reinitializing a crashed SCSI CD-ROM drive without rebooting?

[bboett@bboett.dyndns.org (Bruno Boettcher)]

Hello!

have a problem, i have a long running simulation running, and i crashed
X whilst burning a data backup...

X restarted, the machine otherwise is unharmed, but the CD-ROM drive
refuses to spit out the broken CD, looking at syslog i see lots of SCSI
errors concerning that drive...

now i need the drive, cause otherwise the HD will overflow with the data
if it isn't burned regularly...... on the otherhand, i still haven't
programmed the crashstop adn recovery functionality to my simulator...
so if i stop the machine now, 3 weeks of computation will be more or
less lost....

so is there a way to let the CD-ROM drive reinitialize hard without
stopping the machine?
the SCSI controller is an Adaptec 2940
