Error description

  • Failed to condense snapshot copies of volume because IBM
    Spectrum Protect Plus could not find any snapshots to destroy.
    When IBM Spectrum Protect Plus attempts to delete older
    snapshots at the end of a backup job or during a Maintenance
    job, the snapshot deletion may time out due to I/O bottlenecks.
    The next backup/maintenance job retries the deletion request,
    but vSnap did not correctly return the status code to indicate
    that the snapshot had already been deleted.

Problem conclusion

  • When IBM Spectrum Protect Plus attempts to delete older
    snapshots at the end of a backup job or during a Maintenance
    job, the snapshot deletion may time out due to I/O bottlenecks.
    The next backup/maintenance job retries the deletion request,
    but vSnap did not correctly return the status code to indicate
    that the snapshot had already been deleted. This has been
    resolved.
