1 Tape error

PREDATAR Control23

The tape seems ok.
I ran tapeutil, but happens when tried to open the device.

Enter the device special file name (Example: /dev/rmt0):

Select mode (1=Read/Write, 2=Read Only, 3=Write Only, 4=Append): 2

Opening device...
Operation failed with errno 2: No such file or directory

I am using library and I see the tape using qlibv
And I can see details using q vol <vol> f=d.
The last try, I changed to readonly.

O didn't create copypools yet.

The last time read was 2 years ago. :-(
What can I do ?
The access is read only, because I changed following a suggestion. I tried w/ read write too.

Copy pools are necessary in cases like this. If the tape goes bad, then you have no way of recovering your data.

Two years the last time read.
The tape seems nice.

I changed the access to read, did a audit <vol> fix=no and the result was the same.
What can I do now ?
Answering your question:
I thought the error was in label, so I did another barcode to try checkin using barcode, and the system accepts but when try to read, the system hangs.

Using q libv I can see the tape there, but I couldn´t mount it neither read.

I am able to use the tapeutil, but I can´t open the device as show below:
Enter Selection: 1

Enter the device special file name (Example: /dev/rmt0): /dev/rmt0

Select mode (1=Read/Write, 2=Read Only, 3=Write Only, 4=Append): 2

Opening device...
Operation failed with errno 46: Device not ready

Event trying w/ 1 (Read/w)

Then I can only conclude that the tape is bad - so good-bye data. You cannot recover any information out of it if you cannot mount the tape.

Without a copy of the data (since you don't have a copy pool), forgot about the data - it is lost.

You can try to recover using third party providers like Recall - if you are in the US or Canada. Elsewhere, Google for similar providers. Will work only if your data is not encrypted.

Good luck. I will not reply any further.

We found the device: /dev/lb0, but trying:
$ ./tapeutil -f /dev/lb0 inventory
Operation not supported on device, errno 22: Invalid argument

Other options gave the same.
Thanks.

Thomaz,

It sounds like the tape did get loaded into a drive, but was not readable. I concur with moon-buddy that the data should be considered lost barring an attempt with a third party recover vendor. And even with a company like Recall there are no guarantees. My own success rate with those attempts is about 15% or so.

Better fortune in future and do research the use of copypools.
