I have an HP ML110 G5 ProLiant server that I am getting ready for a job, I inserted two new 1TB drives, configured RAID1 in the pre-boot environment using the HP embedded RAID controller and it shows as a single logical array pre-boot. When installing Server 2008 Foundation it was seen as a single disk but now the OS is installed if I go to Computer it shows the disks individually. Each disk has the windows files on it so I guess the installation was correctly put on the array but I created a test txt file on the C:\ and this was not mirrored onto the E:\. Now I am concerned that the RAID1 array is not functioning correctly and there is no disk tolerance for mechanical failures.
Any assistance appreciated, I followed the same setup on various ProLiant Microservers and it worked on all of them but they used server 2008 r2.
Cheers
EDIT: It is an Adaptec Serial ATA HostRAID apparently. Device Manager shows all drivers are installed but perhaps something is preventing the OS from seeing the Array correctly so it is just booting off of one drive and showing the other as a slave?
Device manager lists the RAID controller as "Intel Desktop/Workstation/Server Express Chipset SATA RAID Controller" Hardware ID: "PCI\VEN_8086&DEV_2822&SUBSYS_31F4103C&REV_02" Driver 13.0.1.1000 26/02/2014 (Probably installed by my DriverUpdater USB).
