When I create an aggregate, what size of number using "-disksize" options in Clustered Data Ontap?

[KHYOON123]

Hi all,

I attemped creating an aggregate.

My system has an different of mixing disks. 600GB, 450GB..

I want to create an aggregate contains 600GB disks.

For example,

::> aggregate create -aggregate aggr1 -diskcount 5 -disktype "???"

If I make an aggregate all 600GB.

What size of the number?

I don`t know how to measure that.

Thanks.

Hi,

disk-type specifies the Data ONTAP drive type. This option is needed when creating aggregates on systems that have mixed drive types or both drives and array LUNs.

for example : FCAL, SAS,SSD etc.

thanks

-disksize  specifies the size, in GB, of the disks on which the aggregate is to be created. Disks with a usable size between 90% and 105% of the specified size are selected.

You can choose -disksize as 600GB, am I answering your question? If not, can you give me more clarity on the question please?

Thank you for your reply.

My answer is wrong.

not -disk-type, -disksize is right.

What size is specify GB?

Physical size or other size?

In 7-mode, If I create an aggregate contain 600GB, 5disks

> aggr craate aggr1 600@5

How do I same thing in Clustere Data Ontap?

Many Thanks.

Oh, "-disksize" means aggregate size?

I thought "-disksize" that means per disk size in an aggregate.

Thank you so much.

My installed System Has 24 450GB disks and 24 600GB disks.

If I create an agreegate only using 5 450GB disks.

So how do I creat an aggregate do not mixed 600GB Disks?

Shuld I use options for particula disks?

Thank you.

Hi,

-disksize is the size per disk, not the total aggr size. you can see this link for more info about parameters which can be used https://library.netapp.com/ecmdocs/ECMP1511539/html/storage/aggregate/create.html

Thanks
