Creating more than 2 logical disks via ACU (Proliant DL360 G6)

[Bardo]

Hi,

I have 4 physical disks in my Proliant DL360 G6 server.  2 disks are SATA, 2 are SAS.  I would like each disk to be represented as a single logical disk (i.e. NO raid).  I realise the SAS and SATA disks must be added to different arrays.  However, using the ACU, I cannot seem to configure more than 2 logical disks - once the 2 logical disks have been created, the option to create a new one is no longer presented.  As a result, my only option is to have both disks of the same type added as a single logical disk.  Am I doing something wrong?

Thanks very much
