eddyc Posted March 31, 2013 Posted March 31, 2013 Hi all, Does anybody have this server. I've bought two to use a backup servers with a set of 4tb drives. When I go into the raid config, it lets me make a virtual disk with the two drives as a mirror, but only sees 1.8tb of the 4tb drives. I'm sure I am missing something obvious but have been chasing this around for a while now. Any pointers would be appreciated. Cheers, Ed
GTX Posted March 31, 2013 Posted March 31, 2013 Is the motherboard able to use that much in one Disk? Its best to check teh website to see if it recognizes such a big drive. If it does, Try updating the firmware This is a stab in the dark but its the only thing i can think of. Rick
eddyc Posted March 31, 2013 Author Posted March 31, 2013 Hi Rick, I've looked through the specs of the controller and the server on the HP website and cannot find anything relating to disk sizes - it just says that the controller supports a maximum of 2 virtual disks. I was going to try a firmware upgrade, but they only appear to list Linux updates and nothing for Windows :-( I'm really at a loss and have been chasing my tail on this for a while!
SYNACK Posted March 31, 2013 Posted March 31, 2013 Probably not what you want to hear but it may not support it at all, 4tb drives have to use a different cluster size which most bioses and hardware do not support at the moment. This is why many are usb interface only so they can bundle a controller in there. A future firmware update may fix it but you may have to specificly look for a raid controller that can support it.
synaesthesia Posted March 31, 2013 Posted March 31, 2013 To add a little more info to that, you'll need to use GPT rather than MBR when partitioning them, and I think you need a 4k cluster size as opposed to 512k. Some bioses/raid cards will have an emulation feature to allow that, otherwise use the RAID utility to split the drive down, again if supported.
DMcCoy Posted March 31, 2013 Posted March 31, 2013 Also something to remember is that Windows server backup before 2012 doesn't work with 4k sector drives.
eddyc Posted March 31, 2013 Author Posted March 31, 2013 Thanks for all the advice so far everybody. We are using these drives with veeam. We've got a HP micro server working with these exact drives but just can't get the big drives to work in these servers which is a shame :-(
DMcCoy Posted March 31, 2013 Posted March 31, 2013 From the 110G6 specs page: NOTE: HP Smart Array B110i does not support greater than 2TB hard drive. 1
eddyc Posted March 31, 2013 Author Posted March 31, 2013 Pants! I'm guessing that hasn't changed between the G6 and G7... External caddy it is then. Thanks so much
Arthur Posted March 31, 2013 Posted March 31, 2013 Also something to remember is that Windows Server backup before 2012 doesn't work with 4k sector drives. I thought the solution for that was to simply reformat the drives?
DMcCoy Posted March 31, 2013 Posted March 31, 2013 I thought the solution for that was to simply reformat the drives? Microsoft support policy for 4K sector hard drives in Windows An update that improves the compatibility of Windows 7 and Windows Server 2008 R2 with Advanced Format Disks is available Depends on the type 4k native or 512E Windows server backup uses a VHD, VHDs do not work on 4k native drives with 2008/7
