Re: IBM 3494 Library Sharing
Are all the servers connected to the library? What is the connection the TSM servers have to the library? TCP/IP or RS232? TCP/IP What is the connection the servers have to the tape drives? FC or SCSI? Migrating, some FC, most are still SCSI. Are you happy with the library sharing solution? At the moment yes. We were considering drive sharing using twin tailed SCSI until we went FC, but now are slowly realising that if/when we go SAN that we need to set up the Library Manager Server and Clients. We are not too happy about this as it appears that all our media mounts then depend upon one server being alive. If this server goes down then we get no media mounts until it's repaired. Can anyone else comment on whether this is true, or is there a backup Library Manager Server ability? Did you have to set a Library Manager Server and make the rest of the servers Library Clients? Any documents I must read? READMEs are a must. Please give an explanation of the steps that were followed to share the library. Not done SAN sharing yet. If you want to know about just SCSI and TCP/IP then mail me.

Re: IBM 3494 Library Sharing
Paul, We are not SAN sharing yet. All we have is three TSM servers using the IBM 3494. One server has three 3590 tape drives connected, a second has two, and the last just one. Sometimes the first server is not really using all tapes, that is why we want to go to a more intelligent solution. What I am looking for is a solution that allows TSM servers to mount tapes in any available drive. Is that what you have? To do library sharing is TCP/IP required? or Can we keep the RS232 connection? Thanks, Manuel J.

Re: IBM 3494 Library Sharing
What I am looking for is a solution that allows TSM servers to mount tapes in any available drive. Is that what you have? No, we just have dedicated drives per TSM server, but share the library. We want to share the drives as well, but we are moving to SAN/FC before we attempt any drive sharing. Are your TSM Servers on the same computer? In that case your solution of using a script to swap drives sounds ok. To do library sharing is TCP/IP required? or Can we keep the RS232 connection? Sorry, I don't know. If all your servers are on one computer then I would have thought it would be ok. erm, if you've got 6 drives that you can swap between TSM Servers aren't you already doing library sharing? -- GMX - Die Kommunikationsplattform im Internet. http://www.gmx.net GMX Tipp: Machen Sie Ihr Hobby zu Geld bei unserem Partner 11! http://profiseller.de/info/index.php3?ac=OM.PS.PS003K00596T0409a
Re: IBM 3494 Library Sharing
We're doin that now and getting ready to expand the library to 18 frames: currently 3 sun servers and 1 aix server talking to it. Future 12 Mainframe Lpars in addition to existing hosts Are all the servers connected to the library? All servers talk to library manager Via ethernet connections What is the connection the TSM servers have to the library? TCP/IP or RS232? TCPIP What is the connection the servers have to the tape drives? SCSI right now future FC FC or SCSI? Are you happy with the library sharing solution? It works great right now Did you have to set a Library Manager Server and make the rest of the servers Library Clients? No Any documents I must read?

The library has six 3590 E1A tape drives. As today the three servers are connected to the library via RS232 serial connection, and SCSI to the tape drives. Some scripts have been written to allocate-deallocate tape drives to the servers depending on the time of the day. I would like to here from people that have one or more 3494 library shared among TSM servers. Particularly, Are all the servers connected to the library? What is the connection the TSM servers have to the library? TCP/IP or RS232? What is the connection the servers have to the tape drives? FC or SCSI? Are you happy with the library sharing solution?
