I am trying to change the group and owner of raw device-
i.e., a slice - /dev/c0t4d0s4 - which has a symbolic link;(I'll have to come back and list the symbolic link.)
Logged in as root, I cd to /dev and ls -al the contents; then I copy the symbolic link name that occurs after
/dev/c0t4d0s4 and do a chgrp, pasting in the symbolic link name. I don't get an error message; but when I check the file listing it still shows root as the group that /dev/c0t4d0s4 belongs to. This was the prescribed
procedure at an Informix site. I've tried using the device
name- /dev/c0t4d0s4 - with chgrp also.
