Things to know – service action allowed LEDs
Each controller canister, power-fan canister, and battery canister has a Service action allowed
LED. The Service action allowed LED lets you know when you can remove a canister safely.
Notice!
Possible loss of data access
Never remove a controller canister, a power-fan canister, or a battery canister unless the
appropriate Service action allowed LED is on.
If a controller canister or a power-fan canister fails and must be replaced, the Service action
required (fault) LED on that canister comes on to indicate that service action is required. The
Service action allowed LED also comes on if it is safe to remove the canister. If data
availability dependencies exist or other conditions that dictate a canister should not be
removed, the Service action allowed LED stays off.
The Service action allowed LED automatically comes on or goes off as conditions change. In
most cases, the Service action allowed LED comes on when the Service action required (fault)
LED comes on for a canister.
If the Service action required (fault) LED comes on but the Service action allowed LED is off
for a particular canister, you might need to service another canister first. Check your storage
management software to determine the action that you should take.
When a service action is required for a controller canister, you must place that controller
offline before removing it from the enclosure. This prerequisite ensures that the storage array
maintains accurate expansion cabling.
