TAPEPOOL Record

The TAPEPOOL record defines a resource pool in CA VM:Backup. TAPEPOOL also specifies the action that CA VM:Backup takes when the resource pool is exhausted.

TAPEPOOL pool "ParmA" | "ParmB" ["ParmC"]

ParmA:

MEDIA DASD vaddr [size] [DENSITY density]

ParmB:

MEDIA media [DENSITY density]

ParmC:

ASKOPER | ASKADD | HOLD | SCRATCH

Definitions

pool

Specifies a site-defined resource pool name. If CA VM:Backup is interfaced with CA VM:Tape and the pool is not a DASDtape pool, use a maximum of 16 characters for the pool name. Otherwise, enter a maximum of eight characters for the pool name.

MEDIA DASD vaddr [size] [DENSITY density]

MEDIA DASD

Indicates a DASDtape resource pool definition.

vaddr

Indicates the address of the associated TAPEDISK minidisk where the simulated TAPE files are stored.

size

Specifies the simulated tape length in inches. The value can be any integer from 300 to 3600. The default is 2400.

DENSITY density

Specifies the simulated density of the TAPE files. Valid DASDtape values for density are 800, 1600, 6250, and 38k. The default density is 1600.

MEDIA media [DENSITY density]

MEDIA media

Indicates a non-DASDtape resource pool containing tapes of the indicated media type.

DENSITY density

Specifies the density of the indicated media.

For more information about media types and density names, see the table Tape Drives, Media, Density Names, and TMC Values Use the column "Density Name" to check for the correct density parameter. Ensure that the correct media type and density name correspond with EDRSUP ON or OFF.

Note: To determine whether to enable EDRSUP, see Enhanced Device Recognition Support.

ASKOPER | ASKADD | HOLD | SCRATCH

Specifies the action CA VM:Backup takes when the resource pool is exhausted.

ASKOPER tells CA VM:Backup to ask the tape operator to specify the volser of the next tape to use in the job. The operator must specify the new volser twice before CA VM:Backup accepts the volser as a scratch tape. The volser is not added to the resource pool file when it is used. ASKOPER is the default for all media types except for media type DASD.

ASKADD is identical to ASKOPER except that the volser is added to the resource pool file when it is used. Tapes that are obtained from the tape operator are added to the resource pool file. The tapes are added regardless of whether they are used. For example, a tape is added even if it is completely backspaced because of an error that occurred while backing up a minidisk. ASKADD is valid for all media types.

If the interface to CA VM:Tape is enabled, ASKOPER and ASKADD are ignored. In this case, when a CA VM:Tape resource pool runs out of tapes, the job is suspended. More tapes must be added through CA VM:Tape facilities.

HOLD tells CA VM:Backup to suspend the job. HOLD is the default for media type DASD.

SCRATCH tells CA VM:Tape to obtain tapes for use in CA VM:Backup backup and MPC jobs from general scratch tapes that are found in the CA VM:Tape TMC. SCRATCH is applicable only when the CA VM:Tape interface is enabled.

Description

To use resource pools, define the CMS minidisk where CA VM:Backup stores resource pools. Define the minidisk by including a POOLDISK configuration record in the VMBACKUP CONFIG file (see POOLDISK Record).

To use a resource pool that contains DASDtapes, define the CMS minidisk where CA VM:Backup writes data for the DASDtapes. To define the minidisk, use the TAPEDISK configuration record (see TAPEDISK Record).

To use a superpool, include a SUPERPOOL configuration file record (see SUPERPOOL Record). If a DASDtape pool is included in a superpool, define at least one tape to this DASDtape pool. For more information, see "Managing Resource Pools" in the Administration Guide.

Note: If CA VM:Backup is interfaced with CA VM:Tape, define in CA VM:Tape the resource pools that CA VM:Backup and MPC jobs use. For more information, see the CA Mainframe VM Product Manager Product Interface Guide.

You can specify multiple TAPEPOOL records in the VMBACKUP CONFIG file. Each TAPEPOOL record must define a unique resource pool. If you define a resource pool but you do not specify parameters or options, the default is TAPEPOOL pool MEDIA REEL DENSITY 1600 ASKOPER.

Interactive Reconfiguration

You can dynamically edit the TAPEPOOL record on the Manage Resource Pools screen. The screen path is:

1. System Administrator Main Menu
2. Manage Resource Pools

Examples

• To specify a resource pool with a filename of DAILY, and cause CA VM:Backup to hold the job if there are no more available tapes in the pool, enter:

  TAPEPOOL DAILY MEDIA REEL HOLD
  

• The tapes in a resource pool with the filename DAILY that uses 1200-foot DASD tapes reside on the CA VM:Backup 196 minidisk. If new tapes are needed, they are added to the DAILY TAPEPOOL. To specify this resource pool, enter:

  TAPEPOOL DAILY MEDIA DASD 196 1200 DENSITY 1600 ASKADD
  

• To specify a resource pool that CA VM:Tape manages and that uses cartridges from general scratch tapes in the TMC, enter:

  TAPEPOOL VMBCART MEDIA CART DENSITY 38K SCRATCH
  

• Using EDRSUP with an STK9840 in 3590 emulation mode, specify the following resource pool by entering:

  TAPEPOOL STKVMB MEDIA STK1 DENSITY 1R35
