OK, I'm tracking the parmfile now. The dasdfmt (dasdfmt -f /dev/dasde -b 4096) command returns "dasdfmt: error opening device /dev/dasde: Invalid argument" after I add it to the parmfile and reboot. How does one see this device without running silo? How does one add this device with silo on a working system without killing the cat?

By the way, the dynamic attach/detach support in RH 7.2 (2.4 kernel) looks great! I've been attaching and detaching dasd to running Linux systems without difficulty (a HUGE improvement, in 2.2 kernels you needed to reboot the server to recognize the devices!).
