Documentation says the C800 ships the inbuilt shelves with shelf ID 0 and 1. How do you change the shelf ID's of these? Understand different HA pairs can share the same IDs in the same cluster but we like to seperate them ideally? is it possible?

Yeh been through this doc, there is no hole to set each shelf up as its contained within the head so those instructions are wrong.

#

That's if its a seperate ns224 shelf

Ah - I see, I'll keep digging, but maybe some others can chime in too.

Confirmed in some documents, the Shelf ID of the Chassis itself cannot be changed. Only the NS224 shelves attached to it can be changed with the docs above that you were able to locate.

I don't recall a platform with built-in shelves ever being able to change shelf IDs.

the 2U FASs you can.

#

folks would do like 10,11,12. or 00, 01, 02.

#

it's clear on the 800s if you have multiple in a cluster which disk is with witch node though.

If I recall, like implied here already, there x250 model cannot modify the shelf id (a250/c250). Only external shelves

And for confirmation using the same shelf id's in different HA pairs in the same cluster is all cool isn't it?

Correct @ebon kindle - there are many clusters in the wild larger than 2 nodes, and if the shelf ID can't be changed, they must all be working fine 🙂 You're good to go! As @zenith locust pointed out, you can tell from the node name where a disk is located.

if you have multiple A800s (or C800s) in a cluster. you'll see disk IDs like -

1.0.x - nodes 01/02
2.0.x - nodes 03/04
3.0.x - nodes 05/06

etc.

Stack-shelf-bay. Too bad it doesn’t propagate all throughout (node shell doesn’t use stack-id, rather host adapter)

If you want to YOLO it, you don't even need to set unique shelf IDs on SAS shelves.. but it's an inelegant administration experience if you don't 🤣 (just so we're clear and scott and andris don't yell at me - set unique shelf IDs per HA pair for your shelves)
