problem with backup exec 2010 r3 sp4 and LTO6 Media tapes

[asafno]

hi

we recently attched new backup library in our company , the library is HP MSL 4048 with media tapes LTO6

now , we use backup exec 2010 r3 sp4 but if you look at the media details it shows only 2.4 tb total

and if you look at media types of each tape (we have 4 inside the library there is no LTO6 media details

what i need to do and how to recognize LTO6 media tapes in the backup exec

thanks

Hi,

1. Take the name of your company out of the original post...not required!

2. Do a search for tapeinst.exe. Once done, open it and run the driver wizard and install the SYmantec drivers. Then go into Device Manager and make sure the robotics shows up as "Unknown medium changer".

Post back with an update.

Thanks!

2.4Tb is the uncompressed capacity of LTO6 tapes so what you are seeing is correct. The 6.25Tb that you see on the box assumes a 2.5:1 compression and this is hardly achievable in real life

hi

an update

i installed all the drivers by symantec and reboot the server

still no media types of LTO6 WHEN right click on the tapes

and the total size of each media is 2.4tb

now , i did a backup and restore and its ok and works fine

the only issue is with the media types , no media types for LTO6

another thing , i still using barcodes of LTO4 on LTO6 media tapes

thanks

...well if you use barcode rules then you're most likely going to confuse BE totally as to what is there. You use the barcode type for your tape. This is your issue...

Change the barcode type to the correct XXX123L6 version and your problem should be solved.

Thanks!

i am not using barcode rules

please explain how to change the barcode type?

thanks

...you need to pull it off and then put an LTO6 barcode on 1.

You might actually be limiting how BE detects that tape. It is quite possibly seeing those LTo6 tapes as LTo4 because of the incorrect label...

Thanks!

Don't worry about this.  You will also find that LTO5 is not present as a mediatype.  BE is able to sense the capacity of the tape and use it accordingly.  You only need mediatype if you are using barcode rules, which you are not using because you are not using barcode labels.

The OP isn't using barcode rules, but he IS using LTO4 barcodes on LTO6 tapes.

Thanks!

[asafno]

ok

i will try to replace the barcodes on the media tapes with LTO6 barcodes

ending with L6

i will get the barcodes for LTO6 next week and will update you

thanks

2.4Tb is the uncompressed capacity of LTO6 tapes so you would not see any change after you pot the correct barcode labels on your tapes. However it is still important to put the correct barcode labels because you may use barcode rules later

[asafno]

so you agree that total size of 2.4 TB is good and the right size of the LTO6 media tapes i have ?

i also use the encryption hardware which i enable in my msl 4048

i did some tests of backups and restores on encrypted tape and it works fine and good

just want to be calm with the size of my LTO6 media tapes and their recognizing by the BE

As I said many times before, 2.4Tb is the native uncompressed capacity for LTO6 tapes.
