I have 3 Arrays in my system 1 for OS and 2 for data both data arrays are Raid-5 and each was showing 1 bad drive, so i shutdown the system and replaced both drives with a larger drives I checked in Adaptec Bios Array and it was showing both arrays rebuilding when i was exiting the bios setup, Array -1 was 2% and Array-2 was showing 1%, so i booted the system and after few hours i checked the process was complete and i restarted to check the status in the bois setup, there i was it was showing only 2 Arrays the 3rd was missing, when i tried rebooting the system it gave me this message The following arrays have missing required members and cannot be configured :Array#2-RAID-5 Press to accept the current configuration Press< Ctrl-A> to enter Adaptec RAID Configuration Utility Press to Pause Configuration Messages (Default is not to accept if no valid key pressed in 30 seconds) i selected the default to go on and boot, but system did not boot as it could not find the array and ask me to fix it, so just commented the mount in the fstab and booted i can not see the drives in the /dev folder can you please guide me on how to fix it? Thanks
