Hi All,
New to the forums and need help. Running Netbackup 7.5.0.6 on an HP DL380 G8, dual 8 Core Processors with 24 GB memory. Attached is an HP MSL2024 G3 library with two Ultrium 3000 LTO 5 drives from HP as well.
Trying to perform all the tweaks and tuning, but when we try to change the SIZE_DATA_BUFFERS file to anything over 64k, we get an error:
HP Says its an issue with NetBackup. Has anyone else seen this issue?
Solved! Go to Solution.

What OS are you running 7.5 on?
There was another thread, that addressed this same behaviour. Make sure you have the latiest drivers installed. Also refer to TECH78069, It has 2 workarounds that might help as well.

Sorry forgot to include that. Running Windows Server 2008 R2. Have all latest drivers.

Can't see how it could be NetBackup fault; might be controller issue.

Attention: Newer 64-bit versions of Windows ignore the MaximumSGList parameter because the Storport driver architecture does not support this parameter. If you are using Windows Server 2003 x64, Windows 7 x64 or Windows Server 2008 (R2) x64 then only Storport drivers are supported and therefore the block size cannot be changed. It will always be the default value of 64k. All 32-bit Windows versions are using SCSIport drivers by default and with SCSIport the MaximumSGList parameter can be changed.

I LOVE how hardware vendors simply blame the backup software!!! Doesn't matter where in the world we are!
NBU is merely reporting the problem...
I agree with above posts - HBA issue.
Some years ago, one of my colleagues found the following while assisting a customer with DR testing:
