Check the permissions on the chunk files they should all be: -rw-rw---- informix informix c0t6d0se If not then as root, since they are likely owned by root, "chmod 660 /dev/rdsk/c0t6d0se" Chances are the permissions were reset when the system booted. You should create an rc script to reset the permissions on all devices that Informix uses for chunks to 660 as part of the bootup process. Art S.
