5.6 SFA10K
• The SS2460 does not support SLOT POWER OFF feature and so the SET SLOT
POWER command has no effect on drives in the SS2460.
• The Management Ethernet port (LAN4) may boot running at 10 Mb/sec half-duplex,
instead of 100 Mb/sec or 1000 Mb/sec full-duplex. Typically, full Ethernet port speeds
can be restored by unplugging and replugging the Ethernet cable to the controller
port experiencing the slow speed. If the issue persists, please contact
[e-mail].
• On SS6000 enclosures the DISPLAY POWER_SUPPLY command may fail to display
the last three characters of the power supply serial number. This is only a display
issue, the command will complete successfully with no adverse effects other than the
truncated results.
• The SS6000 may encounter a problem where show enclosure commands will return
the following error message: “A command issued to an enclosure to get attributes for
the UI timed out.” This is an issue in the enclosure firmware v3.001 that is resolved by
upgrading to enclosure firmware v3.010.
• Powering off drives is not supported with 6KSSI interposers in the SS6000 enclosure.
If you issue the command, SET SLOT <encl-id slot-id> POWER OFF, the system
erroneously displays a success message. However, the drive power is not affected by
the command.

• After a controller shutdown the BMC WebUI indicates that the power is on.
If you are using the BMC WebUI remote power feature then after a SHUTDOWN
CONTROLLER or SHUTDOWN SUBSYSTEM the WebUI will indicate that the Host
power is still on and the button for turning the power back on is grayed out.
Resolution: Switch to another page in the WebUI and then back to the remote
power control page, this will update the page correctly. [BMC-50]
• IPMI Power Off does not always turn the canister completely off.
After a SHUTDOWN CONTROLLER or SHUTDOWN SUBSYSTEM, which ends with
an IPMI Power Off, the canister fan may restart and the LEDs may stay lit even
though the canister is in the shutdown or standby state.
Resolution: This condition makes it confusing to decide if the canister is shut down
or not. After a couple minutes, if you can’t communicate with the canister, it is shut
down. When in this condition, the power button may turn the canister off and on. If
the power button doesn’t work, then unseat the canister, wait 60 seconds, and then
reseat the canister. [FPGA78]
• SEP reset signals false power failure.
SHUTDOWN ENCLOSURE 1 RESTART results in a false power failure which causes
both canisters to save cache and restart. This is only a problem for the head disk
enclosure.
Resolution: SHUTDOWN SUBSYSTEM and manually power cycle the head disk
enclosure. [FPGA-81]
