Roed, as you've been told several times, the media is being detected as DLT in 
your SL500 environment because you have a barcode rule (or the lack of one and 
a default set to DLT) in that environment that is telling NetBackup to do that. 
You need to add or modify a barcode rule that tells NetBackup to do the right 
thing with your barcodes. Since you haven't told us what barcodes are on your 
LTO-4 media (which will be six digits plus an L4, unless you've configured your 
library not to pass those final two digits through, and I don't recall whether 
you can configure an SL500 that way), nor what extant barcode rules you have, 
we can't be more specific than that. You should consult the appropriate system 
administrator's guide for your OS, volume 1, which you can find at 
http://seer.entsupport.symantec.com/docs/290282.htm, for details on how to 
configure barcode rules: I won't go into it here because it's a basic NetBackup 
administration skill.

If you are getting barcodes passed through to NetBackup with an L4 hanging of 
the end, then you will need a MEDIA_ID_BARCODE_CHARS setting in vm.conf, for 
more detail on which see http://seer.entsupport.symantec.com/docs/236271.htm.

Hope this helps...

Subject: Re: [Veritas-bu] LTO4 recognized as DLT



Hi All,
Thanks for the respon so far, I've tried to insert the LTO4 media to another 
NBU environment (ver 6.5.2) with L3000 library and its fine, NBU able to 
recognized as HCART media. but again when i insert it back to NBU ver 6.5.1 
with Sl500, NBU recognozed as DLT..

The idea is , I want to restore the image which backuped in Sl3000 & NBU 6.5.2 
to SL500 & NBU 6.5.1.

Thanks.
Roed

        Um... there is no such thing as HCART4. You have to decide whether 
you're
        going to define your LTO-4 drives as HCART3 (and risk getting all your 
LTO-4
        media frozen when NetBackup puts it in an LTO-3 drive) or define your 
LTO-4
        drives as HCART (and not get
         to use LTO-3 media in them). No, neither of those
        is attractive, which is why getting the new physical media types
        ("eventually"), which functions along a drive and media capability
        model rather than just generational tiering (Can a drive read this 
media? Can it
        write it if it's blank? Can it append to it at the current density 
(think
        IBM media types)? Can it encrypt to it?), but don't hold your breath.

        As for the original poster, NetBackup labeled that media as DLT because
        that's what your barcode rules told it to do. Go fix those.

        Is your LTO3 drive of type 'HCART3'?  And your LTO4 drive of type
        'HCART4'?

        Inventory is just done with barcodes.  Do you have a barcode rule so
        that your LTO4 media is brought in as type 'HCART4'? (or whatever type
        you
        have set your LTO4 drive to).

        For instance my DEFAULT rule brings in tapes as HCART3, but I have a 
rule
        for cleaning tapes that brings them in as HC3_CLN.
