I'm using VMWare ESXi 5 and had a 2 TB RAID 5 setup on an HP DL360 with a P400i RAID card. I added two more 1 TB drives and using the SmartStart ACU, added the drives and expanded the logical disk.

Now after booting back to ESXi, the server boots, but lists no available persistent storage. I've rescanned multiple times to no avail: the Datastore doesn't show up.

I booted to GParted and the 1.8TB partition shows up, but it shows as unknown. Anyone have any good ideas?

EDIT: Final Solution

So after much gnashing of teeth, it was fairly simple to solve.

I purchased an eSata 2 TB external drive and a PCI eSata card for my server.

I then used Clonezilla to image the current partitions to my new external drive. You have to check "don't check drive sizes" in advanced mode, otherwise it will yell at you for have a smaller drive.

For some reason my PCI card wouldn't boot on my HP server, so I hooked the drive up to another desktop I had, booted to VMWare, and copied the vmdk's to another drive.

I'm going to blow out the RAID config and then create 1.5TB logical drives.
