Device paths for FC tape drives

Have you tried to configure the devices? Sometimes inquire will not show you anything, and still you can go and configure what you want.

It seems the inquire is not showing the robotic arm and the device is not showing the poath names. I have this at two installations both FC libraries with NW 7.4.1 & 7.4.2. The solution is:

1. Run lusbinfo -v, it gives you the HBA information.
2. In the lus.conf file, you need to enter the string for the HBA in continuation with the known-scsi-adapters. In my case, I entered: known-scsi-adapters="pci1000,b:126-32C" (EMC Suggested to use: known-scsi-adapters=" ,2:126-32C")
3. You can reboot the server or run lus_add_fp_devs from Networker. This would unload existing lus and search for devices on the new scsi-adapter.
4. Inquire would then show the robotics also.

For drives, delete all files from /dev/rmt/ for the drives(you may not do it but would be suggested), run devfsadm -Cv to create latest /dev/rmt/*cbn files, If you still don't see device path names in inquire, run the command ls -al *cbn in /dev/rmt folder. From the output, you could map the device path names. Check the last portion of the output.

Run jbconfig, enter device path names in the sequence in which you see them in this output. This would work.

I have done this twice and am sure it will help if you know the correct HBA string for your FC HBA.

Thank you Anuj for your help but everything that you say me it has already done unsuccessfully. Here I paste a fragment of lus.conf where you can check it:

known-scsi-adapters="fp:126-32 ";

name="lus" class="scsi" target=0 lun=0;
name="lus" parent="fp" target=0 lun=0 fc-port-wwn="2101001b32255d82";
name="lus" parent="fp" target=0 lun=1 fc-port-wwn="2101001b32255d82";
name="lus" parent="fp" target=1 lun=0 fc-port-wwn="2100001b32055d82";
name="lus" parent="fp" target=1 lun=1 fc-port-wwn="2100001b32055d82";

I forgot telling you that this server is Storage Node and it don't see the robotic arm. The autochanger is a Sun VTL.

About run jbconfig I ran a Scan for Devices Wizard and NetWorker showed error no. 30xx in Messages Windows (sorry don't remember the error number). It didn't detect any tapes in this SN. In your opinion, should we run a jbconfig from command line on NetWorker Server although inquire doesn't show the tapes for this SN?

There would be nothing goog running jbconfig until inquire shows them but then inquire and lus.conf of storgae node need to be worked upon.

For me, SUN helped the exact HBA string in one case & EMC IST in the second one. In the second one, I am using EMC DL210 CDL. Check if the string you are using is the correct one.

I think the HBA string is correct because I got it by lusbinfo output or is there any way to know this string?

Thank you Anuj.

Yes, I can see the devices under /dev/rmt and operate with them. I'll try to configure those next week.

I have configured the autochanger by jbconfig and it's working fine in spite of inquire doesn't show the device path.

Thanks for you help.
