The following log files can be accessed either via console or SSH to VxRail Manager.

Monitor Dell EMC VxRail bring-up logs: dayone.log , short.term.log & firstboot.log:

  • dayone.log – detailed information in relation to initial first run configuration.
    • (/var/log/microservice_log/dayone.log)
cd /var/log/microservice_log/

# cat dayone.log
