System
status (green)
Off
(any) (any)
Power is not being provided by any power supply unit (PSU)
in the enclosure, or power is coming from the battery in the
canister.
If at least one PSU is powering the enclosure, the canister or
the enclosure midplane might be faulty.
If both node canisters in an enclosure indicate this state at
the same time, it is more likely that the enclosure midplane is
faulty. Reseat any node canister in this state, as described in
“Procedure: Reseating a Storwize V7000 Gen2 node canister”
on page 278. If the condition persists, replace the node
canister. If just one canister is affected, see “Replacing a
Storwize V7000 Gen2 node canister” on page 295. If both
canisters are affected, see “Replacing a Storwize V7000 Gen2
control enclosure midplane assembly” on page 352.
Flashing slowly
Power is available, but the canister is powered off. (The main
CPU is not running.)
Restart the node canister, as described in “Procedure:
Reseating a Storwize V7000 Gen2 node canister” on page 278.
Flashing fast
The node canister is doing a self test during start-up.
Wait for the canister to complete its start-up sequence.
