Robotic library is down on server, Media Server

If scan does not show the robot (and /or) drives, you have a problem outside of NetBackup.

scan simply sends some scsi commands to the library/ drives to ask them to provide information about themselves.  Apart from a bit of formatting (to make the putput look nice) what you 'should' see in the scan command output is SENT from the hardware device.

Therefore, if it doesn't work, with there is a connectivity issue with the path to the device, or the device has a fault.

I appreciate scan is provided by Symantec, but it is not a NetBackup command - it simply sends scsi commands to the devices that are configured in the Operating System.

Hello All,

Thanks for your suggestions.

and Marianne below are the out puts, and we rebooted the Library couple of time and, as the server is prodution we are going to Reboot it today and i will update the status once it was done.

Tpconfig _L output:-

and when itried to configure the tape drives and Robot from Wizard below is the error i faced.

tpconfig -l shows that a robot is configured with no tape drives. 

Please show us the screen at the back?

We can see something saying '.... or drives removed from robot'.

Please use Device Monitor to rescan OS for devices, then run 'scan' again and show us the output. 
(Please copy the text in the output  - easier to post than a screenshot...)

Have you checked OS Event Viewer logs for device errors? 
Check System and Application logs.

PS:
Is this server running other applications as well?
Your robot control host should ideally not run any applications other than NBU. 
The reason for this recommendation is because of what you are experiencing right now:
Device errors need to be checked and fixed at OS level. Windows servers often need a reboot to fix such issues. If NBU is the only application on the server, a reboot should not be a problem.

Hi All,

Sorry for the delay, i was on Leave.

The Masrer/Media server and Tape Library was reboted still the issue was not fixed, when i excute the Robtest and scan its showing error, and when i try to delete the Storage devices and try to configure from Wizard its taking very Long time to scan the devices.

Below are the error messages.

Repeat of my question asked on 13 January:

Have you checked OS Event Viewer logs for device errors? 
Check System and Application logs.

Looking at scan output, the robot seems to be faulty. 
The robot itself does not know about any tape drives or slots:

You need to log a call with the robot vendor.

Hi Marianne,

Below are the error mesg found in Eventvwr

TLD(0) mode_sense ioctl() failed: The operation completed successfully.

More evidence that you need to log a call with your hardware vendor...
