Issue

Freq.

Customer Impact

Resolution

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

Rare

After a BMC/FPGA

Reseat canister or power off
