Initialization Parameters › Initialization Parameter Descriptions › STORGRP0

STORGRP0

This parameter specifies the default tape storage group. With ERO (Expanded Retention Option), you can define up to nine additional tape storage groups.

Notes:

• For more information about this parameter, see STORGRP1 to STORGRP9 later in this chapter.
• DR tapes do not use storage groups. These parameters are only used for primary and duplex tapes.

You must run a standard or interim backup cycle to assign reports to tape storage groups specifying appropriate storage group subparameters.

Syntax:

STORGRP0=storage-group-name/tape-index/

maxgent-value/unit1-name,unit2-name/tvser1,tvser2

where:

storage-group-name

Not considered for STORGRP0, the default storage group.

If you define any additional storage groups (STORGRP1 to STORGRP9):

• You must assign each one a group-name of up to eight alphanumeric characters.
• The name DEFAULT is reserved for use by the SARPAC tape consolidation program, and therefore cannot be specified.

Reports are assigned to tape storage groups by the ERO table statement STORGRP=storage-group-name.

tape-index

Specifies an alternate naming prefix (up to 17 characters) for your backup tapes.

If this parameter is changed, tapes previously produced by CA View are still accessible. If omitted, the high-level name of the database is used.

There is no default.

maxgent-value

The maximum number of generations that can be written to one tape volume.

The minimum value is 1. The maximum value is 65535.

The default is 10.

unit1-name, unit2-name

unit1 The tape unit name allocated for backup tape archival generations

unit2 Activates tape duplexing, and specifies its tape unit name

When duplexing is activated, two tapes are mounted during the backup cycle. The first tape is for the primary backup tape, and the second tape is for the duplex tape.

The default is TAPE.

When retrieving output from tape, CA View always uses the primary backup tape. Should an error occur on the primary backup tape and a duplex exists, the product automatically attempts to recover from the error by switching to the duplex tape.

tvser1,tvser2

A range of tape volume serial numbers to be used for the backup archival generations.

The default is any scratch tape.

Volume serial numbers must be the same length, end with one or more numeric digits, and have matching beginning alphanumeric characters. Whenever a new tape is required to back up a generation, the next tape in the range is used. When the end of the range is reached, the first tape in the range is used.

Two different tape storage groups can specify the exact same range of tapes, or completely distinct ranges, but no partial overlap is allowed between groups.
