With the exception of the DCS3860 storage system initial power on, you should

Attention: After you remove a DDM FRU, wait for 90 seconds before replacing or
reseating it to allow it to properly spin down.

Replacing hot-swap hard disk drives

Problems with DDMs include any malfunctions that delay, interrupt, or prevent
successful I/O activity between the hosts and the DDMs in the storage expansion
enclosure. This includes transmission problems between the controllers, the ESMs,
and the DDMs. This section contains instructions to replace a failed DDM.
Note: If you want to remove a DDM that is not in a failed or bypass state, use the
IBM DS Storage Manager client program either to place the DDM in a failed state
or to place the array that is associated with the DDM (or DDMs) in an offline state
before you remove it from the enclosure.
Attention: Failure to replace the DDMs in their correct drawer and position
might result in loss of data. If you are replacing a DDM that is part of a configured
array and logical drive, ensure that you install the replacement DDM in the correct
drawer and position.
Before you begin, ensure that you wear an anti-static wrist strap.
