It's just a warning - you can ignore it.

ishita21 · Answer

but  i am unable to configure the libraries in Networker 8.2

ble1 · Answer

What is the error?  Did you use jbconfig or GUI?

CarlosRojas · Answer

Hi Ishita, What is the error you get when trying to configure the devices? Do you have persistent binding configured? Thank you, Carlos

ishita21 · Answer

using GUI on scan for devices , getting warning as could not find nsr device resource for /nst/xx

ble1 · Answer

Using Linux and GUI is kind of contradiction :-D

You probably wish to use persistent names (check /dev/tape/by-id folder) - I believe jbconfig -p should be used. Also check if you see library (you can use inquire or changers command). I have for example:

[hcrvelin@foo by-id]$ ll

lrwxrwxrwx 1 root root 10 Apr 14 2015 scsi-3500308c0a0eaf094-nst -> ../../nst3

and I have those configured that way:

[root@foo ~]# nsrjb -V | grep control

control port: /dev/tape/by-id/scsi-1ADIC_A0C0120420_LLA

[root@foo ~]# nsrmm | grep tape

15776:nsrjb: No jukeboxes are currently usable.

ishita21 · Answer

hi, i have used the below command on linux host and got the warning

#jbconfig -p

Jbconfig is running on host xxxx (Linux 3.10.0-229.14.1.el7.x86_64),

and is using xxxxx 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.

which activity do you want to perform? [1] 2

14484:jbconfig: Scanning SCSI buses; this may take a while ...

77662:jbconfig: CDI warning: Using old-style passthrough via st driver

14485:jbconfig:

All the Jukeboxes that are connected are already configured.

No new jukeboxes are found on host xxxx.

ble1 · Answer

a) was jbconfig executed from the host which also sees the tape library? Normally you always run this from host which controls robotics

b) if jbconfig doesn't find any library and none of them is defined, it may mean library is not visible on that host. In that case it is either that lib is not visible to the system or you are on the wrong host

c) visibility of the library, using NW tools, you can check with changes and/or inquire command(s)

CDI warning: Using old-style passthrough via st driver in RHEL 7.1

ble1 · Answer

It's warning - not error in terms of failure.  From what I see, you do see drives, but not robotic hand.  Is robotic hand zoned to this box where you run jbconfig?

ishita21 · Answer

i have zoned drives and media changer,  iam working with VTL library...

Nitesh_Turkar · Answer

Hi Ishita,

Select option no. 4 in jbconfig and try to configure the library with manual option.

It may help with the configuration.

Also check number of changers you can find on the server and the same on Networker end.

Check the changers command. (changers -l).

share the same output with us and no of Libraries on figured on NMC with name.

tc126 · Answer

i think your medium changer not seen by networker server. check your zoning. your inquire -s didnt show any changer.
