status (green)
(green)
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
Off
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
(any) (any)
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.
Power is available, but the canister is powered off. (The main
CPU is not running.)
Flashing slowly
Restart the node canister, as described in "Procedure:
Reseating a Storwize V7000 Gen2 node canister" on page 278.
The node canister is doing a self test during start-up.
Flashing fast
Wait for the canister to complete its start-up sequence.
