Today i installed a HP 4Gb flashdisk on a new HP ML350p gen8 server with Bion P72 (newest). This server contains 4 300GB SAS disks in a RAID5 config with 1 Logical drive. This drive works fine. When installing a direct Windows server on it, the logical drive show up.
When installing ESXi 5.5 i can choose 2 location to install to, one SD flash disk and the SAS logical disk. I installed it on the SD flash disk. But after that i start the vSphere client and no datastore is being seen there. The RAID5 logical disk isn't there.
When installing ESXi 5.5i directly on the Raid5 Logical volume, vSphere sees the logical volume and can use it.
How can i install ESXi 5.5 on the HP SD flash disk and use the logical disk as datastore? Why can't i see that disk now?
