CAUTION:
To properly ventilate the system, you must provide at least 7.6 centimeters (3.0 inches) of clearance at the
front and back of the device.
CAUTION:
When removing or replacing a failed component, allow 30 seconds to pass before inserting a
replacement component. This time is needed to allow the device to clear out the system registries.
CAUTION:
Schedule physical configuration changes during periods of low or no activity. If the system is performing
rebuilds, RAID migrations, array expansions LUN expansions, or experiencing heavy I/O, avoid physical
configuration changes such as adding or replacing hard drives or hot-plugging a controller or any other
component. For example, hot-adding or replacing a controller while under heavy I/O may cause a
momentary pause, performance decrease, or lass of access to the MSA while the new controller is
starting up. When the controller completes the startup process, full functionality is restored.
CAUTION:
Before replacing a hot-pluggable component, ensure that steps have been taken to prevent loss of data.
