42 Adding and Removing Nodes
Configuring Shared Storage on the New Node
Using Automatic Storage Mangement (ASM)
To extend an existing RAC database to your new nodes, configure storage for
the new nodes so that the storage is the same as on the existing nodes. If you are
using ASM, ensure that the new nodes can access the ASM disks with the same
permissions as the existing nodes. This section provides the appropriate
procedure for ASM.
To configure the ASM disks:
1
Log in as
root
.
2
Open a terminal window and log in as
root
.
3
Copy the
/dell-oracle-deployment/scripts/permissions.ini
file from one
of the existing nodes to the same location on the new node.
4
Enter the following command to set the proper permissions for block devices:
/etc/rc.local
5
Open a terminal window and perform the following steps on the new node:
a
Ty p e
service oracleasm configure
.
b
Type the following inputs for all the nodes:
Default user to own the driver interface [ ]:
oracle
Default group to own the driver interface [ ]:
dba
Start Oracle ASM library driver on boot (y/n) [n]:
y
Fix permissions of Oracle ASM disks on boot (y/n) [y]:
y
c
Ensure that the new node can access the ASM disks.
d
In the terminal window, type the following and press <Enter>:
service oracleasm scandisks
6
Ensure that the ASM disks are available on the new node.
In the terminal window, type the following and press <Enter>:
service oracleasm listdisks
All available disks on the remaining nodes are listed.
For example:
ASM1
ASM2
