C.6 Execution on RS/6000 SP Nodes
The following steps will need to be executed for IP address and hostname
changes for both the Control Workstation and the RS/6000 SP nodes. These
steps will be executed on each of the RS/6000 SP nodes.
1. After the reboot has completed, and your RS/6000 SP nodes have initialized,
verify that the following have the correct IP address and hostname.
•
Updated SP Ethernet address specified for the RS/6000 SP node.
• Updated default route is correct.
•
Hostname resolution files were updated correctly (/etc/hosts).
•
The /etc/SDR_dest_info file points to the CW and SDR addresses.
•
The acct_master hostname is updated for NFS export list directory
/var/adm/acct (RS/6000 SP Accounting).
•
Files in directory /etc/ssp cw_name, server_hostname, server_name, and
reliable_hostname point to the correct IP address/hostnames.
•
The files /etc/krb.conf, /etc/krb.realms, and /etc/krb-srvtab have the
correct hostnames defined.
2. You ma y have to modify the following files on the RS/6000 SP nodes to
reflect the updated IP addresses and hostname definitions.
/etc/filesystems
/etc/ntp.conf
/etc/resolv.conf
/.rhosts
/.klogin
If any of the files are not correct, make the proper updates for the correct IP
address or hostname yourself.
3. You will want to remove the current Network Installation Manager (NIM)
database and configuration files on any PSSP 2.1 bootserver node.
/usr/sbin/nim -o unconfig master
/usr/sbin/installp -u bos.sysmgt.nim.master
You should then execute
setup_server
on the bootserver node.
4. It is best to reboot all of the RS/6000 SP nodes to reflect the IP address and
hostname changes. When the RS/6000 SP nodes initialize, your RS/6000 SP
system should be activated using the new IP addresses and hostnames.
