2. Prepare the disk

Fdisk/dev/sdb

Fdisk/dev/sdc

Fdisk/dev/sdd

Fdisk/dev/sde

Produce

/dev/sdb1/dev/sdc1/dev/sdd1/dev/sde1

3. Initialization

/etc/init.d/oracleasm Enable

/etc/init.d/oracleasm Configure

Default user to own the driver interface [Oracle]:

Default Group to own the driver interface [Oinstall]:

Start Oracle ASM Library driver on Boot (y/n) [y]:

Fix Permissions of Oracle ASM disks on Boot (y/n) [y]:

Writing Oracle ASM Library driver configuration: [OK]

Scanning system for ASM disks: [OK]

4. Making ASM Disk

/etc/init.d/oracleasm Createdisk D1/DEV/SDB1

/etc/init.d/oracleasm Createdisk D2/DEV/SDC1

/etc/init.d/oracleasm Createdisk D3/DEV/SDD1

/etc/init.d/oracleasm Createdisk D4/dev/sde1

5. Create an ASM instance using DBCA

Depending on the DBCA prompt, you need to execute under the root user

/u01/app/oracle/product/10.2.0/db_1/bin/localconfig add

If the boot is not normal, or if the disk is not recognized, you will need

/u01/app/oracle/product/10.2.0/db_1/bin/localconfig Reset

and set the recognition position in DBCA change Disk Discovery Path, set it to

/dev/oracleasm/disks/*

Select 4 disks and make normal mode (one redundant)

That's it.

Error:

Check if SELinux is turned on if you can't identify the disk, and turn off SELinux if you turn it on

If you encounter ora-00600:internal error code when creating an ASM disk group, arguments: [Kfmnew], [2], [], [], [], [], [], []

Check to see if the ASM instance has been started, and if it starts, you need to close it and then restart the ASM instance for creation.

At this point, if you view the log/u01/app/oracle/product/10.2.0/db_1/cfgtoollogs/dbca/trace.log you will see

ASM M_breaderstarted:false.
