Hello,
I have created Raid 1 with two 500Gb HDDs on HP Proliant ML310e Gen8. Raid controller showed it has been succesfully created and disk size is 465Gb. But when i want to install VMware ESXi 5.5, it shows two separate hard drives. What could be the problem with Raid controller? HP B120i Raid Controller.
Best regards,
Elvin Mammadov

SolutionYou need to install the HPE ESXi image as the RAID controller requires a special driver. Without the driver the OS reports two separate disks. This controller is software based RAID, all raid functionality is provided by the driver

Re: Created Raid 1, but shows two separate hard drives
We have the same issue on the other server, HP Proliant DL120 G5. Though I have created Raid 1, either Windows Server or VMware ESXI see 2 hard drives instead of 1 hard drive. What causes this to happen?

Re: Created Raid 1, but shows two separate hard drives
The DL120 G5 is the same answer. The embedded SATA controller is a software RAID controller and requires a special driver that provides the RAID functionality. To avoid this you need either an E Series or P series based Smart Array controller which are hardware RAID controllers. Most OS's have drivers to support the hardware based controllers.
