Hot-Swap Drive Replacement - Lenovo ThinkAgile CP Part Replacement And Component Maintenance Procedures

Note: If you are reprogramming the controller model (canister board product): if they are mismatched on the
two storage controllers, ESM B (the top controller) enters lockdown mode. To remedy this, ensure that the
canister model on both storage controllers is the same. As necessary (if B is current active controller), failover
all traffic and applications to ESM A (bottom controller) and then hard-reboot ESM B.

Hot-swap drive replacement

Use this information to remove and install a hot-swap drive. You can remove or install a hot-swap drive
without turning off the storage, which helps you avoid significant interruption to system operation.
Notes:
• The term "hot-swap drive" refers to all the supported hot-swap NVMe solid-state drives.
• Use any documentation that comes with the drive and follow those instructions in addition to the
instructions in these topics. Ensure that you have all the cables and other equipment that comes with the
drive, as specified in the documentation.
• The electromagnetic interference (EMI) integrity and cooling of the storage are protected by having all
drive bays covered or occupied. The vacant bays are either covered by an EMI-protective panel or
occupied by drive fillers. When installing a drive, save the removed drive filler in case that you later remove
the drive and need the drive filler to cover the space.
