Exadata Storage server uses the cell software to manage the disks. Like volume manager, we need to build couple of virtual layers to get the grid disks.These griddisk will be used to create the ASM disk group on the database level . In this article, we will see that how we can create/delete the celldisk, griddisk,flashcache & flashlog using the cellcli utility as well as Linux command line.As i said earlier, we can also use flash disk to create the griddisks for high write intensive databases. But in most of the cases, we will be using those flash disks for flashcache and flashlog purposes due to the storage limitation.
Exadata Storage Architecture
The below diagram will explain that how the virtual storage objects are built on exadata storage server.

If you are having the Exadata quarter rack , you need to create the same size grid disks on all the exadata storage cells. Oracle ASM will mirror across all the cell nodes for redundancy. When Database requires the additional space , its highly recommended to create the griddisk with existing griddisk size.
7.How to delete the griddisk ? Drop (delete) the specific griddisk using the below syntax
CellCLI> list griddisk DATA01_DG
DATA01_DG active
CellCLI> drop griddisk DATA01_DG
GridDisk DATA01_DG successfully dropped
CellCLI> list griddisk DATA01_DG

We need to invoke cellcli utility to manage the virtual storage objects. Is it possible manage the storage from command line ? Yes. You can manage the storage from linux command line. The below example will show that all the cellcli commands can be executed from the command line.you need to provide the command along with “cellcli -e” .

Exadata – Distributed Command-Line Utility (dcli)
Distributed command line utility(dcli) provides an option to execute the monitoring and administration commands on multiple servers simultaneously. In exadata database machine , you may need to create the griddisks on all the exadata storage cells frequently. Each time, you need to login to all the storage cells and create the griddisk manually. But dcli will make our life easier once you configured the all the storage cells on any one of the storage cell or on the database node. In this article, we will see how to configure the dcli on multiple storage cells.
It’s good to configure the dcli on the database server. So that you no need to login to exadata storage cells for each grid disk creation/drop.
1. Login to the database server or any one of the exadata storage cell. Make sure all the exadata stroage cells has been added to the /etc/hosts file.
[[email protected] ~]# cat /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost
192.168.2.50 uaexacell1
192.168.2.51 uaexacell2
192.168.2.52 uaexacell3
[[email protected] ~]#
2. Create the file with all the exadata storage cell .
[[email protected] ~]# cat << END >> exacells
> uaexacell1
> uaexacell2
> uaexacell3
> END
[[email protected] ~]#
[[email protected] ~]# cat exacells
uaexacell1
uaexacell2
uaexacell3
[[email protected] ~]#
3.Create the ssh key for the host.
[[email protected] ~]# ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa):
Created directory ‘/root/.ssh’.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /root/.ssh/id_rsa.
Your public key has been saved in /root/.ssh/id_rsa.pub.
The key fingerprint is:
15:ac:fb:66:8b:5f:32:09:dd:b9:e7:ca:6c:ef:6b:b4 [email protected]
[[email protected] ~]#
4.Execute the below command to make the password less login for all the hosts which we have added in exacells file. DCLI Utility configures the password less authentication across the nodes using ssh .
[[email protected] ~]# dcli -g exacells -k
The authenticity of host ‘uaexacell1 (192.168.2.50)’ can’t be established.
RSA key fingerprint is e6:e9:4f:d1:a0:05:eb:38:d5:bf:5b:fb:2a:5f:2c:b7.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added ‘uaexacell1,192.168.2.50’ (RSA) to the list of known hosts.

We have successfully configured the dcli utility on all the exadata storage cells. Now we can monitor & administrate cells nodes from the current host.
5.Let me check the status of the all exadata cells.
[[email protected] ~]# dcli -g exacells cellcli -e list cell
uaexacell1: uaexacell1 online
uaexacell2: uaexacell1 online
uaexacell3: uaexacell1 online

6.Create the griddisk on all the exadata storage node using the dcli utility.

Exadata Storage Cell Commands
It is not an easy to remember the commands since most of the UNIX administrators are working on multiple Operating systems and different OS flavors. Exadata and ZFS appliance are adding additional responsibility to Unix administrator and need to remember those appliance commands as well. This article will provide the reference to all Exadata storage cell commands with examples for some complex command options.
All the below mentioned commands will work only on cellcli prompt.
