rmsf is the command to remove device or special files. You have to manually
do it
for example

rmsf /dev/dsk/c4t0d0 /dev/rdsk/c4t0d0

Hi Vincent,

You can remove the device file by using the H/W path of the same.

#rmsf -H

if the disk/lun is removed from the server this will autmatically remove after next reboot.
