3. Create aggregates and volumes

In this module you use the NetApp System Manager and command-line interface (CLI) and also how to create Aggregates, how to add disks, resize the volume, how create qtrees and delete qtrees.

An aggregate is the physical storage. It is made up of one or more raid groups of disks. Aggregates are collections of raid groups.  consist of one or more Raid Groups. I like to think of aggregates as a big hard drive.  there are a lot of similarities in this.  When you buy a hard drive you need partition it and format it before it can be used.  until then its basically raw space.  Well, that’s an aggregate.  its just raw space.

A qtree is analogous to a sub-directory.  lets continue the analogy.  aggregate is hard drive, volume is partition, and qtree is sub directory.  why use them? to sort data.  the same reason you use them (at least i hope you use them) on your personal PC.  There are 5 things you can do with a qtree you can’t do with a directory and thats why they aren’t just called directories.

Now let’s see how to configure a storage.

1st you have to go to storage which is on the left pane and at the right side you will be able to see the configuration wizard click on it, then it will load the configure aggregate page select manually create aggregates

As shown in the above picture click next

Give a name for your aggregate and on the disk selection select FCAL and click Next

—-> on the raid group select disks when the disk count is filled click on create and           it will be created.

even you can create aggregates by using the CLI (Putty) you have to type these commands. before creating aggregates through CLI you have to check the aggregate status to check this you have to type:
—> aggr status
—> aggr create aggr2 -b 64 4
