Service Action LEDs
ATTENTION
Possible loss of data access – Never remove any canister unless the
appropriate Service Action Allowed LED is turned on.
Each canister in the storage enclosure has two service action LEDs.
•
Service Action Required LED – This LED comes on to indicate that a condition
exists that requires service.
•
Service Action Allowed LED – This LED comes on when it is safe to remove a failed
canister. If there are data availability dependencies or other conditions that dictate
that 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.
IMPORTANT
If the Service Action Required LED is 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.
NOTE
In most cases, the Service Action Allowed LED comes on when the Service
Action Required LED is on for a canister.
