Handling Media Requests
Preparing the Backup Device
Preparing the Backup Device
In general, a backup device 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 or Restore 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 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.
Checking the Console
During periods you are away from the console, other messages and requests can cause
media requests to scroll off the screen. When you return to the console, some messages and
requests will no longer be in view. The system keeps track of media requests until you
answer them. Use the RECALL command to check for outstanding media requests. For
example:
:RECALL
THE FOLLOWING REPLIES ARE PENDING:
?16:04/#S37/23/LDEV# FOR "T" ON MEDIA (NUM)?
