Process for adding/removing stack members in DNA fabric

[scsc_tech]

Is there a new process for adding/removing stack members to a DNA fabric enabled switch or is it much like a tradition stack membership change from the switch console?

remove a switch from a stack

1) power it down and them unprovision it

2) recable  the existing switches stackwise cables

3) perform no switch  xx provision xx

add switch to existing stack

1) on existing stack - switch xxx provision (type of switch your adding)

2) on new switch change switch priority to a value higher then the existing master then  save and power off 

3) connect stackwise cables

4) power on new switch member

Im hoping someone can assist with a simple answer if my assumption is correct

you are right except "on new switch change switch priority to a value higher then the existing master then  save and power off", if you want the new switch to be master (now called Active) then only you do what you have mentioned above, chances are your current active is already configured with priority 15 in that case if you configure the new switch also with priority 15 then the switch with lowest MAC will become Active.

if you want the new switch to join stack as member, just configure it with priority lower that you current Active and Standby in Stack.
