Database Version: Oracle 10.2.0.4 node count: 2 1. Stop all processes related to oracle, including databases, asm, node application, crs. 1.1, Disabled
Basic Information
Database Version: Oracle 10.2.0.4
Number of nodes: 2
1. Stop all processes related to oracle, including databases, asm, node application, and crs.
1.1 close all processes,
Crs_stop-all
2.2 shut down the crs background process and stop the running crs background process at the operating system level. It must run on all nodes.
[Root @ rac1 bin] #/etc/init. d/init. crs stop
Shutting down Oracle Cluster Ready Services (CRS ):
Stopping resources.
Successfully stopped CRS resources
Stopping CSSD.
Shutting down CSS daemon.
Shutdown request successfully issued.
Shutdown has begun. The daemons shoshould exit soon.
[Root @ rac2 ~] #/Etc/init. d/init. crs stop
Shutting down Oracle Cluster Ready Services (CRS ):
Stopping resources.
Successfully stopped CRS resources
Stopping CSSD.
Shutting down CSS daemon.
Shutdown request successfully issued.
Shutdown has begun. The daemons shoshould exit soon.
1.3 check whether all processes are disabled
[Root @ rac2 ~] # Crs_stat-t
Ii. Modify the IP settings of the Operating System
2.1 modify the/etc/hosts file (all nodes)
[Root @ rac1 ~] # Vim/etc/hosts
127.0.0.1 rac1 localhost. localdomain localhost
172.20.225.91 rac1
172.20.225.92 rac2
10.73.5.91 rac1-priv
10.73.5.92 rac2-priv
172.20.225.81 rac1-vip
172.20.225.82 rac2-vip
[Root @ rac2 ~] # Vim/etc/hosts
127.0.0.1 rac2 localhost. localdomain localhost
172.20.225.91 rac1
172.20.225.92 rac2
10.73.5.91 rac1-priv
10.73.5.92 rac2-priv
172.20.225.81 rac1-vip
172.20.225.82 rac2-vip
2.2 modify the eth0 and eth1 addresses on the two nodes, and restart the nodes to make the ip address take effect.
3. Modify the storage Link
3.1 clear the previous Link (executed by two nodes)
1) stop the service
Service iscsi stop
2) Remove mounting
Iscsiadm-m node -- op delete
3) restart the service
[Root @ rac1] # service iscsi restart
Stopping iSCSI daemon:
Iscsid is stopped [OK]
Starting iSCSI daemon: [OK]
[OK]
Setting up iSCSI targets: iscsiadm: No records found!
[OK]
3.2 relink
1) Configure openfiler correctly. Please follow the document strictly and do not omit any step.
2) scan
[Root @ 100-201 ~] # Iscsiadm-m discovery-t sendtargets-p 10.73.5.80
172.100.10.100: 3260,1 iqn.2006-01.com. openfiler: LUN2
172.100.10.100: 3260,1 iqn.2006-01.com. openfiler: LUN1
3) restart the service
Service iscsi restart
4. Start crs and configure ip addresses in oracle
3.1 view services
[Root @ rac1 ~] # Crs_stat-t3.2 start crs on two nodes and close applications started with crs
[Root @ rac1 ~] #/Etc/init. d/init. crs start
Startup will be queued to init within 90 seconds.
[Root @ rac2 ~] #/Etc/init. d/init. crs start
Startup will be queued to init within 90 seconds.
3.3 Use oifcfg to modify Nic settings. oifconfig can be used to set and view Nic usage methods.
Note: If the modified CIDR block is the same, you can skip this step.

[Root @ rac2 raw] # oifcfg getif-global
Eth0 192.168.0.0 global public
Eth1 10.10.10.0 global cluster_interconnect
-- Delete the current configuration
[Root @ rac2 raw] # oifcfg delif-global eth0
[Root @ rac2 raw] # oifcfg delif-global eth1
[Root @ rac2 raw] # oifcfg getif

[Root @ rac1 ~] # Oifcfg iflist

Eth1 10.72.0.0
-- Add again

[Root @ rac2 raw] # oifcfg setif-global eth1/ 10.72.0.0: Cluster_interconnect
[Root @ rac2 raw] # oifcfg getif
Eth0 172.255.0.0 global public
Eth1 10.72.0.0 global cluster_interconnect
[Root @ rac2 raw] # oifcfg iflist
Eth0 172.255.0.0
Eth1 10.72.0.0
Note: The IP address 0 represents a network segment. Remember to modify it. When starting OCR, the following error is reported:
[CRSOCR] [4054413904] OCR context init failure. Error: PROC-44: network address and network interface operation Error [7]
