Da is a module used to read BCV disk information, and each device (symbol link) corresponds to a DA.

Ma has two kinds, the UMA is used to control the robotic arm to grab the tape, the BMA is used to transmit data, here said the BMA, is used to receive the DA sent over the instructions to back up the data to medium (tape). The number of BMA in the backup session is the same as the number of driver. One driver corresponds to one.

In the current project, the client System,cell Manager is a backup server.

Media (medium): Tape

Driver: Tape Drive

/dev/rtape: This is hpux under the driver device path, in this path LS can also see C properties, character device, character device. In GDC, it is a c2t08to and driver.

DA: It is ok to understand as a bare device in session.

MA: It's OK to understand the driver in the session.

1) Execute the pre-script

2) Start driver MA

3) Use Uma to load the tape in the slot to driver

4) Open da read every bare device, read out size is 13.5G, this is the actual size of the backup, whether it is a thin LUN, for DP, this LUN is a physical disk, regardless of the actual data inside.

5) complete a DA.

6) Tape Head inspection is no problem.

7) Rewind Tape

8) Take the tape away from the driver.

9) Complete a MA

The last number of Da backups is the same as the number of bare disks.

The number of MA is consistent with the use of several driver. Can be a three-to-one
