This post is to illustrate creation of ASM DISK GROUP in 11gR2 on Solaris 10-Sparc on a standalone Installation of 11gR2 Grid Infrastructure.
Install 11gR2 GRID Infrastructure software in a separate home than you oracle RDBMS software home.
configure (or) prepare your raw devices:
I have configured 3 partition to be used in ASM DG as shown below.
- change privileges and ownership of RAW devices
bash-3.00# chmod -R 775 /dev/rdsk/c1t0d0s5
bash-3.00# chmod -R 775 /dev/rdsk/c1t0d0s6
bash-3.00# chmod -R 775 /dev/rdsk/c1t0d0s7
bash-3.00# chown -R ora11g:dba /dev/rdsk/c1t0d0s5
bash-3.00# chown -R ora11g:dba /dev/rdsk/c1t0d0s6
bash-3.00# chown -R ora11g:dba /dev/rdsk/c1t0d0s7
Here ora11g is is the owner of 11gR2 Grid Infrastructure home.
use ASMCA GUI Interface for creating ASM Disk groups:
- Set ORACLE_HOME, PATH variable to Grid Infra home location.
- Make sure proper DISPLAY variable is configured.
- run command asmca
click on "create"
Here it should discover all raw devices which was configured in previous step
Select any one of the Disk with "external" redundancy and click "OK"
Creation of Disk Group completed Successfully, now you can use this Disk group for all your oracle storage requirements.
