ESXi 5.5 won't see datastore when installed on HP SD flash card

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?

Have you selected Add Datastore, and follow the wizard? This should show the unused/unalloted space, for you to create (format the new datastore with VMFS).

Select the Host > Configuration Tab > Storage > Add Storage (which should really mean, create new datastore, or format as VMFS)

When you install ESXi 5.5 on the RAID 5 volume, the remainder of the volume, it prepares as VMFS, because it's disk0.

If you install on Disk0, it never formats the second disk Disk1, as a datastore.

If after hitting Add Storage, no storage appears, to create the VMFS datastore.

Can you check Storage Adaptors, and confirm if you can see the RAID controller?

also if you see this link

http://h18004.www1.hp.com/products/servers/vmware/supportmatrix/hpvmware.html

it states for your ML350p gen8

(4) Successful installation of the VMware operating system requires either the HP custom ESXi image or an OS image can be created with VMware's ImageBuilder application that has, at minimum, appropriate device drivers to support the boot controller and at least one network device in the server. A list of drivers included in the HP Custom Image is available here.

(5) Includes support for Intel® Xeon® processor E5-2600 v2

(6) Supports HP ESXi Offline Bundle for VMware vSphere 5.5 version 1.5 and forward

So are you using the OEM HP software from HP above?

thx!

1. It works both, on the custom HP iso and the standard VMware 5.5i iso

2. your suggestion " When you install ESXi 5.5 on the RAID 5 volume, the remainder of the volume, it prepares as VMFS, because it's disk0" waked me up.

If you don't use the raidvolume for the VMware installation, you have to configure i in the vSphere client. That did work.

It's the way the installer prepares and partitions the disks. But I also like to think of it, as if you had data in the disk.... it would not overwrite it by accident!

no problems!
