and optical drives. Each optical library status with respect to the systems in the SMS complex and should be on-line to only one system.
SC26-4920, Optical Drives: Specifies the drives to be used for objects residing in optical libraries and the libraries with which each drive is associated.
