Re-cable existing shelf into new loop
Hello,

We need to re-cable a shelf out of its current loop into a new one, just
interested to know if anyone had done this without issue?

We want to do this non disruptively so keen to hear other peoples comments and
thoughts on this and if possible without causing a panic.

Running 9.1P8.


Thanks

Dan

You did not provide any other details...
you want to remove from say 0a/0d stack and move to 1b/2c (or some other
supported version).

I think you could do one path at a time:
remove 0d (wait 45 seconds) plug shelf into 1b (or another square port)
(wait 45 seconds)
Verify the shelf is online
remove 0a (wait 45 seconds) plug shelf into 2c (or another circle port)
(wait 45 seconds)
Verify the shelf is on the new stack.

I think, if I recall, after some Patch release on 8.2 somewhere, the
hot-removal addition of the same shelf was fixed.

Additionally, I think you could take it a bit further (with a few more
commands):
system node run nodeb storage disable adapter 0d
system node run nodeb storage disable adapter 1b
remove shelf from 0d, plug shelf into 1b
system node run nodeb storage enable adapter 0d
system node run nodeb storage enable adapter 1b

system node run nodea storage disable adapter 0a
system node run nodea storage disable adapter 2c
remove shelf from 0a, plug shelf into 2c
system node run nodeb storage enable adapter 0a
system node run nodeb storage enable adapter 2c

Hi Tim,

Apologies on the other details, but you've assumed correctly anyway.

Was more interested to hear peoples experiences with it, as this is an SSD shelf
serving a storage pool keen to make sure it doesn't go belly up.

Trying to get a more official answer from NetApp about it.

Will let you know how it goes.

Thanks
