Hi,

Having some issues with th MSL6000 tape library.. . Now i needed to put in more tapes for the weekly jobs and ran an inventory and i get the following error and i see media as cleaning media again.

Final error: 0xe0008114 - Physical Volume Library Robot not available.
Final error category: Backup Device Errors
Completed status: Failed

There was no problem when BE2010 was running. Its very strange.

Any suggestions!

Thanks!

After you put in the tapes, did you do either scan or an inventory.  This is to update the slot information for BE.  Note that scan is only if you are using barcode labels.

You should also run the HP LT&T utility to make sure that your tape library is function correctly.  Make sure that you select the write test and that you have stopped all the BE services beforehand.

yes i tried both scan and an inventory once i put in the tapes.I am using barcode labels for the tapes.

When i go to the HP LT& T utility the drives are marked crossed. The reason is i am usinf Symantec tape drivers and not HP drivers. I was asked by Symantec Technical Support previously to use only Symantec drivers as it was the recommended.

Do i need to remove the drivers and put HP drivers?

There is something esle which came to my attention a few hours ago. The tape library has been partitioned into two. One of daily tapes and the other one for weekly and monthly tapes. When i went to the properties of each partition, there is an option to choose which drives i need to include. Both the LTO2 and the LTO4 drives were checked for both partitions. I changed them now, so that only one partition uses one tape drive. I did an inventory after this and it succeeded. I am not entirely certain that this was the reason.

Could selecting both the tape drives in both partitions cause the tape library and the inventory to fail?

Thanks!

You should be using Symantec driver for your tape drive and your library should be listed as an Unknown Medium Changer with a Microsoft driver.

When you run the HP LT&T utility, you must stop all the BE services first.  Otherwise, it will not run.

What kind of tapes are you using in your library.  LTO2 tape drive cannot write to LTO4 tapes, likewise LTO4 tape drive cannot write to LTO2 tapes.  Did you set up your barcode rules to prevent these from happening?  See my article below

Thanks pkh for the good article. I am using LTO2 and LTO4 tapes. I did not configure any barcode rules. Since the library is configured into two partitions , i saw under the properties of each partition that it was configured to use both the LTO2 and LTO4 drives. So.. the correct setting would be to configure  the partition having LTO2 tapes to use only LTO2 drive and the parition having LT04 tapes to use only LTO4 drives. Would this be the right thing to do?

Thanks!

You can do that, but you would be restricting your flexibility.

zak2011's picture

Ok. What i miss out using this option would be that the LTO4 drives wouldnt be able to read LTO2 drives.

So the recommended way be to create bar code rules. Could you guide me on how to set it up as i was not able to find it.

Thanks!

An LTO4 drive should be able to READ LTO2 tapes, but it is not able to WRITE to it.

LTO can write to tapes 1 generation back and read 2 generations back.

If this response answers your concern, please mark it as a "solution"

zak2011's picture

Can anyone explain how to set up bar code rules in BE2012. I am not able to find this option.

Thanks!

...check: Tools --> Options --> Bar Code Rules.

Also check out pg. 529 of the Admin Guide.

Just saw this alert

Library Expansion Option Violation.

This server is licensed to support 1 tape drive in robotic libraries. However, the number of tape drives currently in use exceeds the license. You must purchase additional Library Expansion Options, or disable 1 tape drive. Please refer to product documentation for more information.

 

Looks like there is some licensing issue.

CraigV's picture

zak: BE will ship with a license for 1 drive in an autoloader/library. Every subsequent drive needa a Library Expansion Option license (LEO).

Symantec's licensing department or your vendor can provide you with this.

Eg. If you have 4 drives in a library, you need 3 LEO licenses!

Thanks Craig for the update.Previously when i used BE2010  I beleive all these licenses were installed. When i called Symantec customer service and informed them about the upgrade they sent me the licenses in a zip file. I installed the licenses and activated BE2012. Now When i go to the licensing options, currently it shows Library Expansion Option as 1. So i would need to follow up with Symantec customer support on this i suppose to show it as 2.

Thanks!

...not a bad idea to follow up, as they might have forgotten something in sending you the new licenses.

Just spoke to them now..and they say that the licenses installed are okay, since it shows one license installed and one comes built in. They have referred me to speak to Technical support.

Right click at each media discovered as "cleaning tape" and uncheck the "cleaning slot" check box.

 

Run a new inventory and try again

zak2011's picture

I checked each media discovered as cleaning tape and it was already unchecked.

Thanks!

CraigV's picture

OK, so what you try now is the following:

1. Update the firmware on the library, and make sure there are no loose cables.

2. Pull out the LTO2 drive, as well as the LTO2 tapes, Restart the library and restart the BE services, and run an inventory again...see if this changes anything. If not, repeat by pulling out the LTO4 drive and LTO4 tapes...

