Preparing the Backup Device
In general, a reel-to-reel media drive cannot be shared. Only one person
at a time can use it. Often, users cannot access media drives without
your assistance because media drives may be in a restricted computer room
or you may be required to monitor media drive use.
Users only have direct access to media drives when you provide them
physical access and configure media drives so that they are automatically
assigned to users. See "Automatically Assigning Devices," later in this
chapter.
When a user (or a program) requests the use of a media drive and the
device is available, you mount the media so that the storage process can
begin. You mount the media by preparing it, loading it onto the media
drive, and placing the media drive online.
To prepare a backup device for storing or restoring files, use the backup
media from the user you are helping (or obtain it from your media
library) and mount it on the device.
When the media is ready, you see a VOLUME MOUNTED message on the console.
For example:
16:05/31/VOL (Unlabeled) mounted on LDEV#8
The VOLUME MOUNTED message indicates the logical device (LDEV) number of
the media drive. In the example above, the LDEV number is 8. Note the
LDEV number. You use it to assign the device to STORE or RESTORE when
you respond to the media request.
