Do I need Path-Failover for my tapelib?
Hi All,
We're planning to buy a TL2000/TL4000, but are a bit fustrated, if we need the highly priced "Path-Failover License" for the configuration.
Configuration:
- 1 Dell TL2000 or TL4000 with 1 LTO6 FC or LTO7 FC drive (half height)
- 2 Dell R730 servers (running bacula as backup sw), active-backup configuration
Possible connectivity:
Version "A": P2P links to the TL2000 from each R730
Version "B": 1 FC switch, both servers and TL2000 is connected to the FC swtich
I'm a bit new to the FC world, any thought appreciated.
Goal is to have a lightly redundandt configuration; to be able to use the tapelib from any of the R730 - but only from 1 at a time; active-passise cluster
Thanks in advance!

Hello V1pr,
With the TL2000/4000 is that going to be connected to a switch or direct connected to the 2 servers? Now with the Failover License what it will do is to failover the backup to the second server if there is a failure on the HBA to the first server. Now with that being said you can still do the failover manually without the license but if you were doing a backup then you would have to re run the backup on the second server.
As for connecting your TL2000/TL4000 to your servers what you are going to want to do is to make sure that you zone both servers to your Tape drive. If you are using a switch then you would just create the new zones with the server and the TL2000/TL4000. If you are direct connecting the TL2000/TL4000 then you would configure the Zone in the HBA that you are connecting the TL2000/TL4000 to.
Please let us know if you have any other questions.
