How to use single tape to backup with 3 media server.

[Zakirk_Khan]

Hi, I have one master and media server. Also i have five media server, which is also acting as a client. All this server using one tape library. on two media server we have SAP and my requirement is that my two different media server should use one tape for backup. Problem is that is one media server use tape for backup it takes the owner ship and other media server job get failed due to media not available.

You can also configure a Media Server Group for the 3 media servers:

To configure media sharing with a server group:
Expand Media and Device Management > Devices > Server Groups.
 

This topic (and unrestricted sharing) is described in NetBackup Administrator's Guide, Volume I 

Search for 'About media sharing'

Media sharing is a short term solution... Seems you need more tapes.

Only one media server can write to a tape at any point. The other media servers will have to wait (queue). 
This may cause backups to fail if the backup window closes while jobs are queued.

You could put the clients in the same policy , set mpx then it can write to the same tape at the same time but one of the two clients will have to go via the other media server ie network. I'm curious why this is a requirement.
