BRMS will use the available storage from the system ASP to determine the size of media images that will be created for automatic transfer to the cloud.  The default sizing is 30 GBs but may be lower if adequate storage space is not available on Disk. Review the table below for default sizing based on disk space.

Setting the Media Size Manually

The media size can be overridden by running the following command:

CALL PGM(QBRM/Q1AOLD) PARM('VRTVOLSIZE'   '*SET    '   'nnnnnnn')

where - nnnnnnn is the media size in megabytes (MB). This value must be between 0000001 (1 megabyte (MB)) and 1000000 (1 terabyte (TB)).

Individual cloud connector resources may have different size limitations. Amazon S3 and IBM Cloud Object Storage cloud resources have a media size limitation of less than 120GB. BRMS recommends using a value of 0099000 (99 gigabytes (GB)) for these cloud resources.

Displaying the Media Size

The media size can be displayed by running the following command:

CALL PGM(QBRM/Q1AOLD) PARM('VRTVOLSIZE'   '*DISPLAY')

Resetting Media Size

The media size can be reset to the default value by running the following command:

CALL PGM(QBRM/Q1AOLD) PARM('VRTVOLSIZE'   '*REMOVE')

NOTES:

  • Smaller size tape volumes may transfer quicker to the cloud because transfers can start when a tape volume is unloaded from the virtual drive. This means when a tape volume spans, the cloud transfer of the full volume can start before the backup completes.

  • Optical volume transfers do not start until the backup completes.

  • The size may be adjusted slightly to reflect minimum or maximum size of the virtual media.

  • This will not affect the sizes of optical media when BRMS creates virtual optical media for control groups QCLDBIPLxx and QCLDBGRPxx . For these, the images will be created with *DVD4700 to enable them to be burnt to physical DVD unless the Cloud NFS Solution is enabled.
