3. Remove the current source master objects for sdr, hb and hr for each
system partition (SP_NAME) reference.
/usr/lpp/ssp/bin/sdr -spname <SP_NAME> rmsrc
/usr/lpp/ssp/bin/hb
-spname <SP_NAME> rmsrc
/usr/lpp/ssp/bin/hr -spname <SP_NAME> rmsrc
4. Using
mktcpip
or the
chdev
command, specify the new IP address or
hostname changes required for the Control Workstation.
If multiple system partitions exist, update the “/etc/rc.net” file to reference
the new alias addresses used for system partitions. Execute the
“/etc/rc.net” to configure the new alias addresses.
5. Manually update /etc/SDR_dest_info and /spdata/sys1/spmon/hmacls files to
the new IP address and hostname used with hardmon and SDR.
Move the system partition directories found at location
/spdata/sys1/sdr/partitions from old IP addresses to the new IP addresses
for each system partition reference.
/bin/mv <OLD IP_ADDR> <New IP_ADDR>
6. Execute the setup_authent script to create authentication services for the
new hostname being used. This step should only be executed for hostname
changes for the CW. It is not required for changes made to IP addresses, or
with RS/6000 SP node updates. Reference Step 12 in the RS/6000 SP
Installation Guide. Manually check that the authentication files /etc/krb.conf,
/etc/krb.realms, and /etc/krb-srvtab reference the new hostname.
7. You need to now create the new source master resources for the sdr, hb and
hr daemons. This may be possible by executing the
/usr/lpp/ssp/inst_root/ssp.basic.post_i script to recreate the daemons, and
then start the daemons.
8. After the sdr daemon has been properly activated on the SP system,
manually execute “SDRChangeAttrValues” for the Control Workstation.
a. Change “hostname” attribute using new hostname for “SP_ports” object.
b. Change “MACN” attribute using new hostname for “Frame” object.
c. Change “control_workstation” attribute using short hostname for “ S P ”
object.
9. You will want to remove the current Network Installation Manager (NIM)
database and configuration files on the CW. You need to execute:
/usr/sbin/nim -o unconfig master
/usr/sbin/installp -u bos.sysmgt.nim.master
10. You may want to “reboot” the control workstation now. This will establish a
clean system to reflect the IP address/hostname changes. You want to verify
that all PSSP daemons are getting activated from the “/etc/inittab.”
11. Using CMI or the
spsitenv
command, specify any hostname changes that
may be referenced for ntp, printing, and user management. Reference Step
15 in the RS/6000 SP Installation Guide. (This is optional.)
12. Update the SDR objects using commands, or by using the SMIT-based 9076
SP Configuration Management Interface (CMI). You may need to execute the
following activities from each system partition.
