David Cathey has information on the RWAST problem, I believe it is on his
fileserver, fileserv@montagar.com.

Generally, though, you cannot get rid of the RWAST process.  You can use 
Ehud's CLRREF program, available from vesta.sunquest.com and ftp.spc.edu
which should be able to clear the owner-PID from a device, allowing you
to use the device again.

To reset the tape drives, you could try the undocumented, unsupported
$ SET DEVICE/DIAGNOSE followed by $ SET DEVICE/noDIAGNOSE which causes a 
controller reset (at least on my system).
