My old case was a rack mountable server with 12 bays, I have since well outgrown that and was attempting to migrate my hardware into a Dell tower with much better airflow (drives are in a separate Chassis). Dells layout was too specific and I couldnt make it work so I was forced to re-install everything in the original case. Now when I boot ESXi the unraid hangs on the PLOP boot loader. Sometimes there will be a message saying the "Bootsector is the MBR", sometimes it will try to boot the ESXi Flash drive, and other times it wont recognize anything. I have checked and both the USB controller and that specific flash are being forwarded. My other windows based Plex image seems to be unaffected.

 

I would appreciate any ideas on how to move forward. I have tried putting the usb in varying locations (thinking ESXi may have originally forwarded based off hardware location) but that didnt have any effect. When I look at the USB in windows (hoping to make a backup of the USB/view config) I can see the partitions in Disk Manager but cannot assign drive letters or do anything with it., though I thought at one point I could.

 

I don't mind upgrading to 6.0 (Currently on 5.?? beta from late 2011) if I need to but I really would like to save the config information of the existing flash and not rebuild the array (~40TB) from scratch as many of the drives are nearing 5yrs.

 

 

Thank you all for your help.

Disregard, I ended up installing 6.x from the esxi thread and using partition manager to backup/reformat/reinstall all my USB information. Either way, we seem to be up and running again. . .
