As a matter of fact, I had to do this last Friday to restore a Windows TSM
server.
I did exactly as described below in the support item Lloyd posted.

You edit a copy of your devconfig file as below.
Then when you run dsmserv restore db, the first thing you get is a MOUNT
message.
Put your 3494 in PAUSE, open the door, throw the tape in the drive requested
in the MOUNT message.

After the restore is done, remember to take the tape OUT of the drive.
Put back your original devconfig file and restart the server.

It was much less painful than I expected!

Steve,

Attached (at the end) is a snippet from a howto on IBM's support site that
you may want to look over...

Problem
One may need to temporarily configure your 3494 library as manual in order
to perform a database restore. The following provides instruction on how
to change your devconfig file to do so.

Solution
First, make a copy of your devconfig.out file and rename it. Do this so
that after the DB restore completes you can just rename the file back to
devconfig.out without having to re-write anything.

Next, open the current devconfig.out file in a text editor. All but four
lines will need to be moved.

Below is an example of the edited devconfig file:

/* Device Configuration */
DEFINE DEVCLASS 3494CLASS DEVTYPE=3590 LIBRARY=3494LIB
SET SERVERNAME SERVERNAME
DEFINE LIBRARY 3494LIB LIBTYPE=manual
DEFINE DRIVE 3494LIB DRIVE1 DEVICE=/dev/rmt/tsm_drive1

For TSM Version 5.1 and higher, edit as follows:

/* Device Configuration */
DEFINE DEVCLASS 3494CLASS DEVTYPE=3590 LIBRARY=3494LIB
SET SERVERNAME SERVERNAME
DEFINE LIBRARY 3494LIB LIBTYPE=manual
DEFINE DRIVE 3494LIB DRIVE1
DEFINE PATH SERVERNAME DRIVE1 SRCType=server DESTType=drive LIBR=3494LIB
DEVICE=/dev/rmt/tsm_drive1 ONLINE=YES

Save the file and issue your restore syntax. One will then be prompted to
mount the volume. After acknowledging the mount, the resore should run to
completion.

When the restore has completed, discard the edited devconfig file and
replace it with the old one. Assuming the restore was successful, the
server will start up and reference the proper devconfig file.
