Hey David,

in /usr/openv/netbackup/db/config

create file:

SIZE_DATA_BUFFERS

with 

262144 as the entry (no leading or trailing spaces or blank lines)

Next...if you have enough memory and your /etc/system file  has been
properly 
configured 

create

NUMBER_DATA_BUFFERS

with 

16 as the entry (same rules as above)

if that works okay, try 32 and see how that is.

Also make sure you st.conf file is properly configured for your drives.

        "STK     9840",         "STK 9840 Fast Access", "STK9840",
        "STK     9940B",         "STK 9940 Tape Drive", "CLASS_T9940B",

STK9840 =       1,0x36,0,0x1d639,2,0x00,0x42,1;
CLASS_T9940B    =       1,0x36,0,0x1d639,1,0x00,0;


Is what my client has setup in theirs.

David
