Hi,

I'm planning to use proxmox as a hypervisior on a Dell PowerEdge R610 which will be installed on USB drive and the local drives are storage for the server to see as storage. When i installed proxmox everything installed correctly but the host didn't see the local raid storage from the perc H700.

Thank you in advace for your help.

Looks like your HW raid is not a real but a so called "fake" raid, which is only known by certain OS-es (Windows in most cases).

Disable the raid function and use each disk a one blockdevice in Proxmox.

Dell PERC H700 definitely *is* true hardware-raid controller. It is based on SAS2108 SoC and supports raid5/6 too. But unlike IBM/Intel/Fujitsu/etc controllers based on SAS2108, H700 does not use reference LSI-design. Probably because of that, standard "megaraid" (megaraid_sas, megaraid_mbox) linux kernel driver can not find it.

IIRC, Dell PowerEdge with PERC needs mptsas/mpt2sas kernel module. But I do not have any Dell around, so I can not test it...
 
Installed Debian 9 on a Dell R510 with PERC H700 (build hw raid 10) without any problems, no need to manual load raid drivers during installation.
