Overview

In this section, we will learn how to manage the NetApp cluster. We will change the serial, disable and remove snapshots and others:

Disk Management (Simulator)

Now, in order to make some use of our Virtualised storage, we need to add some disks.

Enter System Shell

Before that however, we need to unlock the diag user. Diag user is a special type of user, used for administrative purposes and the most important thing is that it allows us to enter into the system shell:

Create Data Disks

Now that we are in the system shell we are ready to create the disks as follows:

Change the Path

Create the disks

Create SSD Disks

To add SSD disks, use the same command, just instead of type 23, we will add disks with type: 35

After that, we can safetly reboot the machine. Once the machines boots, we have to fix a common problem with the simulator. The simulator often crashes because of the insufficient space in the root aggregate. So, we have to assign all disks this node and remove & disable the snapshots

General Management

In this section we will review general disk management for both: simulator and real environment:

Assign Disks & Remove / Disable snapshot

After that we can reboot the server:

Once rebooted, we can assign disk to the root aggregate and increase the space in the volume:

Add disk & Increase space on the Volume

Firstly, we have to add the disk to the volume:

Once we have that we can increase the storage of the volume. Firstly, I will give him bigger number (1G) so I will see with how much I can increase it (in my case 888MB)

Privilege Levels

On NetApp, we have several privilege levels:

Admin - Most commands and parameters are available at this level. They are used for common or routine tasks.

Advanced - Commands and parameters at this level are used infrequently, require advanced knowledge, and can cause problems if used inappropriately. You use advanced commands or parameters only with the advice of support personnel.

Diagnostic (locked by default) - Diagnostic commands and parameters are potentially disruptive. They are used only by support personnel to diagnose and fix problems.

Let's see how to enter and use each of them:

Admin

The admin privilege is default privilege level which you have when you enter with the management IP and username & password which you specify when you create the cluster.

Code

As explained above, most of the commands are available in that mode.

Advanced

In advanced privileged level we have additional commands and options. Please be careful, as advanced should be used only with the instructions of NetApp support:

To elevate your privileges to Advanced level, use the following syntax:

Elevate to Advanced

We can check all the commands available in Advanced level:

Advanced Commands

The commands, ending with “*” are available ONLY in advanced privileged level.
