Powering Off the Disk Shelf
2.
Slide the top cover rearward 0.5 in (13 mm) and lift it straight up and off the
chassis (2), and set the top cover aside.
Powering Off the Disk Shelf
Most disk shelf components are hot-swappable; you do not need to remove power when
replacing them. Do not remove a component if you do not have an immediate replacement. The
disk shelf must not be operated without all components in place.
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
shelf is part of an NSPF (no single point of failure) data pool. To avoid this, shut down
the controller(s) before decommissioning the shelf, as described in “Powering Off the
Controller” on page 50.
1.
Stop all input and output to and from the disk shelf.
2.
Wait approximately two minutes until all disk activity indicators have stopped
flashing.
3.
Place the power supply on/off switches to the "O" off position.
