Resetting Your System after a Crash or Hang

If the DRAGEN system crashes or hangs, the dragen_reset utility must be run to reinitialize the hardware and software. This utility is automatically executed by the host software any time it detects an unexpected condition. In this case, the host software shows the following message:

  Running dragen_reset to reset DRAGEN Bio-IT processor and software

If the software is hanging, please collect diagnostic information as described in subsection Sending Diagnostic Information to Illumina Support and then execute dragen_reset manually, as follows:


Any execution of dragen_reset requires the reference genome to be reloaded to the DRAGEN board. The host software automatically reloads the reference on the next execution.
