What am I doing wrong?
I can only get a max maximum of 2GB for Max Frag Size on my dstores and
dssu's
NB 5.1 MP4 solaris_9

Thanks, Bob.
The technote described my problem exactly......
I'm planning on migrating to a new server this summer, so I'll make
sure
I install NB5.1MP5. Upgrading to NB6.0 is too ambitious for the
summer
since major releases change outputs of many administrative commands
I use.
In the meantime, has anybody tried fooling NetBackup by creating a
non-zero-sized fragment full of 0's?
