Error description

  • This problem only affects IBM tape drives if these tape device
    names are always changed frequently on the SAN.
    When the SAN discovery successfully finds a new tape device to
    an IBM tape drive for an error code as ERROR_FILE_NOT_FOUND, it
    always converts an IBM tape device file name format got from the
    HBAAPI as TapeX to a name format as \\.\TapeX. This new file
    format is stored in an internal array for a further device
    serial mismatch checking. When it detects a serial number
    mismatch for this device \\.\TapeX just found, it will find a
    new device as TapeY from the HBAAPI immediately. This new device
    file will replace the one found previously as \\.\TapeX to this
    internal array. Since this array is not initialized, the device
    file name in this array will become as TapeYapeX.This is an
    invalid device file name on Windows platforms, the SAN discovery
    is not able to open it to get the device serial number.So the
    SAN discovery will fail to update a device path when the device
    serial mismatch occurs to this device.
