Replace Drive In A De6400 Array - Lenovo ThinkSystem DE6400 Manual

When inserting fewer than 24 drives into a DE6400 or DE6600 controller, you must alternate
between the two halves of the controller. Beginning with the far left and then moving to the far right,
place the drives in one at a time.
The following figure shows how to stagger the drives between the two halves.

5.2. Replace drive in a DE6400 array

You can replace a drive in a DE6400 array.
DE6400H and DE6600H support SAS expansion with both 2U and 4U shelves. DE6400F and
DE6600F only support 2U24 with SAS SSDs.
Follow this procedure to replace a drive in a DE6400 (24-drive shelf).
About this task
The Recovery Guru in ThinkSystem System Manager monitors the drives in the storage array and
can notify you of an impending drive failure or an actual drive failure. When a drive has failed, its
amber Attention LED is on. You can hot-swap a failed drive while the storage array is receiving I/O.
