I have a tape drive that seems to have lost its ability to negotiate
optimal settings.

I've tried everything I can except a reboot, but that can't happen
right now as this is on a production server.  I've tried rescanning
the bus; I've tried resetting the bus; I've tried powering the
library/drive off, rescanning the bus to remove the devices, powering
the library/drive back on, and rescanning again to find the devices
again; and no matter what I do, I keep getting these 3.3 MB/s transfer
rates, 8-bit bus widths, and very degraded tape performance.  Short of
a reboot, how do I restore the initial negotiation settings from when
the server was initially powered up?

And because I feel like the question is going to be asked... I think
this happened when a coworker cycled power on the tape library.  Is
there any way to reinitialize the SCSI card and renegotiate with the
attached devices?

dmesg.boot and kernel config attached.

Thanks!
Kevin
