DataDirect Networks SFA™ OS 2.0.0 Release Notes Revision A1 | 16
• In an InfiniBand switch environment, an online upgrade causes an I/O error while
upgrading the second controller with SLES 10 SP4. In an FC environment, there are
no issues because the discovery rate is much quicker. The only option for SFA
upgrades with SLES 10 SP4 is to perform the upgrade offline.
To perform the upgrade offline,
1. Issue the CLI command
set subsystem offline.
2. Perform the controller firmware upgrade on both controllers.
3. Issue the CLI command shutdown subsystem restart.
4. After both controllers come back online, issue the CLI command
application show discovered
_initiator. This should report “No
discovered_initiators exist.” This will be the state until a read request for
information from those SCSI devices is issued. Once the devices are
accessed, there will be a small delay as they are rediscovered by the system.
5.4 SFA12K
• Only 180 (not 256) QLogic FC16 initiators are currently supported. This restriction
will be lifted in a future release. The number of FC8 initiators supported remains at
256.
5.5 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.
5.6 SFA7700 Early Access
• Ensure that each controller is connected to a network with an NTP server prior to
booting. A boot without a network connection can cause a BMC hang.
BMC-51 (4)
• Do not remove a controller canister while it is running unless otherwise instructed to
do so.
FPGA-22 (4)
• Power Button Operation is not fully implemented yet. There may be instances where
the power button on the canister does not operate as expected and may require the
canister to be removed and powered down outside of the enclosure.