Thanks Craig! Technical support has just spoken to me and they siad they will need to gather some logs. Will update the post as soon as i get some answer!

Thanks!

zak2011's picture

The Technical support said they couldnt find anything wrong within backup exec 2012 and have asked me to contact the HP vendor for the tape library.

Thanks!

CraigV's picture

...and the firmware has been updated to the latest version?

What do you see in HP LTT and the tape library's management page when you view the tapes (stop the BE services!)? Does it show the tapes as cleaning tapes?

I ran the HP LTT utlity and ran all the tests for th library as well as both tape drives. All of them are passed. It showed that the firmware for the LTO4 drive was outdated. So i updated the firmware and all the tests passed after that. I didnt check the tape library management page though. Will check this out also

Thanks!

zak2011's picture

The tape library management page shows me that the tapes are in the slots. It doesnt show whether they are cleaning tapes though. Just attaching an image for a better explanation.

Thanks!

If i do a scan on the slots, then the media is recognized. However, one strange thing is that the Media label and the Barcode for most of the media are different. Why does this happen? Just attaching a screenshot if it helps.

...what happens if you do a Scan instead? Does it change the tape serial #s to what they should be?

Have you shut down the library and started it up again?

When i do a scan i find the barcode and the media label are different. It changes the serial no to what they should be. I tried shutting down the library and started again and did not make a difference.When Symantec contacted me today i mentioned to them about this. They moved the media which had different Barcode and media label to retired media and deleted it. Then they did an inventory on the slot from it was removed. After this all the medias were showing correctly.  The reason why it happened is still uncertain though.

Thanks!

zak2011's picture

Had Symantec Advanced Technical support check this issue. The reason why the tapes show as cleaning media was when an inventory was run for the partition having LT04 tapes, both the tape drives ( LTO2 and LTO4) were trying to read the LTO4 tapes..and the LT04 tapes that were being read by the LT02 tapes show up as cleaning media. He said, backup jobs can be targeted to use a specific drive in a specific partition , however utlity jobs like inventory makes use of more than one drive.

Eventhough this worked in the previous version of BE2010 R3, the current LT02 drive was not there in the Symantec compatibility list.

Suggestion provided was :

1) Disable the LT02 drive when doing an inventory for LT04 tapes.

2) Replace the LT02 drive with an LTO4 tape drive ( However if i do this, i wouldnt be able to duplicate any data to the LTO2 tapes).

Is there any tape drive that can write and read LT02 tapes other than LT02 drives.

Thanks!

CraigV's picture

LTO3 is the only other drive type, but then you mix tapes in the same library again.

zak2011's picture

Okay. So using LT03 wouldnt resolve this completely.

What would be the best alternative in getting  the LT04 tapes to get read by two tape drives during an inventory and also to be able to be write and read LT02 tapes in this case?

Thanks!

pkh's picture

LTO4 tape drive can read, but CANNOT write to LTO2 tapes.

Since you are using barcode labels, there is no need to do an inventory.  You should use scan instead. It is more efficient.  I have not done an inventory since I started using barcode labels.  Both inventory and scan is for BE to identify the tapes.  For people who are not using barcode labels, the only way to identify a tape is to inventory it.  This involves reading the internal tape label using the tape drive.  For tapes with barcode labels, the internal label is the same as that of the barcode label, so a scan of the barcode lable will identify the tape just as well as an inventory.

zak2011's picture

Since i started getting issues while inventoring using BE2012, i started using scan. It works well to recognize all the media with the correct barcodes and media label. However, the problem i always faced with scan was, media that was all media shows up as scracth.  I used to face even in BE2010R3, due to which i was hesistant to use scan and always used to run an inventory for new media. Backup Exec for some strange reason  recognizes  all media as scracth everytime i do a scan.

Thanks!

zak: do you need the data on the LTO2 tapes at all? If not, then put in an LTO4 drive to replace the LTO2 drive. As things stand, replicating to LTO2 tapes will double the amount of tapes used.

Or...buy a second-hand LTO2 drive, and connect to the media server via SCSI. Buy a new LTO4 drive for the library, and replicate that way. You won't need an additional license for the LTO2 drive in this case as it is stand-alone.

SOLUTION
zak2011's picture

Thanks for the options Craig!

The only reason i would need data on the existing LTO2 tapes now, is in the even of a restore. An LTO4 drive would be able to do this when it comes to a restore , wouldnt it? If this is the case then, replacing the LTO2 drive with an LTO4 would be my best option.

 

CraigV's picture

Yes it would...LTO4 drives would read the data off the LTO2 tapes.
