We are not starting up with -dev and yet we still get a default device generated. And we don't have any $INFORMIXDIR/ism/devices. Can you try this on your system: ism_shutdown ism_startup Whenever I do that we get a device created. And that device is giving us problems with restarting ism. We have developed a set of scripts which use ism to backup the whole system and the logs to disk and then uses normal unix backups to copy everything to tape ( the system only has 1 tape drive!) The way we do it is to create the devices to do the onbar, do the onbar, and then remove the devices. Otherwise we end up with too many devices. However, as a cross check we check if the last run completed successfully bychecking for ism knowing about any devices. If the ism has been restarted this extra device stops the scripts from functioning. > Line 457: if [[ ! -d $INFORMIXDIR/ism/devices ]] > > this tests for the existence of the devices directory.

We aren't using -inint so it can't be that which creates the device. regards Malcolm
