No, Ididn't open a case but Symantec must come to my office to do a tuning. I 
just wanted to know if someone did have the same problem .

Okay, thanks!

But, that skipped a question: have you opened a case with Symantec about the 
tuning question?

It's a legitimate feature request to have different data buffer sizes for 
different media types, especially since no small number of people will be 
living in a mixed 9940/Ultrium environment right now.

Have you opened a case with any of the relevant vendors about this? (It's not 
exactly a bug, but it is something NetBackup "should" handle.)

Whose LTO-4 drives and media are you using? (Yes, they "should" be identical, 
but...)

Hello,

You can choose HCART or HCART2.

I have a question on LTO4

Did someone work on tuning LTO4 with NetBackup.

I personnaly have a media server with LTO4 and 9940B. If I modify my 
SIZE_DATA_BUFFERS from 256K to 1024K ( for LTO4 performance purpose ), then the 
backup to the 9940B generates an error 84.

Unfortunately, we can't create on the same media server,  a SIZE_DATA_BUFFERS 
for LTO4 and another file SIZE_DATA_BUFFERS for 9940B. So to be compliant with 
the always used 9940B, I was obliged to let the SIZE_DATA_BUFFERS to 256K.

Gilles.

Greetings,

We currently have a lot of investment in LTO3 Drives and Tapes and moving 
forward with LTO4. Is there a way we can se LTO4 Media Type to be different 
than HCART3 in Netbackup?

Thanks in advance.
