NBU - Robot Inventory

[ndt]

Dear,

I find a problem when configure NBU. There are 24 tapes in my tape library (Sun StorageTek SL24) but when I do scan command, It seems that my system can not discover these tapes, slot and drive as below.

Thank you.

=====================

I can not execute some subcommand of robtest, It is always spawn "user command failed, may be timeout, scsi_pkt.us_reason = 4"

Thank you.

Something wrong with robot config.

Check device documentation. This is coming back from the robot (not NBU):

Number of Drives : 0
Number of Slots  : 0
Number of Media Access Ports: 0

The robot is also not reporting on any tape drives in the robot.

Was it working before or it is new installation? As Marianne suggested there is an issue with library, check the library console for any possible errors. You could also try rebooting the library to see if it helps. Have you recently done any zoning or configuration changes that could cause this as well.

Additionally: same robot on 2 controllers?

Maybe delete devices & re-add from scratch at OS level (Solaris presumably? 10?)

[Yasuhisa_Ishika]

scan does not show product rev(firmware version), and serial number displayed is too short.

please check /var/adm/messages if any relevant messages are recorded. also consider rebooting both SL24 and your server(shutdown the server->reboot SL24->boot the server with reconfig flag).

Dear,

Thank you for all of your suggestion. Maybe I have a mistake with connecting between server and tape library. I used two cables to connect 2 SCSI ports from server to tape. And now, I just use only one.

Thanks again.

NDT.
