When dumping several devices to a single tape under the SUN OS using the following series of commands in a dump shell script: dump 9ufd /dev/nrmt8 6250 /dev/rxy0a dump 9ufd /dev/nrmt8 6250 /dev/rxy0e dump 9ufd /dev/nrmt8 6250 /dev/rxy0g What happens if nothing has changed on /dev/rxy0e? Does dump still create a dump tape file for this device or does it just ignore the command and leave the tape alone? Gregg

(Or was it every directory that *doesn't* have subdirectories? I haven't seen this in a while, it was on a vax, but I seriously doubt that Sun has fixed it). Workaround: create a file in each filesystem before starting. Don Speck speck@vlsi.caltech.edu {amdahl,scgvaxd}!cit-vax!speck
