Error description

  • While transferring/writing/storing to IBM COS (formerly
    Cleversafe) the following error message may be seen:
    ANR3731E A request to the cloud service provider for the write
    object operation on the <Cloud Pool Name> storage pool failed
    with the 503 HTTP status code
    A 500 HTTP status code may also be seen.
    
    The IBM COS has had a problem completing the write requests from
    the IBM Spectrum Protect server due to the size of the
    multi-part objects being sent and the frequency of the retries
    when a failure occurs. This APAR is being taken to change the
    part size the server is sending to a larger value and increase
    the retry time to avoid causing these failures in the IBM COS.
    Note that these failures can occur at cloud pool ingest time
    when there is no directory container cache in the cloud pool. Or
    they can occur at data transfer time when there is directory
    container cache in the cloud pool.
    The dsmffdc.log may also show the following:
    [ FFDC_GENERAL_SERVER_ERROR ]: (sdcloud.c:3567)
    com.tivoli.dsm.cloud.api.ProviderS3 uploadFile Retrying upload
