press C on post screen and see the status of the drives, if the configuration is gone then you need to check the HDD status, power cycle the server once, try again if no configuration then create new raid and for sure the data is lost if there is no configuration on controller, update me if anything needed
Hi guys  was wondering if someone could give me solutions to these issue: 1. When my r420 boots up I get this pause before it goes into the operating system which I have to continuously have a keyboard plugged in to press enter so I can bypass it (all of the disks from your previous configuration are gone ……..etc. press any key to continue or press C to load the configuration utility.)   2. If I try do a mass update with the domain name (downloads.dell.com) in either the life cycle controller or IDRAC I get this critical error:  (unable to connect to network share SWC0066) If someone could advice a workaround these issues would be greatly appreciated.  
Post boot up paused by error and mass firmware upgrade not working
