APAR status

  • Closed as program error.

Error description

  • Even though the packet rate (or PKEY, MTU, q_key) is
    specified by the Subnet Manager in IPoIB environment,
    AIX is not using the specified value and this may block
    other infiniband interfaces from joining the multicast
    groups in the same subnet.
    

Local fix

  • N/A
    

Problem summary

  • If a customer requires to change the packet rate value in the
    Subnet Manager, the AIX interfaces will not use this value
    and they will create a multicast groups with the maximum
    rate available in the line. This will cause ofther members
    in the network that follow this rule, to fail the join to the
    multicast group.
    

Problem conclusion

  • During the process to join the multicast group in the IPoIB
    code, verify if the query of the multicast group had
    the packet rate and other values set, if so, use this values
    and set the mask to indicate the SM that we will be using
    those values.
    

Temporary fix
