Hi, hopefully a quick question but does anybody know how to populate 12 disks in the internal slots for a C30 system? The KB is mentioning to check on HWU to look at alternate views but there isn't any that shows anything with disks for a C30 system.

Not an answer to your question but I agree that it is a bit strange that the C80 is the only one in the C-series with the alternate views for disk positioning.

yeah also trying to chat with support to see 🙂

#

they come with the same kb I found: https://kb.netapp.com/on-prem/ontap/OHW/OHW-KBs/How_to_partially_populate_a_controller_with_an_internal_shelf_with_drive

All 2U platforms:
outside -> inside

#

meaning 0,1,2,3 - 21,22,23
to start, then 4 & 20 and then 5 & 19, and so on

#

The 4U platform have extra bridges that require the different placement

#

so in my case then: 0,1,2,3,4,5 and 23,22,21,20,19,18

#

thanks a lot will try it 🙂

You may need/want to re-init system to take advantage of smallest root possible (all-data wiped)

yeah that's no problem it's not used yet

#

was trying option 4 and 9a / 9b already but controller 2 kept failing

#

it will. One node "owns" the left and the other "owns" the right. if one has no disks to "own" it will not go

#

and then have to redo - 9a/9b

#

yeah but now the disks are also installed a bit weird in slots 2 - 15

#

but I'm remote trying to install it so it's a bit difficult 🙂

@junior carbon it worked fine after reseating the disks, thanks again
