Promise TX4302 eSATA card doesn't play with a Quantum DLT-v4 tape drive

[Kirk Strauser]

I have a FreeBSD 8 server with a Quantum DLT-v4 tape drive. I'd been
using it over USB but want to switch to eSATA for various reasons.
Here's the dmesg entry for the drive when connected via USB:

sa0 at umass-sim0 bus 0 scbus0 target 0 lun 0
sa0: <QUANTUM DLT-V4 0A00> Removable Sequential Access SCSI-2 device
sa0: 40.000MB/s transfers

Here are snippets of dmesg when connecting the drive via the new Promise
TX4302 card I just installed:

atapci0: <Promise PDC40718 SATA300 controller> port

...and then device ast0 never appears. Any idea how I can get these two
pieces of hardware to play nicely together?

Would you need to load atapicam into the kernel??

That doesn't seem to change things. I'll try again later today by
rebooting with atapicam_load="YES" in /boot/loader.conf just for giggles.

I have the promise controller, I got it to add dvd burners to the system, but it will not work with the dvd drives. The promise site says the card is atapi compliant but it did not work that way for me. I had to move hard drives to the promise and add the dvd burners to the on board esata. YMMV

Good grief. Thanks for the information.
