Error description

  • There are cases where the disk ping driver may stop returning

    stale.  This could cause the AIX CAA code to become confused
    about the state of other nodes in the cluster.

Problem summary

  • There are cases where the disk ping driver may stop returning

Problem conclusion

  • Modified the disk ping driver to ensure that ESTALE continues
    to be returned as long as the data is stale.
