74 Configuring Database Storage on the Host
For example, if your ASM1 and ASM2 disk devices are /dev/emcpowerc1
and /dev/emcpowerd1 for Database and Recovery files respectively, then
the
permissions.ini file is modified as:
[asm]
asm1=/dev/emcpowerc1
asm2=/dev/emcpowerd1
To add an additional ASM disk device, ASM3, using /dev/emcpowere1 ,
add another entry to the session:
asm3=/dev/emcpowere1
4 After you set your permissions.ini file, run the permissions.py script
located under the
/dell-oracle-deployment/scripts/ folder:
./permissions.py
5 Run the following command to set the correct block device permissions:
/etc/rc.local
Configuring Disks for ASM Using the ORACLEASM Library Driver
1 Log in as root .
2 Open a terminal window and perform the following steps on all nodes:
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
3 Perform step 3 only if the RAC configuration uses a shared storage and a
Linux Device Mapper Multipath driver. Set the
ORACLEASM_SCANORDER
parameter in /etc/sysconfig/oracleasm as
follows:
ORACLEASM_SCANORDER="dm"
Reboot the system for the change to take effect.
4 On the first node , in the terminal window, type the following and press
<Enter>:
service oracleasm createdisk ASM1 /dev/emcpowerb1
service oracleasm createdisk ASM2 /dev/emcpowerc1
