virtual disk drive failure

First, the PXE message is not an error - it is simply the boot option following the hard drive (which failed).

So, you only had ONE drive in "RAID" on this server? So, did you have a PERC 6 or H700 RAID controller? Need to know which one you have in order to tell you if you have any options at this point.

I have a perc6 i believe, how can I tell?

I have a perc s100 bios controller

Yeah, you can install OMSA (if it isn't already installed) and check for the drives/controller under Storage.

windows server 2008r2

Which one? The S100 is built-in, so it is possible for you to actually have both the S100 and the PERC 6/H700.

To tell: you can check your order details, you can look in the CTRL-R utility during POST, check the iDRAC, or check in OMSA.

Which OS do you have?

What do you mean?

i have the perc 6

I installed it and attempted to connected via omsa and it doesn't connect, 

You tried https://servername:1311, https://localhost:1311, and https://ipaddress:1311? It actually said exactly that "communication failed"? or that the webpage could not be displayed?

If it won't connect to any of the above, do the install again ... use the default settings (do NOT change any of the settings, including the web server portion - this IS the connector for OMSA).

I tried connecting with the IP address and host name and it says communication failed.
