1. Login to collabn1 as oracle and open a teminal. Switch to the root user.

   

2. Install ASMLib on both nodes and initialize the disks. mount command may fail (mount: /dev/cdrom-hda already mounted or /mnt/cdrom busy) if you already have cdrom mounted from previous steps. [root@collabn1 ~]# cd /mnt [root@collabn1 mnt]# mount /mnt/cdrom mount: block device /dev/cdrom-hda is write-protected, mounting read-only [root@collabn1 mnt]# mount /mnt/cdrom5 mount: block device /dev/cdrom-hdb is write-protected, mounting read-only # OracleASM rpm -Uvh */*/oracleasm-support* rpm -Uvh */*/oracleasm*el5-2* # (Note - that's lowercase EL5-2.) # Missing from the install media; copied to RAC Attack DVD. rpm -Uvh */oracleasmlib* [root@collabn1 mnt]# /etc/init.d/oracleasm configure Configuring the Oracle ASM library driver. This will configure the on-boot properties of the Oracle ASM library driver. The following questions will determine whether the driver is loaded on boot and what permissions it will have. The current values will be shown in brackets ('[]'). Hitting <ENTER> without typing an answer will keep that current value. Ctrl-C will abort.

   [root@collabn1 ~]# /etc/init.d/oracleasm createdisk data /dev/sdb1

   Now repeat some of the steps on the second virtual machine:

   [root@collabn1 ~]# ssh collabn2
    
   [root@collabn2 ~]# cd /mnt
    
   # OracleASM
   rpm -Uvh */*/oracleasm-support*
   rpm -Uvh */*/oracleasm*el5-2*
   # Missing from the install media; copied to RAC Attack DVD.
   rpm -Uvh */oracleasmlib*
    
   [root@collabn2 ~]# /etc/init.d/oracleasm configure
   Configuring the Oracle ASM library driver.
    
   This will configure the on-boot properties of the Oracle ASM library
   driver.  The following questions will determine whether the driver is
   loaded on boot and what permissions it will have.  The current values
   will be shown in brackets ('[]').  Hitting <ENTER> without typing an
   answer will keep that current value.  Ctrl-C will abort.
