Severity: 3-Major


When loading a UCS file from one iSeries model to a different iSeries model, the FPGA fails to load due to a symlink in the UCS file pointing to the firmware version for the source device. The system will remain in INOPERATIVE state, and messages similar to the following will be seen repeatedly in /var/log/ltm: -- emerg chmand[7806]: 012a0000:0: FPGA firmware mismatch - auto update, No Interruption! -- emerg chmand[7806]: 012a0000:0: No HSBe2_v4 PCIs found yet. possible restart to recover Dataplane. -- emerg chmand[7806]: 012a0000:0: Dataplane INOPERABLE - Incorrect number of HSBs:0, Exp:1, TMMs: 2 -- err chmand[7806]: 012a0003:3: HAL exception publishing switch config: Dataplane INOPERABLE - Incorrect number of HSBs:0, Exp:1, TMMs: 2 Note: Similar messages may be observed when there is a genuine issue with the BIG-IP HSB hardware.


FPGA fails to load; the BIG-IP system becomes unusable.


Loading a UCS from one iSeries model onto another model, for example, from an i7800 onto an i11400-ds, or from an i2600 to an i5600.


1. Update the symbolic link /config/firmware/hsb/current_version to point to the correct firmware file for the hardware model in use. Following are some examples: -- For the i2800: # ln -sf /usr/firmware/hsbe2v4_atlantis/L7L4_BALANCED_FPGA /config/firmware/hsb/current_version -- For the i7800: # ln -sf /usr/firmware/hsbe2v2_discovery/L7L4_BALANCED_FPGA /config/firmware/hsb/current_version -- For the i11400-ds: # ln -sf /usr/firmware/hsbe2_discovery_turbo/L7L4_BALANCED_FPGA /config/firmware/hsb/current_version 2. Reboot the system.
