Serial Data Capture

iDRAC allows you to capture console redirection serial for later retrieval with the use of the Serial Data Capture feature. This feature requires an iDRAC Datacenter license.

The purpose of the Serial Data Capture feature is to capture the system serial data and store it so that the customer can later retrieve it for debugging purpose.

You can enable or disable a serial data capture using RACADM, Redfish, and iDRAC interfaces. When this attribute is enabled, iDRAC captures serial traffic received on Host Serial Device2 irrespective of serial Mux mode settings.

To enable or disable Serial Data Capture using iDRAC UI, go to Maintainance > Diagnostics > Serial Data Logs page, and select the check box to enable or disable.

NOTE:
  • This attribute is persistent over iDRAC reboot.
  • Firmware reset to default disables this feature.
  • While Serial Data capture is enabled, the buffer keeps getting appended with recent data. If the user disables Serial capture and enables it again, iDRAC starts appending from last update.

The System serial data capture starts when the user enables the serial data capture flag from any of the interfaces. If serial data capture is enabled after the system has booted, you have to reboot the system, so BIOS can see the new setting (console redirection Enabled requested by iDRAC) to get the serial data. iDRAC will start the data capture continuously and stores to the shared memory with a limit of 512 KB. This buffer is circular.

NOTE:
  • For this feature to be functional, one must have Login privilege and System control privilege.
  • This feature requires an iDRAC Datacenter license.
