Use 'cio_ignore -l' to display the ranges of ignored devices. You need to un-ignore your devices to make them visible (try 'cio_ignore -r 0.0.0204-0.0.0206'). > > # echo 0.0.204,0.0.205,0.0.206 > /sys/bus/ccwgroup/drivers/qeth/group > -bash: echo: write error: Invalid argument You cannot group devices that don't show up in lscss. But even more importantly, the IDs always are of the format 0.m.nnnn (so you'd need to use 0.0.0204 instead of 0.0.204). Background: the IDs are not integers, but strings, so they need to match exactly. ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to lists...@vm.marist.edu with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390 ---------------------------------------------------------------------- For more information on Linux on System z, visit http://wiki.linuxvm.org/
