I inherited a Dell 1900 from my employer and wanted to install WHS. While attempting to install, I'm prompted with "Hard drive capable of hosting Windows Home Server was not found. Would you like to load additional storage drivers? My RAID is LSI 5.0.1 PERC 5/I. I've gone to the Dell 1900 driver page and downloaded the appropriate SAS drivers and extracted to a USB drive which I attached prior to booting. Still no joy as WHS can't find any drivers.
Are you installing WHS 2008 or 2011?
Keep in mind that the PERC does not support non-RAID, so unless you configure RAID BEFORE booting to the OS installation disk, the OS won't be able to see the hard drives even if you have the right drivers.
Go to CTRL-R during POST to configure AND initialize RAID.
It's WHS 2011 and the RAID was already initialized at 100% per the boot up. However, I went ahead and removed the old one and started a new one. I initialized the RAID-5 set up that I configured and still no joy on the WHS install.
I went to the LSI site and downloaded the W7x64 and 08R2 x64. It finds it ok, starts to act like it's working...then stops and ask for the driver again.
Both Windows 7x64 and 2008R2 should have the drivers built-in, so Dell does not have special drivers for this hardware/software combination; assuming RAID has been configured/initialized, it should just work. Drivers often have a minimum supported firmware level, and even though the PERC 5/6 use the same drivers, the support is based on firmware level. Because we are talking about a PERC 5 instead of the PERC 6, it may be even more sensitive to the firmware on the card. The only other thing I could suggest is upgrading your PERC 5 firmware to the latest. It is possible that even this is not high enough, that the built-in driver (or even third-party driver) needs a higher firmware for compatibility than even the latest PERC 5 firmware has. If it doesn't work with the PERC 5 at the latest firmware, I "might" go so far as to say that the PERC 5 is not supported and you would need a PERC 6/i to get it to work. One other option with the PERC 5 might be to try an older version (use Other Versions link on download page) of a Vistax64 or 2008x64 driver. I'm afraid that's all I have left - a quick Google search did not yield a successful installation that I saw.
It shouldn't affect the ability to install the OS (just the ability to use the full storage), but is your raid virtual disk over 2048GB (2TB) in size?
