Hi Matt,
As another option, would the WebBIOS be useful if it’s available? On our new machines (which sounds similar, and have LSI MegRAIDs in them) there’s the option for using the WebBIOS instead of the PreCLI, which might give you another avenue of investigation.
Cheers,
David

Noticing that they had been supplied with lop-sided volumes I booted up the "preboot CLI" for the cards (essentially MegaCLI without the Mega, and much of the CLI). Like a bafoon I deleted the existing Virtual Drives with ne'er a thought for what I was doing (beyond the 15 minutes of man page searching to figure out how to take these ill thought out steps). Then followed a comedy of errors as I attempted to type the nessicery incantation to create the new volume, something like this (but expanded out);

Sadly the ipmi virtual console doesn't support pasting into it as a workaround for my inept typing either.
