Fbackup/Frecover Problems

[Jon France]

Hello all,

I'm using Fbackup/Frecover on HPUX 10.20 with a Sony AIT drive. During Frecover, I get this message:

frecover(5401): Volume 1 completed.
frecover(5404): Press return when the next volume is ready on /dev/rmt/4m:
frecover(5423): incorrect volume mounted;
frecover(5424): expected volume 2, and got 1
frecover(5433): Do you wish to continue using this volume? [yes no] frecover(5427): unable to open controlling terminal


The backup resides entirely on one tape. There is no second volume to mount. I have had the drive replaced as well as the media so I don't think that this would be a read/write problem.

Here is the command that I use:
frecover -xvf /dev/rmt/3m -G

Any ideas?

Thanks,
Jon

Try frecover with SAM.

Have you been able to restore information successfully in the past using other tapes? Maybe the backup is not exectuing correctly, and that is why you have the errors. Just a thought.

Hello,

Thanks for the input. Unfortunately, this happens on ALL of my tapes. I've cleaned the drive, switched media, and replaced the drive with another drive. The kicker is, I have a DLT drive that this works fine with. I don't want to give up the speed of the AIT but now, I don't have much choice. Any suggestions?

Hi ,

Try just getting the index from the tape and maybe that will give you some idea of what's there on the tape.

Unfortunately, the AIT tape is not fully supported. While tape drives mught seem quite simple (read, write, position, etc), each technology has a number of incompatible features and this is reflected in command options and status bits. So a simple command like tar probably work OK, but fbackup is much more sophisticated for a number of reasons, not the least of which is performance and reliability. These features require low level driver and controller support.
