Steps
1. Physically identify the logical last shelf in the stack.
Depending on your platform model and stack connectivity (multipath HA, multipath, single-path HA, or
single-path), the logical last shelf is the shelf having controller-to-stack connections from controller SAS
ports B and D, or it is the shelf having no connections to any controllers (because the controller-to-stack
connectivity is to the logical top of the stack, through the controller SAS ports A and C).
2. If the IOM12 shelf you are hot-adding is the initial IOM12 shelf being added to the IOM6 stack, meaning no
other IOM12 shelf exists in the IOM6 shelf stack, complete the applicable substeps.
Otherwise, go to step 3.
