This is an SOS. I have an R720 dell server with a corrupt operating system. The hard drive has an existing Raid 5 array with 6 hard disks (300gb sas firmware e66) prior to this time. I systematically rebuilt one of the hard drive with 300gb sas firmware e62. and replaced another that is blinking amber with 300gb sas firmware e66.
The raid 5 was rebuilt successfully according to Dell Bios and configuration utility. However i notice the Raid 5 array or the drives are not detectable on windows 2008 server instead i got an error message - \Boot\BCD error ... An error occured while attempting to read boot configuration drives.
Questions Is it safe to mix an hard disk of lower firmware with hard dirves of higher firmware.
Can i update lifecycle controller as it is requesting for update ?
