You are right, The devices were hot-unplugged and then new devices were hot-plugged. But udev should take care of these events and should refresh its device-name mappings accordingly ? After a rebooted, new disks under /proc/partitions looks like cciss/c0d0p1 etc. how should i run scsi_id on these ? > > If you get this error all the time, you won't be > able to send any commands > to the device.
