2.7 Restore Control Workstation mksysb

There might be situations in which you have to rerun the script install_cw. For
example, perhaps you have restored a mksysb of the Control Workstation to
recover from the loss of a disk. Each node of the SP and the CWS has a
node_number entry in its ODM (CuAt). This entry gets lost when you restore the
mksysb image on the CWS. There are two different methods you can use to
recreate this entry.
1. Run install_cw. This will create the proper node_number entry for the
2. The other method is to create the entry in the ODM:
sdrd:2:once:/usr/bin/startsrc -g sdr
sp:2:wait:/etc/rc.sp > /dev/console 2>&1
hardmon:2:once:/usr/bin/startsrc -s hardmon
hr:2:once:/usr/bin/startsrc -g hr
hb:2:once:/usr/bin/startsrc -g hb >/dev/null 2>/dev/console
splogd:2:once:/usr/bin/startsrc -s splogd
hardmon 8435/tcp
sdr 5712/tcp
heartbeat 4893/udp
Control Workstation in the ODM. This script also performs other actions that
do not affect the configuration of the CWS and which do not need to be run to
recreate the entry in the ODM. For instance, the splogd and hardmon
subsystems are deleted and recreated.
a. Make sure that there is no old entry in the ODM:
# odmdelete -o CuAt -q "name=sp and attribute=node_number"
b. Copy the template file for the node_number entry to some temporary
disk space:
# cp /usr/lpp/ssp/install/config/cuat.sp /tmp/cuat.sp
c. Edit this file and replace the line containing the attribute value = " N n N "
with v a l u e = " 0 " , reflecting that the node number of the CWS is "0."
d. Insert this entry into the ODM:
# ODMDIR=/etc/objrepos odmadd /tmp/cuat.sp
e. Verify that the entry has been created, and remove the temporarily
created file:
