FAS3160 add DS14mk4 disk shelf

[LIUXUAN55]

Now I have a question about how to add a DS14mk4 in existing loop in the FAS3160 storage system.

My now topology is like this.

between NAS02A and NAS02B made the metiocluster.

Now i bought 6 DS14mk4 disk shelf want to add this in this NAS systems.My hope topology is below:

My question is ,is there have some problem about my hope topology?

and how is the step about adding shelf by online hot-adding  or offline adding?

Can I add the 6 shelf at the same time when I made a offline adding?

And I am also thinking about if I use the offline to adding shelf in FAS3106,the machine have run in more than 700days that doesn't do any shutdown or restart ,If I turn off the FAS3160 ,what will happened? I heart about sometimes if  turn off the controller,It will not turn on normally,and what happened will I  meet.

Thank you very much!

Hi aborzenkov.

Thank you very much!

And do you know how to add a shelf offline?

I think maybe liks this:

     1.turn off any I/O

     2.Power off my storage head on both node

     3.turn on my new shelf (If I want add more than 1 shelf one time,Then I  link the new shelf together first)

     4.link the cable to the loop

     5.turn on my storage head

Is this right?

[aborzenkov]

Yes, you are right.

You can also add new shelf online, without downtime. Documentation on support site has step by step instructions how to do it.

Supported limit is 6 shelves per loop. So unless you have explicit confirmation from NetApp, this configuration will be unsupported.

Hi aborzenkov.

Thanks a lot.

Do you know which document show that each loop limits is 6? I can't read this limit before.

You can find configuration limits in System Configuration Guides on support site.
