Restarting a controller does
not disable the battery pack.
FPGA-27 (4)
Rare
If a power failure
occurs during a
controller restart
(SHUTDOWN
RESTART or SFA OS
Update) then the
controller will run on
battery power until it
completely drains the
battery pack.
Pressing the power button
may turn off the canister. If
the power button does not
work then unplugging the
battery pack will power
down the canister.
Spurious FPGA failure FPGA-
45 (3)
Rare
When the FPGA
crashes SFA OS will
report that the
controller's UPS
interface has failed.
When in this condition,
SFA OS will not detect
a power failure and
save its cache, so a
power failure may
result in data loss.
Perform a SHUTDOWN
SUBSYSTEM to force SFA
OS to save its cache to the
back-end disks. Then, a
hard power cycle is
required to reset the FPGA.
Since the FPGA is crashed,
there may be no way to do a
hard power off without
disconnecting the battery.
FPGA warm boot hang.
FPGA-74 (2)
Rare
The controller fails to
restart on a
SHUTDOWN
CONTROLLER
RESTART or
SHUTDOWN
SUBSYSTEM
RESTART. In this case,
no BIOS boot step is
displayed.
Manually power cycle the
controller by pulling and
reseating the canister.
SHUTDOWN does not shut
down controllers (continue to
run on battery).
FPGA-77 (4)
~50%
After a SHUTDOWN
CONTROLLER or
SHUTDOWN
SUBSYSTEM, the
canister appears to
shut down but if
enclosure power is
removed the canister
continues to run.
The power button may turn
off the canister. If not,
manually power cycle the
controller by pulling and
reseating the canister.
IPMI Power Off does not
always turn the canister
completely off. FPGA-78 (4)
~30%
After a SHUTDOWN
CONTROLLER OR
SHUTDOWN SUB-
SYSTEM, the canister
fan may restart even
though the canister is
in the shutdown or
standby state.
This condition is benign
except that it makes it
confusing whether the
canister is shutdown or not.
If all five canister LEDs are
off, then it did indeed shut
down.
A long pushbutton push does
not force the canister to power
off. FPGA-79 (4)
100%
A long pushbutton
push is supposed to
abruptly power off the
canister, but this does
not work.
Pull the canister and, if
necessary, use a short
pushbutton push.
FPGA update may restart
