Additional Operational Notes

The following paragraphs provide a description of the control panel menus that apply to AEM-8

devices that are to replace a combination Disk/Tape drive combo, HP or Bering models. In this

system configuration, the primary drive is at Unit 0 and the secondary drive at Unit 1.

Select Volume - The control panel Select Volume menu allows the user to set the active volume of

the primary drive. To change the active volume, press the UP or DOWN button to display:

Select Volume

...and press ENTER. The control panel will display:

Set Volume to #

...where # is the current active volume. Pressing the UP or DOWN button changes the volume

number displayed. Press the ENTER button once the desired volume number is displayed. The

activity indictor will become active (green), indicating that the unit is busy storing the new active

volume number to non-volatile memory. Once the control panel's activity indictor turns off, the

AEM-8 is ready for host access, or it can accept additional commands.

Backup - The Backup feature performs a backup of the AEM-8's primary drive, saving the data to

the secondary drive, without the use of the host-system. Instead, the Arraid AEM-8's internal SBC

initiates and manages the data transfer.

During a backup operation, data is copied from the primary drive to the secondary drive. When an

AEM-8 is configured with the secondary drive setup as MO/Tape emulator, the secondary drive uses

a special tape format. When using this tape format, the secondary drive can contain only one backup

image. Successive backup operations overwrite any existing data on the secondary drive.

After a backup operation is complete, the control panel's activity indictor turns off, the display

returns to normal, and the AEM-8 is ready for host access, or it can accept additional commands.
