Hello there, maybe someone can help me.
I've a linux box installed with two brand new Adaptec 2940-U2W
controllers, with on each a Quantum Viking II 9.1GB U2W hard disk.
I installed an "old" version of the scsi driver, (5.1.4), and it
reported a synchronous transfer speed of 20.0 MB/sec, what was pretty
low. But yesterday, I upgraded to the 5.1.7 driver, and now I get the
synchronous transfer at 40.0 MB/sec. However, it should work at 80.0
MB/sec (otherwise, U2W is pretty expensive compared to UW, isn't it? ).
But I don't know how to change it.
You can have a look at the logs below, each Quantum drive is connected
to address 0 on host 0 and host 1.
Something seems strange: the ultra flag is not set for any of the disks.
perhaps it's the source of the problem... what can I do ?
