NetWorker media: (warning) /dev/rmt/c13t5d0BESTnb reading: I/O Error

[Thana]

Hi all
My system use LTO2 drive with legato version.6
System has error messages "NetWorker media: (warning) /dev/rmt/c13t5d0BESTnb reading: I/O Error" Eventif I try to clean drive. Do you have any idea for the rrot cause?

Hi,

Could be a new tape, networker checks tapes to see if there is a label on the tape, tapes with no label produce an io error.

Also check if you have the latest scsi tape patches installed.

Best regards,
Robert-Jan

Hi Thana

Did you try to backup or scan the other tape?
Clean action only the drive in dirty status.
In normal case, no need to clean if the Library request to clean the drive. (you can check in the lib's console screen!)
You should try to backup with that drive but not by NetWorker, Just using native backup (OS).
Is it successful?
If not, the drive was broken or bad-->make a call to get support!
If successful, you have to check the SCSI cable as Robert-Jan Goossens said.

Hope this helps
