How to Power 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.
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. For
details on NSPF profiles, see “Choose a Storage Profile” in Oracle ZFS Storage Appliance
Administration Guide, Release 2013.1.5.0 .
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.
