Adding the cdfs Configurable File System
T o c hec k for the presence of the cdfs , en ter the follo wing:
grep cdfs /etc/conf/dfile
If the display sho ws a line with cdfs , it is presen t and active.
If the display sho ws *cdfs , the driv er is not active, and y ou will need to edit
the dfile to activ ate it.
If the display sho ws nothing, then y ou will need to add the cdfs line to the
dfile b y t yping the line cdfs at the end of the le.
If y ou are running a clustered system, y ou will also need to do the same
pro cedure to the k ernel of eac h no de to make sure that the cdfs is installed,
b efore y ou reb o ot.
Rebuilding the Kernel
If y ou ha v e c hanged the conguration of the k ernel, y ou m ust rebuild it in
order to cause HP-UX to execute the new conguration.
Caution
If y ou are in a clustered en vironmen t, do these tasks in
\Single-User State" b y executing shutdown rst.
Exit from an y net w orked connections.
If y ou ha v e added the cdfs to a cluster serv er, y ou m ust
also add it to the k ernels of all the no des b efore y ou reb o ot.
In the case of a mixed cluster, failing to do so can cause a
system panic.
The following sequence of commands, ending with reb o oting y our system (the
reboot command), will accomplish the k ernel rebuild:
cd /etc/conf
config dfile
make -f config.mk
mv /hp-ux /SYSBCKUP Save a b ackup c opy of your system
mv hp-ux / Move the op er ating system to r o ot
reboot
