Adding ASM Disk to existing Diskgroup

We can add an ASM disk to existing diskgroup in two ways.

   1. GUI - Using asmca utility
   2. Command Line - Using SQL Command

GUI - Using asmca utility

Check Diskgroup and ASM disk details as follows.

Now switch to root user and create ASM disk(DATA07) as follows. Here DATA07 is the new LUN partition provisioned by storage team in the alias name as DATA07. Also I'm going to create the ASM disk in the same name(DATA07)

 Once ASM disk is created, switch to grid user and invoke asmca utility as follows.

Here enter your server IP and launch the putty session.

Command Line - Using SQL Command

Here in the below example I'm going to add a new ASM disk named DISK14 to diskgroup DATA. Let us see the steps involved.

In the below SS, we've disks upto 13.

Below are the SS shows the diskgroup details.

 

In below SS, you can see disk named DATA14. Our storage team had assigned a LUN partition in the alias name as 'DATA14'.

Now as root user, create ASM disk with the newly assigned LUN partition(DATA14) .

Now switch to grid user and assign the newly created disk(DATA14) and map the same to the diskgroup DATA.
