Manual Load and Unload

Unless operational needs require the pre-mount of a tape volume, the preferred

method of operation is detailed below.

The processing of a manual load requires the Domain Manager running on a NonStop

server. Stand-alone loads do not require a Domain Manager and should be reserved

to restore operations in emergency cases. See “Stand Alone Load tab” of the “Web

User Interface” section of this manual for more information.

To Load a Volume

Start the tape application.

user in the SUPER group.

For a labeled volume: wait until the EMS tape mount request appears in the Home

page of the Web user interface.

For an unlabeled volume: select a volume from the Volume List page and go to

step 5.

Locate the Load button associated to the pending mount request.

Click Load; the configured devices are presented for an optional manual selection of

a device.

A page showing the configured Guardian nodes and virtual devices is presented to

the user who chooses the mount point. The virtual device can be left unspecified to

enable auto-assign processing.

To Unload a Volume

1. Locate the drive in the Home page of the BackPak user interface.

Navigate to the Unload button associated to this drive.

Click Unload; the tape volume is unloaded.

Note that unload will cancel any current operation on the tape device. If a NonStop

tape application writing or reading to or from the tape device, this application will fail

with an IO error.

Refer to the user interface section for more information.

Unlabeled Tapes

Unlabeled tapes are supported by the BackPak environment. This allows the VT

Controller to support existing tape software that expects unlabeled tapes. It is, of

course, impossible to automate the mount of unlabeled virtual volumes. All loads

must be manual.
