Tape Fullbackup Failure
Hi Everbody;
Server: One RP7410 4 CPU server
I am trying to get fullback to my tape driver. I am sure that there is no hardware issue in my tape driever neither in my HP DSS tapes because I used to same kinds of tapes and the very same tape driver in a One 4440_8 CPU and I didn't have any problems in the fullbackup process.
When I check the tape drive in the server by ioscan -fnC tape command
axbnmrmm,sys,root # ioscan -fnC tape
Class I H/W Path Driver S/W State H/W Type Description
==========================================================================
tape 0 1/0/1/0/0/1/0.3.0 stape CLAIMED DEVICE HP C5683A
/dev/rmt/0m /dev/rmt/c2t3d0BESTn
/dev/rmt/0mb /dev/rmt/c2t3d0BESTnb
/dev/rmt/0mn /dev/rmt/c2t3d0DDS
/dev/rmt/0mnb /dev/rmt/c2t3d0DDSb
/dev/rmt/c2t3d0BEST /dev/rmt/c2t3d0DDSn
/dev/rmt/c2t3d0BESTb /dev/rmt/c2t3d0DDSnb
It looks like it is detected by ioscan command and by SAM as well but when I start the fullbackup process I get this error message;
ERROR:while moving to the Beginning of Tape
Please verify if the tape is loaded
I also ran a command to check if the tape driver is mounted or not;
axbnmrmm,sys,root # mt -f /dev/rmt/0mn status
on tape open: No such device or address
I also try to run the command for mt -f /dev/rmt/0m status, mt -f /dev/rmt/0mnb status and I got the same error message.
Question1: why I get error message like on tape open: No such device or address by the result of mt -f /dev/rmt/0mn status even though it looks like being detected by SAM and ioscan?
Question 2:I see this error when I run the script (scbackup). I would like to know what it means?
ERROR:while moving to the Beginning of Tape
Please verify if the tape is loaded
I really appreciate your help and assistance.
Thank you very much in advance.
Regards
Cagri

Re: Tape Fullbackup Failure

This is a DDS4 tape drive, relatively new and will require the latest stape driver plus the latest fbackup/frecover cumulative and mt patches for your system.
> # mt -f /dev/rmt/0mn status
on tape open: No such device or address
The tape did not respond to a status request from mt or the response was unexpected. Also, this is a fast tape drive and will need a high performance SCSI card to keep up with the drive.

Not something the HP wrote. You need to read the script, find the error message, then post the portion of the script which determined that this error has occurred. Most likely, the script saw an error from mt...rewind and created the error message.
> I also try to run the command for mt -f /dev/rmt/0m status, mt -f /dev/rmt/0mnb status and I got the same error message.
There is no difference between these device files except for handling automatic rewinds.
