• Run ./cluvfy stage -pre crsinst -n srv0dbxd11,srv0dbxd12 to verify Cluster is ready.

ASM Installation Order Overview

1. Make sure you run /etc/init.d/oracleasm scandisks. (Note if you do not see ASM Disks during install do the following)
• Run crs_stop -all on node 1 to stop CRS.
• Run showcrs to verify everything is offline
• Type reboot to reboot node 1
• Wait until everything is up. 
• As Oracle user run, 'while true; do ; showcrs ; sleep 10 ; done
• Wait until everything comes online then continue.
• Run /etc/init.d/oracleasm scandisks again. 
2. Configure Listener before running dbca
• To configure listener, source +ASM1, enter path /u00/app/oracle/product/10.2.0/ASM/
• srv0dbxd11 | ORA1020 | /export/home/oracle
  > . oraenvORACLE_SID = [ORA1020] ? +ASM1ORACLE_HOME = /u00/app/oracle/product/10.2.0/ASM/
3. Set TNS Admin
• Use the command (for each node): srvctl setenv nodeapps -n node -T TNS_ADMIN=$ORACLE_HOME/network/admin/
4. Run netca and create listeners
• srv0dbxd11 | +ASM1 | /export/home/oracle
  > /u00/app/oracle/product/10.2.0/ASM/bin/netca
• Select Cluster Configuration then click Next
• Select all nodes then click Next
• Select Listener Configuration then click Next and choose defaults. Exit when completed.
• Run lsnrctl status to verify Listener Parameter file points to /u00/app/oracle/product/10.2.0/ASM/network/admin/listener.ora
• Exit ASM and run showcrs to also verify everything is online. * Should see all 3 listeners online.

How to Install ASM Instance Using DBCA 

1. Login to node1 via VNC Viewer as Oracle user
2. Set oraenv to +ASM1
• srv0dbxd11 | ORA1020 | /export/home/oracle
  > . oraenvORACLE_SID = [ORA1020] ? +ASM1
3. Run dbca to launch GUI Installer
• srv0dbxd11 | +ASM1 | /export/home/oracle
  > /u00/app/oracle/product/10.2.0/ASM/bin/dbca
4. At the ASM Welcome screen, make sure Oracle Real Application Database radio button is checked, then click Next
   
   
5. At the DBCA: Operations  screen, select Configure Automatic Storage Management radio button, then click Next.
   
6. At the DBCA: Node Selection screen, select All Nodes then click Next
   
7. At the DBCA: Create ASM Instance screen, select Create Initialization Parameter File, then enter SYS Password, then click Next, and at the DBCA screen that says an instance will be created, click OK, to continue.
   
8. This is not an error, The listener process will run from the ASM home. Click Yes to create Listeners.
   
9. At the ASM Create Disk Groups screen, click Create New to create ASM Diskgroups for DATA and Backup Disks. 
   
    
10. Create DSAN_DATA_01 first and choose External Redundancy for Mirroring. Use ORCL:X_ASM1 disks for ASM Data Disk Group. Check with Admin for ASM disk layout.
    

11. Create DSAN_BACKUP_01 first and choose External Redundancy for Mirroring. Use /dev/raw/raw10 for ASM Disk Group
    
    
12. Click Finish to Complete ASM Instance Installation.
    
13. To verifiy ASM Storage Size do the following:
• Login via putty to one of the RAC Nodes
• source +ASM1
• connect via sqlpus
• run select name,total_mb,free_mb from v$asm_diskgroup;
