adding shelf / disks to an FAS2020

hello,

we have an FAS2020 with Disks in the head.

Now we want to add an additional shelf

i know how to plugin..

but thats it.

How can i add the "new" disks to the existing aggregate ?

Spare Disks.. etc.

Is there an How to ? Best practice ?

Thank you

Re: adding shelf / disks to an FAS2020

after connecting the shelf to the controller you should be able to see the disks on the commandline by

>disk show -n

Because of software-ownership you first must assign the disks to a controller

>disk assign 0a.16 -o <controller>

If options disk.autoassign is enabled, all the other disks are assigned automatically, otherwise use

>disk assign all -o <controller>

So now you should see the disks as spares by

>sysconfig -r

and from here you can add them now to an aggregate or create a new aggregate.

Don't you have a NetApp partner or consultant?

thanks -

we have an partner / consultant... but.. save money....

so i had to do this

Re: adding shelf / disks to an FAS2020

btw..

is there an problem:

Raid4 config Fas2020 head

adding this shelf to an existing aggr. ?

Has this shelf then Raid 4 too ?

Re: adding shelf / disks to an FAS2020

If you extend the aggregate formed by internal disks with disks of the external shelf, then: yes, it will stay raid 4 because this is the aggr option.

Has the external shelf the same disk types and sizes as the internal disks?

If not, be careful what you do.

internal we have SAS 15000 (pysical 410 GB - netapp na_admin)

the new shelf DS14MK4 has 14 x 450 GB SAS

Re: adding shelf / disks to an FAS2020

If you extend the aggregate formed by internal disks with disks of the external shelf, then: yes, it will stay raid 4 because this is the aggr option.

Or you can change RAID type before adding more disks.

Re: adding shelf / disks to an FAS2020

So you have the same disk type.

Theoretically you could extend your aggregate by the external disks.

Personally I would refrain from that. The shelf is then bound to the controller - if you need to upgrade to a more performant/newer/bigger/... system, you need more steps for migrating the data.

But there are different opinions around that....

Re: adding shelf / disks to an FAS2020

I'm agree with Mark.

IMHO, for the FAS2000 family, you shouldn't mix internal disks with shelf (external) disks.

NetApp: Enjoy it!

does changing the raid type has any effects on existing data ?
