Adding Cybernetics LTO4 Library to Networker 8.2

Question

We are currently in the process of evaluating Networker 8.2 to replace our existing backup solution but have run into a bit of a snag.

I am trying to add a Cybernetics LTO 4 Tape library but can't get Networker to detect it. It sees all of the tape drives but only as a standalone tape drive and does not detect the library.

We are running Networker 8.22.0.1 Build.479 Eval - Linux on RHEL 7.1 x86_64 (latest patches)

The Tapedrives are connected via SAS on a splitter cable (1 -> 4) and the OS does see the library device:

[root@networker01 ~]# lsscsi

[11:0:10:0] tape HP Ultrium 4-SCSI U62B /dev/st2

[11:0:11:0] tape HP Ultrium 4-SCSI U62B /dev/st3

When trying to run the jbconfig command this is what I get:

[root@networker01 ~]# jbconfig

Jbconfig is running on host networker01 (Linux 3.10.0-229.el7.x86_64),

and is using networker01 as the NetWorker server.

1) Configure an AlphaStor Library.

2) Configure an Autodetected SCSI Jukebox.

3) Configure an Autodetected NDMP SCSI Jukebox.

4) Configure an SJI Jukebox.

5) Configure an STL Silo.

6) Exit.

No new jukeboxes are found on host networker01

Has anyone else come across a problem like this? what are my options for trying to get it resolved?

Can you post your inquire -cl and inquire -s outputs?

The problem is that inquire using st can't detect library at scsidev@0.8.1.  Just for test, does sjirdtag 0.8.1 works?

Davidtgnome · Answer

Did you try option 4, for shits and grins? This is the option for standard jukeboxes that it may not have specific model information on.

ble1 · Answer

That's bad as NW will use SJI (SCSI Jukebox Interface) to communicate to robotics.  I checked NW HW compatibility guide for for FS II with LTO4 and I could not see RH7.1 listed there so there might be issue there.  Actually, it goes up to release 5 and later models with LTO5 and LTO6 seem to be supported only on Windows.  (Multitask model on the other hand seems to be supported on RHEL6, but you have FlexStor II).

jconlin2010 · Answer

Nope. [root@networker01 ~]# sjirdtag 0.8.1 0.8.1: No such device

jconlin2010 · Answer

I have a feeling that's probably the problem. I'm going to try reloading the server as windows 2012 since that's on the compatibility list. Although this might be a good enough reason to push a new purchase through for something a bit more modern.

Thank you

Davidtgnome · Answer

It is absolutely terrible. But if it works then you've narrowed down the problem.

If it doesn't work then there may still be something missing between the device and the operating system. .

If it works then the hardware isn't supported with Networker any longer as the compatibility guide seems to indicate.
