Chadwick,
You dont't say about...
a) Your SIZE_DATA_BUFFERS, NET_BUFFER_SIZE or NUM_DATA_BUFFERS settings
b) Which version of Solaris you are using [+ patch level]
We use a L180 with 6 x Fibre LTO-II drives, OK, it is a Fibre library, but
with multiplexing + kernel tuning I can get these drives running reliably at
60M per sec peaking at 90M per sec.
You should be able to get 30M per sec on your L9
Let me know (a) & (b) above and I will try to help.
Kev.

Subject: [Veritas-bu] LTO2 backup speed just up to 5 MB/sec under
Netbackup 4.5
Greeting!
I have installed a Sun L8 autoloader which replaces a Sun L9 model . The L8
has been successfully installed and can operate without problem. However,
the average throughput is just up to 5 MB/sec under Netbackup 4.5.
I tried to TAR a 1.2 GB file direct to the LTO2 tape, it took about a
minute. Under Netbackup, backing up the same file take about 4 mins. 30 sec.
Any idea?
Best Regards,
Chadwick Leung
