"n/a" means this state does not apply to this LED.
If the Controller Status LED is amber, restart the VTrak. See "Restart the
Subsystem" on page 112 or "Shutdown and Restart" on page 213.
If the Controller Status LED continues to display amber after startup, contact
Promise Technical Support. See "Contact Technical Support" on page 299.
The Dirty Cache LED flashes during input/output operation. If the LED shines
amber and the power is off, there is unsaved data in the cache. Do NOT remove
the cooling unit (M300f/i/p, M200f/i/p) or the cooling unit with the battery
(M500f/i/p) while this LED is on. See "Unsaved Data in the Controller Cache" on
page 295 for more information.
