Tape library hardware issue

WhatsApp Image 2017-05-08 at 23.05.02.jpeg

Dear All,

From the error message, it looks like the tape library hardware issue. The tape library used for backup for two weeks after replace the new one.  I would like to confirm if there is SCSI cable or Tape drive or library issue.  

Thanks,

Alfred

Re: Netbackup

Is this coming from syslogs or the file name HWlog... Looks to be hardware issue.. 

But would also be important to know.. if you have reconfigured everything with the new library in netbackup.. and if you saw any configuration issues even before going for backup..

Hi IT_guys If I understood correctly this robot is attached on unix media server right? If yes, take a look this article, there are many troubleshooting for Unix/ https://www.veritas.com/support/en_US/article.TECH169477 Regards, Thiago

Re: Netbackup

Where exactly is this error log coming from?

Have you checked /var/adm/messages?
SCSI errors will be logged here and give a better idea if errors are device-related or connection related.

What errors do you see in NBU?
Have you enabled logging as suggested in TN mentioned above?

Are your devices REALLY connected via SCSI? 
If so, how old is this 'new' library actually?

I have honestly not seen SCSI-attached tape drives and library in about 10 years...

Re: Netbackup

I don't do anything just the message not occured again.  Health check no error message.  I think the problem should be on hardware but we dont have budget to replace hardware or upgrade the new NBU.

Re: Netbackup

I run the robtest, run initial and other options command, it is run completed then show invalid command.  Then I open up the NBU console ,  the device montior show it down status, and manual to up the drive and run the test policy, it completed successful.    I run scan and sgscan and tpconfig -d to show the drive is up.  I replaced the whole tape library previously and two tape drives as well, and not sure if there is the same hardware problem issue.

Questions still unanswered that will help YOU determine where exactly the issue is (HBA, cable(s) or devices):

Re: Netbackup

I don't see if any error message on the SCSI, I try to remove the robot and drive on device monitor, then reconfigure the device, it able to run the robot test.
