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!
