Please insert overwritible media

Hi all,

I have this problem poping up

"Please insert overwritable media into the robotic library using the import command.

Overwritable media includes scratch, blank, and recyclable media. Please note that depending on the current Media Overwrite Protection setting, imported and allocated media may be overwritable as well. Consult the online help for more information on overwritable media."

I have two LTO6 tapes in slots 1 and 2.

I have scheduled to backup 11 servers to the Robotic Library 0001 (Slot 1-4)

When I started backing up both tapes kicked in, however, one has only been utilised a little bit, tape still shows 2TB free space, the other tape is full.
BE is asking me to put in overwritable tape.

Both tapes are set to 4 weeks overwrite and 10 days append.
What would be the reason that the almost emty tape is not being appended too?

 

Regards

Is this the case - http://www.symantec.com/docs/TECH60241

OR

remember if the job was running the second tape i.e the tape it will span to should be overwritable

Sorry Gurvinder Rait, the solution you provided does not refelect my problem.

Thanks for trying.

Your problem is because the tape in slot 2 is protected until 7 Mar.  It cannot be overwritten.  Your job appends to the tape in slot 1, filled it and then it needs a second tape..  This second tape needs to be overwritable.  BE will not append to a second tape.  Since the tape in slot 2 cannot be overwritten.  BE will prompt you for an overwritable tape.

Hi pkh,

Thanks for your response.

I understend that the tape can not be overwritten.
The situation is that both tapes are brand new, no data on them. initialy they were set as scratch media
The jobs ran and somehow both tapes were used initialy.

One tape filled up and in theory the other should be appandable, what does overwrite has to do with append?
especialy if it's same job. Append does not mean overwrite, it means, please add more data to the tape that still has space in it. Atleast that's the way I understand it.

If I was to set the 2nd tape to overwrite would it not overwrite the data that it just backed up few ours ago?

regards

Hi Pkh,

Went to the properties for media sets and changed append period to Infinite, hopefully this will resolve my issue.

Saying that, the append period was set to 10 day, shouldn't BE be able to append until then?

Another question,

When media set is set to infinite append and overwrite is set to 4 weeks, what would be the outcome?
Will the job overwrite the tape?
Will the job still try to append?
Will the job append untill it's full and then try to overwrite?

Regards

When you run a job which is set to append, it will append to the first appendable tape in the targeted media set.  When this tape gets full, the job will need an overwritable tape to contiinue.  BE will only append to the first tape.  For the second and subsequent tapes, BE will need an ovewritable tape.

I don't know the history of your tapes.  From your earlier screenshot, it shows that both tapes are protected until March, so BE does not have a second tape to overwrite.  Hence the prompt for an overwritable tape.

Changing to the AP to infinite will not solve your problem.

How often are you going to overwrite the tapes?  Once you have this protection period, set the OPP accordingly so the the tapes are ovewritable BEFORE the start of the job.

It appears that there is a problem.

If I backup one of the servers day earlier say on Thursday instead of Friday, then the  Friday backup will than ignore the tape that was used on Thursday even tho the backup job was meant to run on Friday and is part of the bulk backup?

Just need to understand how it works for me to use BE more effectively, because my logic right or wrong dictates otherwise and it seems illogical to me and counter intuitive.

Thanks for all your support.

You should check

1) is your 1st job is set to overwrite or append?  If it is append, then your 2nd would may not find sufficient space on the tape to append to.

2) is your 2nd job set to overwrite or append?  If it is the former, then it will always use a new overwritable tape.  If it is the latter, check my article below on why it does not append to the first tape.

In particular, take note of the overlapping job bit.

 

I would suggest that you read the data management section of the Admin Guide which can be found in BE installation directory to clarify your doubts and also these documents

Thanks for the read.

I'm after the thought process that went behind the decision to implement this

2) The job will only append to the first tape.

A job can only append to the first tape that it writes to.  When that tape is full, it will require an over writeable tape.  It cannot append to the second or subsequent tapes. This is by design and there is no way to change this behaviour.

On a more serious note. I'm now more intrigued by this. What made them come to this conclusion?
Perhaps there is a quite a good explenation for this, I just can't figure out what it is.
