PERC 6/i doesn't see any physical drives

Would it be possible to install LSI's utility MegaCLI? You can use that to export a log straight from the controller, which may yield information regarding what the controller sees or doesn't see, and if the drives are being acknowledged at the hardware level.

Flash made a good observation. Confirming that the Control + R menu works would be a good place to  start in confirming what is seen, and that it is indeed a PERC 6. If you can make the outage without difficulty, that may be an easier place to start, since you won't need to install anything.

The device you posted is not a PERC 6 ...

You CAN get into the CTRL-R utility for the RAID controller? and it shows nothing under PD MGMT?

That is correct.  In the CTRL-R utility, PD MGMT page, under Size/MB Type: "No PD Present"

Boot screen says LSI Logic ©2008 PERC 6/i

Firmware version is 6.3.3.002 (latest available).

This is all I'm getting from your upload point, unfortunately.

Hello,

I had to download the file from home, looks like the URL was being blocked. As for the file, I found MegaSAS.log, deleted.txt, and CmdTool.log. 

MegaSAS was essentially an empty file.

CmdTool.log was a single repeating line.

Deleted.txt has some interesting information though. It does appear that the PERC saw drives at one point. Considering the situation, I'm willing to bet it is historical logging. Jumping to the bottom of the log for the newest information, it definitely appears that the controller can't see them at all as there is not even an entry saying drives were blocked.

So.  Test the card in another computer to see if the card works?

RIght, I'd probably just reinstall it into the donor system, if you still have it available.

There is what appears to be a power lead for a speaker that was connected to the motherboard coming off of J6 between the two SFF-8484 connectors on the RAID card when the card was in the PowerEdge T310 donor system.  I didn't connect it to anything when I installed the card into the PowerEdge 1800.  Could the card's inability to see any drives in the PowerEdge 1800 or the donor system be caused by this cable being disconnected?
