Doc Type: Bug Fix
Doc Text:
Previously, illegal configuration values for the parameters scsi_rescan_minimal_timeout rescan_maximal_timeout caused forceIscsiScan to throw an unhandled exception. This was due to a mistake in way that logging methods parsed arguments: the first argument was read as a message, and the other arguments were read as format values and options. A patch, which makes use of the implicit string concat feature, ensures that these unhandled exceptions are not thrown because of wrongly parsed parameter values.
