how to add disk shelf

[TDUBB1234]

I got a new shelf that i need to add to the netapp. any idea how to do this ?

how   do i put the sas cables in?

That is a simple question, and at the same time a loaded question. First off, call NetApp support if you are not comfortable doing this. They'll walk you through it.

My post is assuming you are running Multi-path HA.

If this is an HA pair I'd run the following options command on both NetApp controllers...

options disk.auto_assign off

Do not cable the shelf up yet. If the shelf has the same ID as another already running it could cause some issues. NetApp does a good job at keeping same shelf ID's separate, but...

Power on the SAS shelf, set the ID that you want the shelf to be. Usually odds are on controller A and evens on controller B (i.e. fas01-a 10-19, 30-30, etc, while fas01-b 20-29, 40-49, etc.)

After setting the ID on the shelf power the shelf off for 30 seconds. Wait 60 if you want to be sure... It takes some time for the ID to "burn in" and actually set itself.

Power the shelf back on, and add the shelf into the loop. I've stuck to the old school way of A --> D, C --> B. But if you don't know how to install a shelf I've probably lost you already.

Think of the square port as the "Stop" sign. That is where the loop "ends". So from fas01-a port A --> shelf1 Module A square. If you added a second shelf, Module A circle should go to shelf2 Module A square, this then goes to fas01-b port D.

I highly recommend calling NetApp support (you've paid for it might as well use it). Also I recommend reading the setup guide for your particular NetApp controller. It should show you exactly how to configure a single or dual controller configuration (way better than I can describe in words). Log onto the NOW site (now.netapp.com) and click on "Documentaiton -> Product Documentation -> Choose your FAS series -> Installation and Setup Instructions.

This document will show you how the cabling should look like.

Once you get the shelf added, you are going to need to assign the disks to the controller. If you want all disks assigned to one controller (which is recommended) run the "disk assign all" command on that controller. You'll then need to add the disks to the aggregate or create a new aggregate if the disk sizes/speed are different or you've reached your aggregate size limit, but you'll need to calculate the optimal raid group size as well. You don't want a small raid group or you'll run into performance issues.

This does not account for EVERYTHING and all scenarios, which is why it is a simple question but a loaded one.

What type of disk shelf are you trying to add? Information about how to add disk shelves can be found here.

http://support.netapp.com/documentation/productlibrary/index.html?productID=30147

Or, here is the direct link to how to hot add a SAS disk shelf for DS4243, DS2246, and DS4246.

I would agree with Ryan above and strongly suggest you open a case with NetApp support as a place holder. Be very cautious and thorough if trying this procedure on your own. As always be sure to make any sort of changes within an approved maintenance window and with a supporting change request.

how do i find out what disk shelf it is from command line?

[chute]

For DS42XX - sasadmin expander_map

For DS14MKX - fcadmin device_map

this is the result i got

so what is it?

why does fcamin device_map show blank?

[chute]

So I am going to say that the new one is most likely....

I think it's that one because the other loops only have 2 shelves. So before you probably had 4 shelves total and now you have 5 total. Yes/No?

Now run a 'disk show -n' to see if there are any unowned disks.

Also provide the results of 'disk show -v'

fcadmin shows blank because you don't have any of those shelves installed. You can ignore that it's blank. Its not an issue.

[TDUBB1234]

how can you tell that is where the new shelf is?

disk show -n shows nothing.

disk show -v

eq-ntap1> disk show -v

DISK OWNER POOL SERIAL NUMBER HOME

[chute]

How many shelves did you have prior to this event?

How many shelves are you attempting to add?

I can use that information with the results from below to answer your question. "how can you tell that is where the new shelf is?"

Enter privileged mode and issue the commands.

priv set advanced

disk show -n

disk show -v

[ryanbeaty]

Can you give us specs on your NetApp?

Model

ONTAP Version

The DS42xx and DS14MK2 aren't supported with everything.

Did you get confirmation that you are running a compatible configuraiton? WHen you add just one link from the NetApp to these shelves your NetApp should see the disks (disk show -n) <-- Non owned disks.

If you aren't seeing disks that means something is not either cabled right, or it isn't a supported config.

Run Config Advisor to check your cabling.
