    NAME

    dda - MMS disk archiving driver
     
    

    SYNOPSIS

    /devices/pseudo/dda@lun:bn
    

     

    DESCRIPTION

    The Media Management System (MMS) is a distributed removable media management system based on the IEEE 1244 Media Management System specification. MMS provides a uniform and consistent tape interface to client applications.

    The dda driver is a pseudo tape drive with filesystem file media. The dda driver is a minimal emulation of the st(7D) tape driver mtio(7I) interface with BSD no-rewind behavior and is used for MMS disk archiving. The dda driver should be used with a MMS MMP mount command handle. You configure DDA tapes, drives, and libraries for disk archiving using the mmsadm(1M) command. You also use mmsadm(1M) to mount and unmount dda media.  

    CONFIGURATION

    To set the number of disk archiving tape drives available for MMS disk archiving, edit the /kernel/drv/dda.conf configuration file. The default number of disk archiving tape drives is 20.

    The disk archiving tape drive devlinks are located in the /dev/dda directory.

    The DDA maximum block size is 262144 bytes and the minimum is 1 byte.
