NetApp 2050 disk shelf

hi,
I have a netapp fas2050 with 1 controller... just bought a ds14 to add. to it...wondering how to go about installing it..the attached pic should show what i think is needed.. also can this be done hot?.  I assume that the shelf can also have dual path to the filer.. is this correct.. fairly new to the Netapp so I need to get some answers before adding the shelf..

Thanks kindly
Ron

Dear Ottawaya,

If I understand you correctly - you have a FAS2050 (single-head/one controller) and have bought one DS14 shelf?
If that is the case, you can hot-add perfectly fine.
You will need the path from the FAS2050 0a to the "top" Controller 1's "in port".
You will need the path from the Controller 2's "out port" back to the FAS2050 0b.
Thereby you have achieved the "dual path".

Please also refer to the very fine guide from NetApp titled "DiskShelf14, DiskShelf14mk2 FC, and DiskShelf14mk4 FC Hardware and Service Guide" available via http://www.netapp.com/us/library/supportdocs/210-01431.html
Especially pages 84 and forth, but absolutely worth you read it closely.

Kind regards,
Soren

thanks for the tips... so to get it straight... fas2050 (0a) to ds14 "in" port on the top controller.. and the "out" port from the second Bottom controller to the (0b) port on the fas2050.... leaving an out port on the top controller and an in port on the bottom controller open..I am assuming that the controllers communicate internally within the ds14 shelf.. I only have 2 connector cables for this  so that would be perfect.. otherwise i would need 2 mors cable .. correct.. and I can do this hot.?...

Thanks for your input..

I have the disk shelf loaded... currently on the FAS itself we have 20 disks.. the new shelf has 14 disks and they show up in the manage disks report.. now i want to create an aggr with them but when i use the wizard it does not give the disks as an option.. what do  I need to enable to make an aggr out of the new shelf.. anyone?

Dear Ron,

Most likely in your single-head FAS2050 you now see the disks, but I could guess they are either "unowned" (or less likely owned by another system).
You can verify this from the CLI, by running the command: disk show -v
This may eventually tell you that the disks are "unowned" (in column owner this is blank for the newly added disks) or maybe owned by another system(which is less likely).
You must thus take ownership of the disks.
E.g. let's say you have a new disk 0a.49, then you take ownership of that disk from the CLI by running the commands:
priv set advanced
disk assign 0a.49 -s unowned -f
priv set

The first command brings you into advanced mode, the second assigns ownership of the disk to your system, and the third command brings you back to admin mode.

You can then repeat the above for each of the unowned disks.

I do assume you have an account to NOW (now.netapp.com), and you can through that read more about this via:
https://now.netapp.com/Knowledgebase/solutionarea.asp?id=kb40092

Please let me advice you to contact your NetApp support/integrator if the above does not bring you any further, as I do assume you are not all that familiar with Data ONTAP.

Kind regards,
Soren

ok so here i am... i have my shelf disks assigned to the netapp now.so i try to report on the shelves and low and behold not there.. the netapp shelf shows tho.. all disks are now listed as spare. but in the same pool as the first aggr. Being a newbie at netapp i am slowly getting there.. my goal is to use the new shelf as a new aggr1...I have 20 disks within the netapp itself but 4 are spares.. when i try to create a new aggr the new disk are not an option only the 4 spares from the netapp itself. I have been reading the man pages but am not getting a conclusive answer yet... any one have some guru help they can give..

Dear Ron,

you will need to remove the (new) spare disks from the aggregate.
I strongly advice you to contact NetApp support for this excercise!

I will however see what I can find for you, if you really want to take the risk...

Kind regards,
Soren
