The following will change the hostname of node “k22n06” to be referenced
as new node hostname “k88n06” in domain “ppd.pok.ibm.com.”

2. Update the NIM files and configuration
a. You will need to update the /etc/niminfo file to provide the new and IP
address and hostname changes for the nim client, master, and file
references.
b. If the node is a NIM master or a bootserver, you should remove all NIM
objects from the node. This is accomplished by executing the following.
/usr/sbin/nim -o unconfig master
/usr/sbin/installp -u bos.sysmgt.nim.master
3. Update PSSP files for updates
You will need to update the following files to place the new IP address and
hostname information for node and server information.
a. Update the /etc/SDR_dest_info file using new CW and SDR IP addresses
b. Update the /etc/ssp/ files cw_name server_hostname, server_name to
reference the new boot server hostname and IP address.
c. Update the /etc/ssp/reliable_hostname file to reference the new node
client hostname and IP address.
d. Make sure that SP_NAME environment variable is updated or blank.
e. Execute a /usr/lpp/ssp/kerberos/bin/kdestroy to remove any active
kerberos ticket-granting-tickets. You may need to update the
/etc/krb.conf file to point to the correct kerberos server.
Your update should now be completed at the RS/6000 SP node. You need to
make the changes at the Control Workstation and then reboot the RS/6000 SP
nodes.
C.5 Control Workstation IP Address/Hostname Changes
The following tasks need to be executed by the admin (root) user on the Control
Workstation when changing the Ethernet IP addresses or hostname.
1. In a System Partition configuration, save the current SDR attributes by
executing an archive
/usr/lpp/ssp/bin/SDRArchive
.
You may want to backup the current /spdata filesystem in case there are
problems doing the IP Address/hostname changes.
You will need to reference the current and the new IP addresses/hostnames
along with possible changes regarding system partition names (SP_NAME).
You may want to reset the SP system back into one default system partition
prior to changing the IP address hostname in the SDR.
2. Stop all the PSSP daemons sdr, hb, hr, hardmon on the CW.
/bin/stopsrc -g sdr
/bin/stopsrc -g hb
/bin/stopsrc -g hr
/bin/stopsrc -s hardmon
