PreviouslyPublishedAs 212274 Description This document describes Sun Fire[TM] 12K/15K/E20K/E25K: Changing Host Names on the System Controllers. Steps to Follow Note: Ensure you have a valid / working serial console connection before starting this procedure. Follow these steps to change the system controllers' host names. Step 1. Set failover off on the main SC. v4u-15ka-sc0-gmp02:sms-svc:1> showfailover SC Failover Status: ACTIVE C1: Up v4u-15ka-sc0-gmp02:sms-svc:2> setfailover off v4u-15ka-sc0-gmp02:sms-svc:3> showfailover SC Failover Status: DISABLED Step 2. IMPORTANT : Back up the following files in a secure location because sys-unconfig will remove them: /etc/defaultrouter /etc/defaultdomain /etc/hostname.INTERFACE(HME,QFE,etc) /etc/inet/hosts /etc/inet/netmasks /etc/net/*/hosts /etc/nodename /etc/resolv.conf /etc/.rootkey /etc/shadow /etc/vfstab /var/nis/NIS_COLD_START NOTE: If you are using LDAP you should back up these files also: /var/ldap/ldap_client_cache /var/ldap/ldap_client_file /var/ldap/ldap_client_cred /var/ldap/cachemgr.log Step 3. Run /usr/sbin/sys-unconfig. Fill in the new information during reboot. Step 4. Using the serial connection of the SC you are re-naming, run smsconfig -m to put new hostname into sms config. Step 5. Reboot the SC and restore ONLY the necessary information previously backed-up Step 6. Proceed in the same way on the Spare SC. Step 7. Re-enable the failover v4u-15ka-sc0-gmp02:sms-svc:3> showfailover SC Failover Status: DISABLED v4u-15ka-sc0-gmp02:sms-svc:2> setfailover on v4u-15ka-sc0-gmp02:sms-svc:1> showfailover SC Failover Status: ACTIVE C1: Up Product Sun Fire 15K Server Sun Fire 12K Server Sun Fire E25K Server Sun Fire E20K Server host name, system controller, sys-unconfig Previously Published As 49222 Change History Updated by the ESG Knowledge Content Team 4/2010 Attachments This solution has no attachment |
