What reasons could make HCL during an upgrade fail?

  • 1.  What reasons could make HCL during an upgrade fail?

    Hi,

    Recently, I upgraded FOS from v6.4.1a to v6.4.2a in a 3-switch fabric (all of them Silkworm 5300) and the ugprade itself failed with the following message:

    2013/03/11-17:20:47, , 2559, CHASSIS, ERROR, DS_5300B, HCL failed. Reboot the switch manually using the reboot command. However, it will disrupt the FC traffic.

    I had to manually reboot the 3 switchs in order to finish the upgrade. Previously I upgraded the other fabric (also with 3 Silkworm 5300) and it finished without issues.

    Does anyone know, which reason could lead to a HCL failure during the upgrade?

    I checked the FOS Message Reference guide and for this particular message, the tech writer did not racked his brain to define the cause...

    SULB-1037

    Message

    Probable Cause: Indicates HCL has failed. Many reasons, such as domain not confirmed, can cause this failure.

    Recommended Action: Run the reboot command to reboot the switch manually.

    Severity INFO

    Any advise is appreciated.

    Kind regards,

    Felipon

    HCL indicated "Hot Code Load"

    this behavior occurs when the upgrade cannot perform the FPGA Upgrade during firmwaredownload and commit.

    in such case you have to reboot the switch manually as indicated in the Switch Reference Message Guide.

    Thanks for the reply , but what I would like to know are the possible reasons of it. In this case, something fabric-wide must have prevented the HCL from performing the upgrade nondisruptively and I would like to know what could be, since the upgrade in the other fabric finished smoothly.

    Kind regards,
