I am making plans to remove three unused shelves from a 7-mode system. The three shelves form a complete stack so it's pretty straightforward, however I noticed that one of the three shelves contain about half of it's disks with one slot/port and the other half with a different slot/port. I don't know if this is common or not. The other two shelves show the same slot/port on each disk.
Any thoughts/ideas? Is this a concern?
Some disks on shelf 21 look like this: 3d.21.0, 3d.21.2, 3d.21.4
The others look like this: 5a.21.1, 5a.21.3, 5a.21.5
