Configure Tape Devices

[milanda]

Hi,

Can anyone share how to configure tape devices from the master server for media servers ?

[Marianne · Accepted solution]

1. Ensure devices are visible and usable at OS level on media servers (use 'scan' command).
2. Check that correct license keys are added to media servers:
   Enterprise Server (to allow backup of network clients) or Enterprise Client (to backup only itself)
   Library Based Tape Drive license
   If drives are shared, Shared Storage Option license
3. Verify comms between master and media servers. Run these commands on the master:
   a) nbemmcmd -listhosts -verbose
   Check output for each media server. Ensure all media servers show 'Active for disk and tape'
   b) nbemmcmd -getemmserver
   Verify that Master is listed as EMM server on all media servers
4. Run Device Config wizard on Master server.

See NBU Admin Guide I for more info.
Links to all NBU manuals can be found in 'Handy NBU links' in my signature.

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

[milanda]

Thanks Sazz.. it worked...

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

[milanda]

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

[Marianne]

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

[milanda]

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:

vmoprcmd -Q

 -startltid

      Start ltid.  This option is used by java.

  -stopltid

      Stop ltid.  This option is used by java.

You should be able to combine this with -h <media server>

By the way - '-timeout' is simply extending timeout when going out to media server to scan and config. This is why command is more successful than GUI where timeout of 300 sec cannot be extended.
No need to make it that much - this is how I was given command example and how I've been posting the command here (and everyone else copied from me...).

Thanks Van...!!
