| [AIX] HACMP 5.4에서 IP Address, Cluster Name, HostName 변경 |
|---|
|
작업할때 HACMP Serverce는 Down 상태로 만든다. 1. hostname 변경 (red -> usa, blue -> uk) 아래 usa, uk라고 나오는데, 작업한후에 메뉴얼을 만들었기 때문이다. 무시하고 그대로 따라하기 바란다. usa@/ > hostname usa uk@/ > hostname uk 2. hosts 파일변경 101 -> 201, 102 -> 202 이런식으로 양쪽 node에서 변경한다. usa@/ > vi /etc/hosts 127.0.0.1 loopback localhost # loopback (lo0) name/address # # Node1 : usa # 192.168.51.101 node1boot1 192.168.52.101 node1boot2 192.168.53.101 node1admin 192.168.53.111 appA5 # # Node2 : uk # 192.168.51.102 node2boot1 192.168.52.102 node2boot2 192.168.53.102 node2admin 192.168.53.112 appB5 3. chinet en0, en1 ip주소 변경 usa@/ > smitty chinet uk@/ > smitty chinet 에서 en0, en1을 detach&up 하면서 ip주소 변경하는데, 양쪽 노드에서 한다. 4. rhosts ip주소 변경 양쪽 노드에서 아래 파일 변경 usa@/usr/es/sbin/cluster/etc > vi rhosts 192.168.51.101 192.168.52.101 uk@/usr/es/sbin/cluster/etc > vi rhosts 192.168.51.101 192.168.52.101 변경후, 양쪽 노드에서 usa@/usr/es/sbin/cluster/etc > refresh -s clcomdES uk@/usr/es/sbin/cluster/etc > refresh -s clcomdES 해서 daemon 재실행 이제부터 작업은 usa(hacmp configuration 작업노드)에서만 하면 된다. 5. Add/Change/Show an HACMP Cluster - Extended Configuration에서 Add/Change/Show an HACMP Cluster Type or select values in entry fields. Press Enter AFTER making all desired changes. [Entry Fields] * Cluster Name [ha_cluster] NOTE: HACMP must be RESTARTED on all nodes in order for change to take effect 6. Change/Show a Node in the HACMP Cluster - Extended Configuration에서 에서 node 이름 변경하는데, 보통 hostname과 같게 한다. 아래 메뉴에서 New Node Name & Communication Path to Node를 변경한다. Change/Show a Node in the HACMP Cluster Type or select values in entry fields. Press Enter AFTER making all desired changes. [Entry Fields] * Node Name red New Node Name [] Communication Path to Node [192.168.51.201] + Persistent Node IP Label/Address node1admin 변경후 Discover HACMP-related Information from Configured Nodes 7.
