If tape devices and its drivers are configured correctly on media servers, no complecated steps are needed. Just start Device Configuration Wizard on GUI.

For more detail about configuring devices and drivers on media server, please check Device Configuration Guide of your own version. Or, tell us more detail about your environment like OS version, device models, bus type(Parallel SCSI/SAS/FC/iSCSI...).

Thanks Van,

But I need to do it using command line. Is there any way ?

Make sure these are visible on the OS first. If you are using SSO make sure the zoning is done correctly between master/media/library and drives. Once done you simply run the device configuration wizard on Master server.

You could do it easily using GUI but for very big environment where it gets stuck or takes time you can use the command which does the same thing

vmoprcmd -h <media-server-name> -timeout 3600 -autoconfig  -a

Thanks Sazz.. it worked...

JFI what does "-timeout 3600" switch do..?

Also any way to start the mm services on media from master... (command line plz)

Why can you not use the GUI?
You can install Java or Windows Admin Console on your desktop.

Yes Van... but the GUI session gets hung usually and to restart the media server services would be mandatory if I configure the tape devices for Media Server... and to avoid logging into each and every media server I need to know if it can be done using CLI from the master it self.  :D

Look at options in these undocumented vmoprcmd switches:
