Powering Off a Disk Shelf

If a disk shelf is a part of a storage pool, powering off or removing all SAS chains from a disk shelf will trigger a kernel panic on the controller(s) to prevent data loss, unless the disk shelf is part of an NSPF (no single point of failure) data pool. To avoid this, shut down the controller(s) before decommissioning the disk shelf, as described in Powering Off a Controller.

1. Place the power supply on/off switches to the "O" off position.
2. Disconnect the power cords from the external power source for the cabinet.

   Note:

   All power cords must be disconnected to completely remove power from the disk shelf.
